Abstract
- Pilar sheath acanthoma is one of the benign follicular hamartoma, with a level of differentiation between trichofolliculoma and dilated pore of Winer. It differentiates toward infundibulum, isthmus, and rarely, sebaceous duct, apocrine, inner root sheath, and hair bulb components. It is a dome-shaped, symmetrical, sharply-circumscribed neoplasm that measures about 1cm in diameter. We herein report a case of pilar sheath acanthoma on the forehead of a 62-year-old male patient.
