TLDR A young woman had a rare scalp tumor usually found in older women.
Proliferating trichilemmal cyst (PTC) was a rare benign tumor derived from the outer root sheath of anagen hair follicles, typically presenting as a lobulated mass on the scalp of elderly women. Histologically, it featured multiple lobules of squamous epithelium with abrupt keratinization and calcification. PTC could be associated with conditions like sebaceous nevus of Jadassohn and spindle cell carcinoma. This document reported an unusual case of PTC with trichoepitheliomatous change in a young woman, highlighting a deviation from the typical demographic and presentation.
