Pilomatricoma of the elbow

Abstract

Pilomatricoma is a common benign skin tumor of follicular origin, occurring mainly in the head and neck region. However, less common locations, such as the arm or elbow, can also be observed. Definitive diagnosis is based on histopathological examination, and standard treatment consists of complete surgical excision of the lesion. We report the case of a 31-year-old man with a pilomatricoma located on the posterolateral aspect of the right elbow, which had been evolving for 2 years. After surgical excision under locoregional anesthesia followed by thin skin grafting, no signs of local recurrence were observed after 12 months' follow-up. This case is particularly interesting because of the rare location and large size of the tumor in the elbow.
