Pilomatrixoma: Osservazione di un caso

Pilomatrixoma (Malherbe's calcifying epithelioma) is a benign tumor that arises from the matrix of hair follicles. It has the propensity to occur in the head region and often involves the eyelid or eyebrow. Although pilomatrixoma is well known to dermatologists and ophthalmologists, it is not widely recognized among otolaryngologists as a cause of a solitary, round, firm, intradermal nodule in head skin in a child. We report the findings in a 5-year-old child who developed a single pilomatrixoma of the right upper eyebrow.
