Abstract
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
IntroductionPilomatricomas are superficial, rare, benign skin tumors typically located in the head and neck region. Excluding lymph nodes and epidermoid cysts, they are the next most commonly excised superficial masses in children.1 However, the pinna is an uncommon location for this condition, and hence it is frequently misdiagnosed by otolaryngologists.
