    In patients with superficial esophageal cancer, especially in those with tumor invasion above the muscularis mucosae, lymph node metastasis is very rare. We report a case of superficial esophageal cancer who presented with lymph node metastasis. In another hospital a 49-year-old man was found to have a bulky tumor adjacent to the cardiac area of the stomach and a total gastrectomy was carried out. Postoperatively, the tumor was identified as a lymph node containing metastatic squamous cell carcinoma. The main lesion could not be identified on fluorodeoxyglucose positron emission tomography. On esophagogastric endoscopy, using the iodine spray technique, we found an unstained lesion about 32 cm from the incisor teeth. The tumor was removed using endoscopic mucosal resection. The entire resected specimen was examined histopathologically; the depth of the tumor was above the muscularis mucosae. Thirty-four months after endoscopic mucosal resection, there is no sign of tumor recurrence or metastasis. [source]

    Background:, Recently, esophageal microcancers have been frequently diagnosed and are receiving increasing attention as initial findings of cancer. We examined whether the clinicopathological features and microvascular patterns of esophageal microcancers on magnifying endoscopy are useful for diagnosis. Methods:, Magnifying endoscopy was performed to examine the histopathological features of 55 esophageal cancers measuring ,10 mm in diameter (34 small cancers, 16 microcancers, and five supermicrocancers). Results:, Although some lesions were detected only on iodine staining, most were detected on conventional endoscopic examination. Most small cancers and microcancers were m1 or m2; some were m3 or sm2. Supermicrocancers were dysplasia or m1 cancer. As for the microvascular pattern, most m1 and m2 cancers showed type 3 vessels, while most submucosal cancers showed type 4 vessels. Conclusions:, Microvascular patterns on magnifying endoscopy are useful for the differential diagnosis of benign and malignant esophageal cancers and for estimating the depth of tumor invasion. The shape of small lesions is often altered considerably by biopsy. Residual tumor may persist unless the basal layer of the lesion is included in biopsy specimens, even in microcancers. Consequently, endoscopic mucosal resection, without biopsy, is being performed in increasing numbers of patients with lesions suspected to be cancer on the basis of their microvascular patterns.

    Purpose With an incidence rate of 300 cases per 100000 population per year, Australia has the highest incidence of cutaneous squamous cell carcinoma (SCC) in the world. Metastatic cutaneous SCC in parotid lymph nodes are aggressive tumours with poor outcomes both in terms of local control and survival. Methodology This study reports a prospective series of 41 consecutive patients with metastatic SCC to the parotid gland in a major teaching hospital in Western Australia over a six-year period from January 2000 to December 2005. Epidemiological, clinical, histopathological and treatment details along with patterns of failure were extracted from the database. The survival and failure curves were calculated using the Kaplan-Meier method. Univariate and multivariate analysis were performed using Cox regression method. Results The five-year absolute survival is 34.2% and the cancer specific survival 39.5%. Local failure was observed in 11 patients for an actuarial rate of local disease free survival of 65.8% at 6 years. Distant failure occurred in two patients for an actuarial distant disease free survival of 89.5% at 6 years. Both univariate and multivariate analysis failed to find any predictors of local or distant failure with statistical significance. Conclusions Multimodality treatment will still fail to locally control or cure at least a third of patients. Previously identified risk factors were not substantiated in this study and may relate to patient numbers. Parotidectomy and post-operative radiotherapy remain the gold standard. Unlike their cutaneous counter parts metastatic SCC to the parotid gland remains an aggressive tumour with current treatment regimes. [source]

    Background: Squamous cell carcinoma (SCC) of the lower lip is a common malignancy in Australia. Surgical excision and/or radiotherapy are used in treatment, and are regarded as equally effective. Methods: A retrospective review of 323 patients treated at the Peter MacCallum Cancer Institute with either surgical excision and/or radiotherapy, evaluated disease recurrence, cause-specific mortality, and the incidence of metachronous lesions. Results: Recurrence-free survival at 10 years was estimated to be 92.5%, and cause-specific survival at 10 years was estimated to be 98.0%. Equivalent rates of local control were obtained with surgery and radiotherapy. Recurrence was related to tumour stage and differentiation. A high incidence of metachronous lesions was noted, 25 patients had a lesion prior to presentation and 33 patients developed second lip lesions during the study period. Conclusions: Squamous cell carcinoma of the lower lip is well treated with surgery or radiotherapy. The preferred treatment for most patients with SCC of the lower lip in the Australian population is surgical excision. This study has shown a significant incidence of metachronous lip neoplasia, except in those patients whose whole lip had been resurfaced. [source]

    Reduction in the Incidence of Squamous Cell Carcinoma in Solid Organ Transplant Recipients Treated with Cyclic Photodynamic Therapy

    BACKGROUND AND OBJECTIVES Squamous cell carcinomas (SCCs) produce significant morbidity in solid organ transplant recipients (SOTRs), particularly in patients who develop multiple tumors. Topical photodynamic therapy (PDT) has been shown to decrease the number of keratotic lesions in SOTRs, but the duration of the beneficial effect is limited. The aim of this study was to evaluate the potential benefit of cyclic PDT in the prevention of new SCCs in SOTRs. METHODS Twelve high-risk SOTRs received cyclic PDT treatments at 4- to 8-week intervals for 2 years. The development of new SCCs (invasive and in situ) performed 12 and 24 months after the start of cyclic PDT were compared with the number of SCCs developed during the year before initiation of cyclic PDT. RESULTS The median reduction in the 12- and 24-month post-treatment counts from the 1-month pretreatment counts was 79.0% (73.3,81.8%) and 95.0% (87.5,100.0%), respectively. Treatments were well tolerated. CONCLUSION Cyclic PDT with 5-aminolevulinic acid may reduce the incidence of SCC in SOTRs. Additional studies with larger numbers of patients and optimized protocols are necessary to further explore the potential benefits of cyclic PDT in the prevention of skin cancer in this high-risk patient population.

    Diameter of Involved Nerves Predicts Outcomes in Cutaneous Squamous Cell Carcinoma with Perineural Invasion: An Investigator-Blinded Retrospective Cohort Study

    BACKGROUND Perineural invasion (PNI) has been associated with poor prognosis in cutaneous squamous cell carcinoma (CSCC), but it is unclear how different degrees of nerve involvement affect prognosis. OBJECTIVE To determine whether the diameter of nerves invaded by CSCC affects outcomes of recurrence, metastasis, and disease-specific and overall survival. METHODS A retrospective cohort study was conducted of patients with CSCC with PNI. Dermatopathologists blinded to subject outcomes determined the diameter of the largest involved nerve. RESULTS Data were obtainable for 48 patients. Small-caliber nerve invasion (SCNI) of nerves less than 0.1 mm in diameter was associated with significantly lower risks of all outcomes of interest. Disease-specific death was 0% in subjects with SCNI, versus 32% in those with large-caliber nerve invasion (LCNI) (p=.003). Other factors associated with significantly worse survival were recurrent or poorly differentiated tumors or tumor diameter of 2 cm or greater or depth of 1 cm or greater. On multivariate analysis, only tumor diameter and age predicted survival. CONCLUSIONS The individual prognostic significance of factors associated with poor survival remains uncertain. Small-caliber nerve invasion may not adversely affect outcomes. Defining PNI as tumor cells within the nerve sheath and routine recording of diameter of involved nerves, tumor depth, and histologic differentiation on pathology reports will facilitate further study.

    Surgical Monotherapy Versus Surgery Plus Adjuvant Radiotherapy in High-Risk Cutaneous Squamous Cell Carcinoma: A Systematic Review of Outcomes

    BACKGROUND Adjuvant radiotherapy (ART) has been recommended for squamous cell carcinoma (SCC) with a high risk of recurrence, particularly perineurally invasive disease. The utility of ART is unknown. This study compares reported outcomes of high-risk SCC treated with surgical monotherapy (SM) with those of surgery plus ART (S+ART). METHODS The Medline database was searched for reports of high-risk SCC treated with SM or S+ART that reported outcomes of interest: local recurrence, regional or distant metastasis, or disease-specific death. RESULTS There were no controlled trials. Of the 2,449 cases of high-risk SCC included, 91 were treated with S+ART. Tumor stage and surgical margin status before ART were generally unreported. In 74 cases of perineural invasion (PNI), outcomes were statistically similar between SM and S+ART. In 943 high-risk SCC cases in which clear surgical margins were explicitly documented, risks of local recurrence, regional metastasis, distant metastasis, and disease-specific death were 5%, 5%, 1%, and 1%, respectively. CONCLUSIONS High cure rates are achieved in high-risk cutaneous SCC when clear surgical margins are obtained. Current data are insufficient to identify high-risk features in which ART may be beneficial. In cases of PNI, the extent of nerve involvement appears to affect outcomes, with involvement of larger nerves imparting a worse prognosis. [source]

    Test Characteristics of High-Resolution Ultrasound in the Preoperative Assessment of Margins of Basal Cell and Squamous Cell Carcinoma in Patients Undergoing Mohs Micrographic Surgery

    BACKGROUND Noninvasive techniques to assess subclinical spread of nonmelanoma skin cancer (NMSC) may improve surgical precision. High-resolution ultrasound has shown promise in evaluating the extent of NMSC. OBJECTIVES To determine the accuracy of high-resolution ultrasound to assess the margins of basal cell (BCC) and squamous cell carcinomas (SCC) before Mohs micrographic surgery (MMS). METHODS We enrolled 100 patients with invasive SCC or BCC. Before the first stage of MMS, a Mohs surgeon delineated the intended surgical margin. Subsequently, a trained ultrasound technologist independently evaluated disease extent using the EPISCAN I-200 to evaluate tumor extent beyond this margin. The accuracy of high-resolution ultrasound was subsequently tested by comparison with pathology from frozen sections. RESULTS The test characteristics of the high-resolution ultrasound were sensitivity=32%, specificity=88%, positive predictive value=47%, and negative predictive value=79%. Subgroup analyses demonstrated better test characteristics for tumors larger than the median (area>1.74 cm2). Qualitative analyses showed that high-resolution ultrasound was less likely to identify extension from tumors with subtle areas of extension, such as small foci of dermal invasion from infiltrative SCC and micronodular BCC. CONCLUSION High-resolution ultrasound requires additional refinements to improve the preoperative determination of tumor extent before surgical treatment of NMSC. [source]

    High-Risk Cutaneous Squamous Cell Carcinoma without Palpable Lymphadenopathy: Is There a Therapeutic Role for Elective Neck Dissection?

    PURPOSE The beneficial role of elective neck dissection (END) in the management of high-risk cutaneous squamous cell carcinoma (CSCC) of the head and neck remains unproven. Some surgical specialists suggest that END may be beneficial for patients with clinically node-negative (N0) high-risk CSCC, but there are few data to support this claim. We reviewed the available literature regarding the use of END in the management of both CSCC and head and neck SCC (HNSCC). METHODOLOGY The available medical literature pertaining to END in both CSCC and HNSCC was reviewed using PubMed and Ovid Medline searches. RESULTS Many surgical specialists recommend that END be routinely performed in patients with N0 HNSCC when the risk of occult metastases is estimated to exceed 20%; however, patients who undergo END have no proven survival benefit over those who are initially staged as N0 and undergo therapeutic neck dissection (TND) after the development of apparent regional disease. There is a lack of data regarding the proper management of regional nodal basins in patients with N0 CSCC. In the absence of evidence-based data, the cutaneous surgeon must rely on clinical judgment to guide the management of patients with N0 high-risk CSCC of the head and neck. CONCLUSIONS Appropriate work-up for occult nodal disease may occasionally be warranted in patients with high-risk CSCC. END may play a role in only a very limited number of patients with high-risk CSCC. [source]

    Sentinel Lymph Node Biopsy in Cutaneous Squamous Cell Carcinoma: A Systematic Review of the English Literature

    BACKGROUND Although most cutaneous squamous cell carcinoma (SCC) is curable by a variety of treatment modalities, a small subset of tumors recur, metastasize, and result in death. Although risk factors for metastasis have been described, there are little data available on appropriate workup and staging of patients with high-risk SCC. OBJECTIVE We reviewed reported cases and case series of SCC in which sentinel lymph node biopsy (SLNB) was performed to determine whether further research is warranted in developing SLNB as a staging tool for patients with high-risk SCC. METHODS The English medical literature was reviewed for reports of SLNB in patients with cutaneous SCC. Data from anogenital and nonanogenital cases were collected and analyzed separately. The percentage of cases with a positive sentinel lymph node (SLN) was calculated. False negative and nondetection rates were tabulated. Rates of local recurrence, nodal and distant metastasis, and disease-specific death were reported. RESULTS A total of 607 patients with anogenital SCC and 85 patients with nonanogenital SCC were included in the analysis. A SLN could not be identified in 3% of anogenital and 4% of nonanogenital cases. SLNB was positive in 24% of anogenital and 21% of nonanogenital patients. False-negative rates as determined by completion lymphadenectomy were 4% (8/213) and 5% (1/20), respectively. Most false-negative results were reported in studies from 2000 or earlier in which the combination of radioisotope and blue dye was not used in the SLN localization process. Complications were reported rarely and were limited to hematoma, seroma, cutaneous lymphatic fistula, wound infection, and dehiscence. CONCLUSIONS Owing to the lack of controlled studies, it is premature to draw conclusions regarding the utility of SLNB in SCC. The available data, however, suggest that SLNB accurately diagnoses subclinical lymph node metastasis with few false-negative results and low morbidity. Controlled studies are needed to demonstrate whether early detection of subclinical nodal metastasis will lead to improved disease-free or overall survival for patients with high-risk SCC. [source]

    p75NGFR Immunostaining for the Detection of Perineural Invasion by Cutaneous Squamous Cell Carcinoma

    BACKGROUND Perineural invasion (PNI) in cutaneous squamous cell carcinoma (CSCC) may portend a poor prognosis for patients. p75NGFR (nerve growth factor receptor) is part of a membrane receptor complex that binds nerve growth factor. Its use for detecting PNI in CSCC in comparison to S-100 immunohistochemical staining has not been explored. OBJECTIVE To determine whether detection of PNI may be improved by staining with p75NGFR as compared with hematoxylin and eosin (H&E) and S-100. METHODS Thirty-four cases of CSCC were retrospectively evaluated for the presence of PNI using standard H&E as well as S-100 and p75NGFR immunohistochemical stains. Staining intensity was correlated to the presence or absence of PNI and tumor differentiation. RESULTS Results showed a positive correlation between staining intensity and the presence of PNI detected by p75NGFR (p=.04). Using p75NGFR allowed for the detection of seven cases of PNI not detected by H&E alone. Five of these cases were detected by S-100, with two cases seen by p75NGFR only. Six cases of PNI were detected using S-100 not seen on H&E, with one case also not seen using p75NGFR. CONCLUSION p75NGFR immunostaining increased detection of PNI compared with H&E. p75NGFR could serve as an alternative to S-100 in the detection of PNI, or as part of an immunostaining panel for PNI detection.

    Squamous Cell Carcinoma of the Lower Lip: Exact Location Match in Siblings

    Dogan Tuncali MD
    Background. In recent years, genetic contribution to the development of skin cancers is under the magnifying glass of several authors and is now regarded as the main initial etiology in carcinogenesis. Objective. Two siblings who had squamous cell carcinoma of the lower lip showing an exact location match are presented. Patients. They did not share common environmental factors, and there was no history of tobacco and/or alcohol abuse. Conclusions. It would be scientifically deceptive to draw generous conclusions for the cases here, other than being a very interesting and unusual coincidence, because further evaluation could not be done to scientifically prove a possible genetic contribution.

    Evaluation of the American Joint Committee on Cancer Staging System for Cutaneous Squamous Cell Carcinoma and Proposal of a New Staging System

    Scott M. Dinehart MD
    Purpose. To identify and propose corrections for deficiencies in the American Joint Committee on Cancer (AJCC) system for staging cutaneous squamous cell carcinoma (CSCC). Materials and Methods. Prognostic factors for CSCC were identified by retrospective analysis of the published literature. Limitations and deficiencies in the current AJCC staging system for CSCC were then determined using these prognostic factors. Results. Size, histologic differentiation, location, previous treatment, depth of invasion, tumor thickness, histologic subtype, perineural spread, and scar etiology are the most powerful tumor prognostic indicators in patients with localized disease. The most important prognostic factors for patients with nodal metastases are the location, number, and size of the positive lymph nodes. Proposed changes for the T classification include increased stratification of tumor size, identification of patients with perineural invasion, and the addition of tumor thickness or depth of invasion. The N classification has been expanded to include the number and size of nodal metastases. Conclusion. The current AJCC staging system for carcinoma of the skin has deficiencies that limit its use for CSCC. The proposed TMN staging system for CSCC more accurately reflects the prognosis and natural history of CSCC. SCOTT M. DINEHART, MD, AND STEVEN PETERSON, MD, HAVE INDICATED NO SIGNIFICANT INTEREST WITH COMMERCIAL SUPPORTERS. [source]

    Late Inguinal Metastasis of a Well-Differentiated Subungual Squamous Cell Carcinoma after Radical Toe Amputation

    Kuo-Chin Huang MD
    Background Although squamous cell carcinoma (SCC) is commonly found on sun-exposed skin, this malignancy in nail beds is rare. There is a very low rate of metastases, especially for well-differentiated lesions without bony involvement. Objective To present a case of late inguinal metastasis after radical toe amputation 3 years previously for subungual SCC. Materials and Methods Case report. Results The patient received modified inguinal lymphadenectomy and adjuvant radiation therapy. No recurrence or metastases were observed for 12 months. Conclusion For patients with subungual SCC postsurgery, it is important to regularly evaluate for a minimum of 3 years, despite the very low rate of metastases. [source]

    Guidelines for the Management of Squamous Cell Carcinoma in Organ Transplant Recipients

    DERMATOLOGIC SURGERY, Issue 4p2 2004
    Thomas Stasko MD
    Background. Solid-organ transplant recipients have a high incidence of cutaneous squamous cell carcinoma (SCC) and often develop multiple and aggressive tumors. There are few published studies or reviews, which provide guidance to the clinician in the treatment of these patients. Objective. The objective was to develop useful clinical guidelines for the treatment of skin cancer in organ transplant recipients (OTRs). Methods. The members of the Guidelines Committee of the International Transplant,Skin Cancer Collaborative (ITSCC) carried out a computerized search utilizing the databases of the National Library of Medicine for reports in the literature on SCC in OTRs. These reports were collectively examined by the group and combined with experiences from the members' clinical practices in the development of the guidelines. Results. More than 300 articles relating to SCC in OTRs were reviewed. In general, reports concerning the prevention and treatment of SCC in OTRs are of individual cases or small case series. They are retrospective in nature, statistically nonrigorous, and lack the complete epidemiologic data necessary to derive definitive conclusions. Combining these studies and collective clinical experience, however, is at present the best available method for devising guidelines for the treatment of SCC in OTRs. Conclusion. Guidelines developed for the treatment of skin cancer in OTRs, supported by the best available data and collective clinical experience, may assist in the management of OTRs with SCC. The development of clinical pathways and complete documentation with rigorous prospective study is necessary to improve and refine future guideline development. [source]

    In-Transit Metastasis From Primary Cutaneous Squamous Cell Carcinoma in Organ Transplant Recipients and Nonimmunosuppressed Patients: Clinical Characteristics, Management, and Outcome in a Series of 21 Patients

    DERMATOLOGIC SURGERY, Issue 4p2 2004
    John A. Carucci MD
    Background. In-transit metastases from cutaneous squamous cell carcinoma (SCC) may occur in organ transplant recipients and may indicate aggressive disease and poor prognosis. Objective. The objective of this study was to describe in-transit metastases from cutaneous SCC and to identify factors associated with this phenomenon in a series of 21 patients. We also attempted to evaluate outcome with respect to status as an organ transplant recipient or nonorgan transplant recipient. Methods. A multicenter case series of patients was reviewed; factors included clinical presentation, management, and outcome. Results. Twenty-one patients, 15 organ transplant recipients, and 6 nontransplant recipients with in-transit metastases were reviewed. In-transit metastases presented most commonly as discrete, dermal papules distinct from but in the vicinity of the primary tumor site. Histologic differentiation was variable. At a mean follow up of 24 months, 33% the transplant patients had no evidence of disease compared with 80% of nontransplant patients. Thirty-three percent were dead from disease and 33% were alive with nodal or distant metastases. In contrast, 80% of nonimmunosuppressed patients had no evidence of disease and none had died at mean follow-up of 24 months. Conclusion. In-transit metastasis from cutaneous SCC is a unique presentation of metastatic SCC, more commonly described in organ transplant recipients, and is associated with poor prognosis in that group. This description represents the largest experience with in-transit metastases from cutaneous SCC in the literature. [source]

    Squamous Cell Carcinoma of the Anal Margin with Pruritus Ani of Long Duration

    Yoshihiro Handa MD
    BACKGROUND. Anal margin is an unusual location for squamous cell carcinoma (SCC). On rare occasions, anal margin carcinoma is the cause of pruritus ani. OBJECTIVE. To describe a case of SCC of the anal margin with pruritus ani of long duration. RESULTS. A 52-year-old man had been aware of perianal itching for over 10 years. Examination of the perianal area revealed a reddish, eroded, hard nodule that was 2.0×1.5 ×0.3 cm in size located in the 3 o'clock position. The histopathologic diagnosis was well-differentiated SCC. The nodule was totally excised with a 1-cm margin. No recurrence or metastases were observed for 7 months. CONCLUSION. When pruritus ani does not respond to conservative therapy and when symptoms have existed for a long time, we should suspect the presence of malignancy. [source]

    Squamous Cell Carcinoma in Chronic Lymphedema: Case Report and Review of the Literature

    Hiroshi Furukawa MD
    background. Squamous cell carcinoma (SCC) arising in chronic lymphedema is rare; only nine cases have been reported. objective. To present the evolution of SCC in chronic lymphedema. methods. Case report and literature review. results. The tumor was treated by wide excision and covered by a skin graft. conclusion. In most of the other reported SCC cases in lymphedema, there are additional factors for carcinogenesis. There is no additional carcinogenic factor except for chronic lymphedema in our case. This strongly supports that lymphedema itself is one of the carcinogenic factors for not only angiosarcoma but also SCC. [source]

    Pigmented Bowen's Disease (Squamous Cell Carcinoma in situ): A Mimic of Malignant Melanoma

    Ravi Krishnan MD
    Background. Darkly pigmented individuals may manifest unusual or uncharacteristic presentations of various skin conditions, including heavy pigmentation of cutaneous tumors. Objective. To increase the awareness of an unusual presentation of Bowen's disease in a darkly pigmented individual. Methods. We report the case of a 52 year old black woman that presented with a lesion clinically consistent with malignant melanoma. However, histopathologic examination revealed pigmented Bowen's disease. Results. A biopsy is almost always indicated to confirm the diagnosis of lesions in darkly pigmented individuals. Conclusion. This case is presented to reinforce the idea that pigmented Bowen's disease should be considered in the differential diagnosis of malignant melanoma. [source]

    Chronic Atrophic Gastritis and Metachronous Gastric Cancer in Japanese Alcoholic Men With Esophageal Squamous Cell Carcinoma

    ALCOHOLISM, Issue 5 2009
    Akira Yokoyama
    Background:, The risk of metachronous gastric cancer is high in Japanese with esophageal squamous cell carcinoma (SCC), especially in alcoholic men, suggesting a common background underlying the gastric and esophageal cancers. Methods:, Endoscopic follow-up ranging from 7 to 160 months (median, 47 months) after the initial diagnosis was performed in 99 Japanese gastric-cancer-free alcoholic men (56.8 ± 6.4 years) with esophageal SCC detected by an endoscopic screening examination. Chronic atrophic gastritis (CAG) assessed by the serum pepsinogen test and Helicobacter pylori status was compared between 90 of the 99 esophageal SCC cases and 180 age-matched Japanese gastric- and esophageal-cancer-free alcoholic men. Results:, The serum pepsinogen test showed a higher seroprevalence of severe CAG among the cases than among the age-matched controls (35.4% vs. 14.2% for H. pylori -seropositive, 71.4% vs. 7.7% for H. pylori -indeterminate, and 17.1% vs. 9.8% for H. pylori -negative, respectively; H. pylori status-adjusted p = 0.0008), whereas their H. pylori status was similar. The accelerated progression of severe CAG observed in the Japanese alcoholic men with esophageal SCC suggests the existence of common mechanisms by which both esophageal SCC and H. pylori -related severe CAG develop in this population. Metachronous gastric adenocarcinoma was diagnosed in 11 of the 99 gastric-cancer-free patients, and the cumulative rate of metachronous gastric cancer within 5 years was estimated to be 15% according to the Kaplan,Meier method. The age-adjusted hazard ratios were 7.87 (95% confidence interval: 1.43 to 43.46) and 4.84 (1.16 to 20.21), respectively, in the patients with severe CAG in comparison with those without CAG and those without severe CAG. Inactive heterozygous aldehyde dehydrogenase-2, a very strong risk factor for esophageal SCC in the alcoholics, was not associated with an increased risk of metachronous gastric cancer. Conclusions:, Accelerated development of severe CAG at least partially explained the very high frequency of development of metachronous gastric cancer in this population. [source]

    Lower Lip Squamous Cell Carcinoma in Disabling Pansclerotic Morphea of Childhood

    Ivaylo Petrov M.D.
    As DPMC is extremely rare, its association with skin squamous cell carcinoma (SCC) is rarer still. To our knowledge there are only two cases of SCC in patients with DPMC that developed within areas of chronic skin ulceration. We report the first case of lower lip squamous cell carcinoma arising in a young woman with DPMC and discuss the carcinogenic pathway that may have led to its occurrence. [source]
