Primary squamous cell carcinoma of the brain.

NEUROPATHOLOGY, Issue 3 2003
A rare autopsy case
In the present study, a rare autopsy case of primary squamous cell carcinoma of the brain is described. The patient was a 49-year-old man who showed brainstem symptoms and signs. These included oculomotor, abducens and facial palsies, dysphagia, dysarthria, and long tract signs such as quadriplegia with Babinski's signs during the 3-year and 6-month course of his illness. Neuropathologically, poorly differentiated squamous cell carcinoma was seen in the pons, medulla oblongata, part of the midbrain and spinal cord, the base of the cerebellum, the hypothalamus, the optic chiasm, and the left parahippocampal gyrus. The base of the pons and medulla oblongata were extensively destroyed by tumor cells. The relevant literature regarding primary squamous cell carcinomas of the brain was reviewed, and the characteristic features of this rare condition were discussed. [source]

Squamous cell carcinoma arising in the skin of a deltopectoral flap 27 years after pharyngeal reconstruction,

Abstract Background Development of a second primary squamous cell carcinoma in the skin of a flap used for pharyngeal reconstruction is rare. Methods A case of squamous cell carcinoma is presented arising in a deltopectoral flap used to reconstruct the hypopharynx 27 years after total laryngectomy. Three previous reports found on review of the literature are summarized. Results A second primary squamous cell carcinoma may arise in the skin of a myocutaneous flap in the absence of any obvious risk factors. Conclusion We suspect that long-term exposure of the skin of the flap lining the pharynx to saliva may have been a significant factor in the development of this malignancy. Long-term follow up and awareness of this complication is required for patients with soft tissue reconstruction of the oral cavity and pharynx. © 2002 John Wiley & Sons, Inc.

Carcinoma of the Tongue Base Treated by Transoral Laser Microsurgery, Part Two: Persistent, Recurrent and Second Primary Tumors

THE LARYNGOSCOPE, Issue 12 2006
David G. Grant MD
Abstract Objectives: To report the oncologic and functional outcomes of transoral laser microsurgery (TLM) in the treatment of persistent, recurrent, and second primary squamous cell carcinoma of the tongue base. Study Design: A two-center prospective case series analysis. Methods: Twenty-five patients with persistent, recurrent, or second primary squamous cell carcinoma of the tongue base were treated with TLM between 1997 and 2005. Four (16%) patients with persistent disease at the primary site were considered TX. Eleven (44%) patients with recurrent disease were pathologically staged rT1 3/11, rT2 2/11, rT3 4/11, T4 1/11, and TX 1/11. Ten (40%) patients with second primary tumors were staged pT1, 4/10; pT2, 3/10; pT3, 2/10; and pT4, 1/10. Eight (32%) patients underwent neck dissection. Three (12%) patients received adjuvant radiotherapy. Pre- and post-treatment organ function was assessed using a clinical Functional Outcome Swallowing Scale (FOSS) and Communication Scale. Results: The mean follow-up period was 26 months. The 2-year Kaplan-Meier local control and locoregional control estimate was 69%. For those patients presenting with persistent/recurrent or second primary disease, the 2 year local control estimates were 75% and 68%, respectively. For all patients, the respective 2 and 5 year overall survival estimates were 54% and 26%. Two (8%) patients suffered postoperative hemorrhage. The average duration of hospitalization was 3.6 days. The median pretreatment and posttreatment FOSS stage was stage 2 and stage 3, respectively. Conclusions: Transoral laser surgery is a rational and effective treatment in appropriately selected patients with persistent, recurrent, or second primary tongue base cancer. The low morbidity and mortality and shortened duration of hospitalization associated with TLM make it an attractive therapeutic alternative. [source]

,When will I see you again?' Using local recurrence data to develop a regimen for routine surveillance in post-treatment head and neck cancer patients

CLINICAL OTOLARYNGOLOGY, Issue 6 2009

Objective:, To develop an evidence-based regimen for routine surveillance of post-treatment head and neck cancer patients. Design:, Review of 10 years of prospectively collected patient data. Main outcome measures:, Time of first presentation of ,new cancer event' (either first recurrence or second primary tumour). We did not evaluate whether or not the detected new cancer events were curable. Results:, Data from patients with primary squamous cell carcinoma of the larynx, oropharynx and hypopharynx were analysed. A total of 676 previously undiagnosed squamous cell carcinomas were recorded in these regions. In these patients there were 105 recurrences and 20 second primary cancers were recorded; 95th percentile of "time to a new cancer event" was calculated in years. These were for larynx 4.7 years, oropharynx 2.7 years, hypopharynx 2.3 years. The time to new cancer event was similar for early and late laryngeal cancers. Only 36 (47%) of the hypopharyngeal cancers were treated with curative intent and of these 36% had a previously undiagnosed cancer event. Conclusion:, Local data and published evidence support a follow-up duration of 7 years for laryngeal primaries and 3 years for both oropharyngeal and hypopharyngeal primaries. Late stage oropharyngeal cancers may require longer follow up than early cancers. Patients who continue to smoke may need longer follow up. A change in local follow-up protocol to this regimen would save 10 patient slots every week with no detriment to patient care. Clin. Otolaryngol. 2009, 34, 546,551. [source]

Squamous cell carcinoma of the hand masquerading as a cutaneous infection

AUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 1 2006

SUMMARY A 33-year-old male concreter presented with a small abscess on his right index finger following an injury at work. Histological examination of the lesion was consistent with chronic inflammation and Staphylococcus aureus, Streptococcus anginosus and Escherichia coli were isolated on cultures. The lesion was treated as a chronic fungal infection with bacterial superinfection. Seventeen months later, a bone scan showed periarticular involvement, and a diagnostic biopsy identified a well-differentiated squamous cell carcinoma. He underwent amputation of his index and middle fingers. After 4 years of follow up, there has been no evidence of recurrence at the primary site, but he has since developed two further primary squamous cell carcinomas. This case emphasizes the importance of considering malignancy when dealing with chronic infections of the hand. [source]
