Proliferating pilar tumor (PPT) is a rare neoplasm arising from the isthmus of the outer root sheath of the hair follicle, commonly called a proliferating trichilemmal cyst. It is described as a well-circumscribed dermal or subcutaneous neoplasm with squamoid cytologic features and trichilemmal type of keratinization. PPTs most commonly occur on the scalp during the 4 th -8 th decades of life with distinct predilection for women. They typically undergo slow but progressive enlargement over several months to years, yielding lobulated and exophytic masses that occasionally ulcerate mimicking squamous cell carcinoma both grossly and microscopically; posing a diagnostic challenge to young surgeons, dermatologists, and pathologists. Here we report an interesting case of an ulcerated PPT which was diagnosed cytologically as benign adnexal tumor and confirmed histopathologically as benign PPT. Ulcerated PPT is an important differential diagnosis of ulcerated scalp swellings and needs to be differentiated from squamous cell carcinoma.
