[Insulated arm pilomatrixoma: A rare localization. A case report].

Pilomatrixoma also known as calcified epithelioma of Malherbe, is a rare benign cutaneous tumor. It is most commonly seen in the head and neck areas, during the first two decades of life. We report a 30-year-old female patient with a rare localisation of pilomatrixoma in the right arm. The pilomatrixoma was excised and at one year follow-up there has been no evidence of recurrence.
