Pilomatrixoma Recurring as Giant Form

Ana Teresa Tavares et al. Cureus. .

Abstract

Pilomatrixoma is a benign skin tumor that originates from the hair matrix. It usually appears in children and young adults and is preferably in the head and neck region. It clinically presents as an asymptomatic firm, solitary subcutaneous mass of less than 3 cm. When located in the preauricular area, it is often misdiagnosed as benign or malignant parotids, skin tumors, or sebaceous cysts. Its treatment of choice is surgery, and recurrence is due to incomplete excision. We present a case of a male referred to our hospital with a diagnosis of recurrent pilomatrixoma in its giant form. The lesion was fully excised with no signs of recurrence and no functional impairment.

Keywords: diferential diagnosis; giant pilomatrixoma; head and neck surgery; head and neck tumors; pilomatrixoma; recurrent pilomatrixoma; skin adnexal tumor.
