Simultaneous multiple pilomatrixomas.

We report a 10-year-old girl with synchronous multiple pilomatrixomas. Pilomatrixomas are generally solitary tumors; synchronous multiple tumors are very rare. Multiple or recurring tumors may be found in association with various syndromes, and multiple tumors may be familial. Concurrent disorders were not identified in our patient and the etiology of her pilomatrixomas was not understood. Thorough examination of the patient and long-term follow-up are necessary with these tumors.
