Abstract:
Pilomatricoma, also known as calcifying epithelioma of Malherbe, is a benign adnexal skin tumor arising from hair matrix cells. Clinically, pilomatricoma typically presents as a firm, bluish or red colored, deep-seated nodule with overlying normal skin. Several variants of pilomatricoma have been described including perforating, extruding, bullous, melanocytic, giant, keratoacanthoma-like, exophytic, lymphangiectatic, familial, anetodermic, and multiple. Among these, an extruding variant has been very rarely reported. A 10-year-old girl presented with a 2-month history of a rapid-growing, solitary, firm, skin-colored to pinkish, pedunculated papule with a central crusted perforation on the left cheek. Based on the clinical and histological findings, we made a diagnosis of exophytic pilomatricoma with perforating figure. She had no signs of recurrence of the lesion for 8 months after removal.
