Sebaceous neoplasms in Lynch syndrome
Background Sebaceous neoplasms of the skin (SN) are described in the Muir Torre variant of Lynch syndrome (LS). Guidelines recommend evaluating individuals diagnosed with sebaceous adenomas or sebaceous carcinomas for LS with immunohistochemistry (IHC) for mismatch repair (MMR) proteins and/or microsatellite instability analysis (MSI). The assumption has been that SNs with defective MMR are rel...
متن کاملCystic sebaceous neoplasms in Muir-Torre syndrome.
Cystic sebaceous neoplasms have been seen only in patients with Muir-Torre syndrome (MTS) and have recently been characterized as marker lesions of MTS. Histologically, these lesions form a spectrum of tumors ranging from benign cystic adenomas to proliferative cystic sebaceous tumors. We describe 2 proliferative cystic sebaceous tumors in a 53-year-old man whose workup revealed colonic adenoca...
متن کاملSebaceoma and Related Neoplasms With Sebaceous Differentiation
The classification of benign sebaceous neoplasms has been challenged both by the assertion that sebaceous adenomas are really carcinomas and by difficulties in drawing the boundaries between sebaceomas and other lesions. We performed a clinicopathologic study of 30 cases of basaloid neoplasms with sebaceous differentiation, excluding cases of definite sebaceous carcinoma with severe nuclear aty...
متن کاملDiagnosing Lynch syndrome
R isk stratification is essential for designing efficacious and cost effective colon cancer screening programmes. One of the most important risk factors for colorectal cancers (CRC) is an inherited predisposition, implicated in 20% of all cases. The spectrum of genetic susceptibility ranges from the low penetrance mutations that modestly increase the colon cancer risk (for example, I 1307K) to ...
متن کاملLynch syndrome (HNPCC)
Lynch syndrome, also referred to as hereditary non-polyposis colorectal cancer (HNPCC), accounts for somewhere between 2 and 5% of all CRC. It has been shown that Lynch syndrome (LS) is a result of germline mutations in genes involved in DNA mismatch repair (MMR) MSH2, MLH1, MSH6, and PMS2, whereas as HNPCC refers to families that adhere to the Amsterdam criteria or iterations of it. More recen...
