Abstract

Pilomatricoma is a relatively uncommon benign skin neoplasm, probably derived from matrical cells of the hair follicle. They most commonly appear in childhood or adolescence, but may also occur in adults and frequently present as isolated asymptomatic papules or nodules that occur on the head, neck, or upper extremities. The histopathologic findings of pilomatricomas are distinctive. A well-demarcated cyst-like structure containing peripheral small, basophilic cells and central eosinophilic keratinized cells is located in the lower dermis and may extend into the subcutaneous fat. Surgical excision is generally recommended for pilomatricomas, to prevent growth or cosmetic disfigurement.
