Pilomatricoma of the pinna.
A 4-year-old boy presented with a painless swelling over the right pinna of 4 months' duration. Histopathologic examination of the excised mass revealed features of pilomatricoma-a rare, benign skin neoplasm arising from hair follicle matrix cells. The unusual location of the lesion over the pinna, despite its frequent occurrence in the head and neck, prompted this article. We discuss the etiology, clinical presentation, and management of pilomatricoma of the auricular region.
