title: An Unusual Location of a Pilar Sheath Acanthoma.
abstract: Pilar sheath acanthoma is a rare, benign follicular hamartoma. Mehregan and Brownstein fist reported this solitary, asymptomatic, and skin-colored nodule with a central pore-like opening in 1978. The classic location for these lesions is the upper lip of elderly patients. Here we report an interesting case of a pilar sheath acanthoma presenting on the left eyebrow in a middle-aged female. To our knowledge, this is the first reported case of a pilar sheath acanthoma in such a unique location.
