Multiple pilomatricoma with perforation

A 22‐year‐old woman presented to our clinic with a complaint of masses on various parts of her body. A mass on her right forearm had appeared 5 years ago and had enlarged during the past 6 months. Two lesions on the back of her neck had a 3‐year history, one lesion on her eyebrow had a 2‐year history, and one lesion on her left forearm had a 1‐year history. The lesion on her left forearm was discharging purulent material. Dermatologic examination revealed a 15 × 16 mm tumor on the right forearm, 11 × 6 mm and 10 × 5 mm tumors on the back of the neck, and a 20 × 20 mm tumor on the eyebrow; they were flesh‐colored, well‐defined, firm tumors. On her left forearm, there was a 12 × 10 mm, well‐defined, firm, blue–red tumor discharging chalky white granules; purulent material was detected ( Fig. 1 ).
