The predisposition to epithelial neoplasms in nevus sebaceous is well established; most tumors occur in adults and are benign. Hidradenoma is a relatively rare benign tumor of sweat gland origin that can rarely arise within a nevus sebaceous. We present an interesting case of a hidradenoma and sebaceoma arising within a nevus sebaceous and present a literature review of the 2 conditions. Even t...
Presented here are three cutaneous sebaceous tumors (one carcinoma and two sebaceomas), each demonstrating a focal glandular pattern representing apocrine differentiation. The patients, two males and one female, each clinically presented with a small solitary nodule or tumor on the scalp. None of the patients had features of Muir-Torre syndrome. Surgical removal of the lesions was performed in ...
A 68-year-old Japanese man presented with a nodule that had been present for 5 to 6 years on the right side of the back. Physical examination revealed a dome-shaped, 12 x 13-mm, dark red nodule. It was excised with a 2 to 3-mm margin. The patient remained free of disease during 77 months of follow-up. Microscopic examination revealed a bulb-like tumor in the dermis, contiguous with the overlyin...
CNS: central nervous system IHC: immunohistochemistry MMR: mismatch repair MTS: Muir-Torre syndrome M uir-Torre syndrome (MTS) is an autosomal-dominant variant of Lynch hereditary cancer syndrome. MTS is defined by sebaceous neoplasms occurring in association with 1 or more internal malignancies. The sebaceous neoplasms that characterize MTS are rare among the general population and include seb...
AIMS Regulation of cell cycle progression is a fundamental control process, linked to cellular differentiation and apoptosis in normal tissues. p21(WAF1) is a nuclear protein that regulates cell cycle progression. p21(WAF1) can be transcriptionally upregulated by p53, but may be activated independently of p53-for example, during terminal differentiation. Loss of topological control of p21(WAF1)...
