ABSTRACT
Muir-Torre syndrome (MTS) is a rare phenotypic variant of hereditary non-polyposis colorectal carcinoma (HNPCC, Lynch syndrome), in which patients, in addition to visceral carcinomas, develop skin tumors. Multiple keratoacanthomas and basal cell carcinomas with sebocytic differentiation are characteristic as well as multiple benign and malignant tumors of the sebaceous glands, such as sebaceous adenoma, sebaceous epithelioma (sebaceoma) and sebaceous carcinoma. Particularly Cystic tumors of the sebaceous glands are especially suggestive of MTS. In genetically predisposed persons, cutaneous and visceral tumors are diagnosed at an average age of 53 years. Here we present an interesting case of a 65-year-old man in whom molecular genetic tests revealed a novel mutation in the MSH2 gene, leading to a frame shift within the gene.

BACKGROUND: The aim of this study was to compare the efficacy and tolerability of topically applied ciclopiroxolamine cream with that of the corresponding vehicle in patients with seborrheic dermatitis of the face. PATIENTS AND METHODS: The study was conducted as a multicenter prospective, randomized, double-blind parallel group comparison at 14 centers in Australia and New Zealand. 189 patients with clinically diagnosed seborrheic dermatitis participated in the study. Each patient applied ciclopiroxolamine 1% cream or the corresponding vehicle twice daily as a thin film to the affected skin areas and to clinically unaffected skin areas surrounding the lesions for 29 days. RESULTS: The rate of treatment success was significantly higher with ciclopiroxolamine than with vehicle (73.9 vs 53.6%; p = 0.003). Treatment with ciclopiroxolamine reduced the sum score of the clinical signs of seborrheic dermatitis to a greater extent than the vehicle (p
