Sebaceous cell carcinoma of the parotid gland is a rare lesion. A review of the English literature reveals nine previously reported cases. Two cases are presented in which the tumor was originally diagnosed as mucoepidermoid carcinoma. Aggressive treatment of the recurrence, which was subsequently recognized as sebaceous cell carcinoma has resulted in apparent cure. Histologic features and possible histogenesis are discussed.

A Head and Neck Sarcoma Registry was established by the Society of Head and Neck Surgeons to review treatment results of a rare tumor by surgeons with special interest in this anatomic site. Two hundred fourteen patients were analyzed. There were 194 adult tumors and 20 pediatric tumors. The major sites included parotid and neck, 20%; face and forehead, 18%; maxilla and palate, 13%; scalp, 12%; mandible, 11%; paranasal sinuses, 7%; larynx, 2%; and oral cavity, 5%. Eighty-four percent were resectable. The disease-free survival was 56%; overall survival was 70% at 5 years. Major determinants of survival were adequacy of resection (margins free of tumor) and tumor type. Survival differed according to tumor cell type (tumor grade was not available). Patients with chondrosarcoma and dermatofibrosarcoma had survival approaching 100%. Patients with malignant fibrous histiocytoma (MFH) and fibrosarcoma (FSA) had intermediate survival of 60% to 70%. The worst survival, less than 50% at 5 years, occurred in patients with osteosarcoma, angiosarcoma, and rhabdomyosarcoma in decreasing order. This suggests a rationale for identifying high-risk patients for prospective adjuvant protocols. This study emphasizes the value of recording uncommon tumors to provide relevant information for future study and possibly therapy.
PURPOSE: The authors analyzed the safety and efficacy of transperitoneal percutaneous cholecystostomy (PC) in patients with acute cholecystitis. PATIENTS AND METHODS: Thirty-four consecutive patients underwent transperitoneal PC for treatment of acute cholecystitis. A trocar technique was used for placement of the drainage catheter. RESULTS: PC was technically successful in all patients. In 27 (79%) of 34 patients, symptoms of acute cholecystitis resolved within 7 days. Minor complications occurred in two patients (5%). Both patients developed a hematoma adjacent to the gallbladder; these resolved without treatment. No cases of bile leak or bile peritonitis occurred. CONCLUSION: The transperitoneal route is safe and effective for PC.

PURPOSE: To determine the effect of extent of peritoneal contamination in enteric abscesses on final outcome and duration of percutaneous drainage. PATIENTS AND METHODS: Results were retrospectively reviewed for 11 patients with varying degrees of peritoneal contamination secondary to subacute bowel perforation who were primarily treated with percutaneous drainage. Stepwise linear regression analysis of duration of drainage was performed with use of patient age and immune status, the site of bowel perforation, and the number of peritoneal compartments involved in the resultant contamination as independent variables. RESULTS: In 10 of 11 patients (91%) treatment of the resultant intraperitoneal collections with percutaneous drainage was successful irrespective of the extent of peritoneal contamination. There was no correlation between duration of drainage and extent of peritoneal contamination but good correlation with patient age and site of bowel perforation (r = 0.82, P = .02). CONCLUSION: In patients with enteric abscesses due to subacute bowel perforation, the duration of drainage and final outcome after percutaneous drainage are independent of the extent of peritoneal contamination.
