Pilometrixoma of the Thigh - A Case Report

Abstract

Pilomatrixoma is a benign skin tumor derived from hair follicle matrix cells. They typically present as a superficial, firm, solitary, slow-growing, painless mass in the dermis. Pilomatricomas are frequently misdiagnosed and are not usually considered in differential diagnoses, either in clinical set-up or during cytological reporting. These lesions are typically found in the head and neck region. Involvement of the lower extremities is relatively uncommon and can be mistaken for malignancy. We present the case of a 55-year-old male with a pilomatrixoma of thigh which is a rare site of occurrence of the lesion and we review the literature regarding pilomatrixomas.
