The association between multiple pilomatrixomas and APC gene mutations

Abstract

Dear Editor, Familial adenomatous polyposis is an autosomal dominant disorder caused by a germline mutation of the tumour suppressor gene adenomatous polyposis coli (APC) located on chromosome 5q22.2. Familial adenomatous polyposis is characterized by the development of hundreds of polyps in the colorectum, typically beginning in the second or third decade of life and eventually progressing to colorectal cancer in nearly all individuals if left untreated.
