Selected AbstractsMalignant peripheral nerve sheath tumors of the head and neck: Management of 10 cases and literature review,HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 5 2007Amir Minovi MD Abstract Background. This study analyzes the management and outcomes of a series of 10 malignant peripheral nerve sheath tumors (MPNST) of the head and neck. Methods. From 1984 to 2004, 10 patients underwent surgical treatment of a MPNST. We retrospectively reviewed presenting symptoms, radiological findings, surgical management, and follow-up status and performed a literature review. Results. Eight tumors were located at the lateral skull base; 2 involved the vagus nerve in isolation. Two lesions were growing within the sinonasal tract. The most common presenting symptom was a rapidly enlarging cervical mass. Seventy percent of the tumors could be resected completely. Long-term follow-up showed a 2-year disease-specific survival rate of 50% and 5-year survival rate of 20%. Negative prognostic indicators were advanced tumor stage, early recurrence, and presumably also the presence of von Recklinghausen's disease. Postoperative adjuvant radiotherapy was found to make no difference in outcome. Conclusions. Although rare, MPNST is one of the most aggressive tumors in the head and neck area. Complete tumor removal is the mainstay of treatment and most important prognostic factor of MPNST. Adjuvant radiotherapy should be used to assist surgical excision in local control. The role of adjuvant chemotherapy remains controversial. © 2006 Wiley Periodicals, Inc. Head Neck, 2007. [source] Folliculosebaceous cystic hamartoma of the nipple: a case reportJOURNAL OF CUTANEOUS PATHOLOGY, Issue 5 2009AbdullGaffar Badr Folliculosebaceous cystic hamartoma (FCH) is a relatively rare and recently described lesion of the skin. Mostly, it involves the skin of the head and neck area. It is considered by most authors as a form of non-neoplastic cutaneous hamartoma comprising follicular, sebaceous and stromal elements. However, few regard it as a sebaceous trichofolliculoma, i.e. a variant of trichofolliculoma. FCH of the nipple of female breast is a very rare lesion with only one previous case reported so far in the literature. We report a similar case with a brief review of the literature. [source] Treatment of vitiligo vulgaris with narrow-band UVB and oral Polypodium leucotomos extract: a randomized double-blind placebo-controlled studyJOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 7 2007MA Middelkamp-Hup Abstract Background, The first choice treatment for vitiligo vulgaris is narrow-band UVB (NB-UVB), but no satisfactory treatment exists. Objectives, To investigate if Polypodium leucotomos, an antioxidative and immunomodulatory plant extract, improves NB-UVB-induced repigmentation. Methods, Fifty patients with vitiligo vulgaris randomly received 250 mg oral P. leucotomos or placebo three times daily, combined with NB-UVB twice weekly for 25,26 weeks. Results, Repigmentation was higher in the P. leucotomos group vs. placebo in the head and neck area (44% vs. 27%, P = 0.06). Small repigmentation increases (P = n.s.) were observed for the trunk (6% increased repigmentation), extremities (4%), and hands and feet (5%) in the P. leucotomos group vs. placebo. Patients attending more than 80% of required NB-UVB sessions showed increased repigmentation in the head and neck area in the P. leucotomos group vs. placebo (50% vs. 19%, P < 0.002); no significant differences were seen in the other body areas. Patients with skin types 2 and 3 showed more repigmentation in the head and neck area in the P. leucotomos group vs. placebo (47% vs. 21%, P = 0.01), and no significant differences were seen in the other body areas. No conclusions could be drawn on skin types 4 and 5 due to low patient numbers. Conclusion, There is a clear trend towards an increase in repigmentation of vitiligo vulgaris affecting the head and neck area when NB-UVB phototherapy is combined with oral P. leucotomos. This effect may be more pronounced in light skin types. [source] Is head and neck melanoma a distinct entity?BRITISH JOURNAL OF DERMATOLOGY, Issue 4 2006A clinical registry-based comparative study in 5702 patients with melanoma Summary Background, The head and neck region is more heavily exposed to ultraviolet (UV) radiation than any other body site. Therefore, cutaneous malignant melanoma (CMM) of the head and neck area is proposed to have notable differences from melanoma at other body sites regarding clinicopathological features and survival of patients. Objectives, The present retrospective study based on clinical registry data aims to compare clinical features and prognostic factors of head and neck melanoma (HNM) vs. melanoma at other anatomical regions (MOR) in order to detect differences which may be associated to the mode of sun exposure. Methods, The clinical records and histopathological findings of 844 patients with clinical stage I and II invasive HNM were compared with the data of 4858 patients with MOR. Survival analysis was performed using the Kaplan,Meier estimate, and the multivariate Cox proportional hazard model was used to evaluate independent prognostic factors. Results, Melanoma density was clearly higher for HNM than for MOR: this was particularly true for the face, where it was elevated by a factor of 2·6. There was a higher male/female ratio in patients with HNM and they were significantly older than patients with MOR (P < 0·0001). Breslow tumour thickness did not differ between HNM and MOR. However, CMMs at the scalp were significantly thicker and to a higher degree ulcerated. Concerning clinicopathological CMM subtypes, there was an increased proportion of lentigo maligna melanoma among HNM and of nodular melanoma in the scalp and neck regions. Excision margins were narrower and the rate of complete primary excision was lower in HNM than in MOR. Overall, there was no significant statistical difference in cumulative 10-year survival rates according to Kaplan,Meier estimates among patients with HNM (84·6%) and MOR (87·8%). Tumour thickness turned out to be the variable with the highest prognostic impact followed by ulceration in both HNM and MOR. Conclusions, In relation to the skin surface significantly more CMMs were found in the head and neck area than in other anatomical regions. This might indicate, but does not prove, that UV exposure promotes the development of CMM. Although HNM showed specific clinicopathological features, prognosis remained unaffected. Thus HNM seems not to be a distinct subtype of CMM. [source] Clinical implications of nodal marginal zone B-cell lymphoma among Japanese: study of 65 casesCANCER SCIENCE, Issue 1 2007Masaru Kojima To clarify the clinical presentation and outcome of nodal marginal zone B-cell lymphoma (NMZBL), 65 Japanese patients with this disease were studied and compared with the published literature from western countries. The clinical findings of our 65 cases were similar to those of their cases in some aspects: (1) 58% of the patients were >60 years old (median age, 64 years); (2) there was a slight female predominance; (3) 90% of the patients exhibited asymptomatic lymphadenopathy in the head and neck area; (4) only a minority of patients had B symptoms (6%) and poor performance status (8%); and (5) only 5% of patients were positive for M-protein. However, the 65 patients in this series exhibited relatively longer 5-year overall survival (85%) and failure-free survival (60%) than the NMZBL series published in western literature, suggesting that NMZBL should be classified as indolent lymphoma. Moreover, based on the histological findings, we further classified four histological subtypes as follows: (1) splenic type (n = 7); (2) floral type (n = 9); (3) mucosa-associated lymphoid tissue (MALT) type (n = 29); and (4) diffuse large B-cell lymphoma (DLBCL) + MALT type (n = 20). DLBCL + MALT type exhibited significantly poorer 5-year overall survival than the splenic variant. The recognition of DLBCL + MALT type appears important. No API2,MALT1 fusion transcript was detected in any of the 14 cases examined. (Cancer Sci 2007; 98: 44,49) [source] | ||||||||||
