Diagnosis: Pilomatrixoma

Pilomatrixoma is an uncommon benign skin tumor that arises in the dermis or subcutaneous tissue. Growth of abnormally located epidermal elements after birth has been implicated in its development. Pilomatrixoma commonly occurs in the neck and face region, with a female predominance.1The age at onset is bimodal: the first peak occurs during the first 2 decades of life and the second peak between the sixth and seventh decades.2
