Hair Follicle Neoplasms – Pilar Sheath Acanthoma

Pilar Sheath Acanthomas are clinically identical to Dilated Pores of Winer and I occasionally encounter them in both my The Woodlands dermatology and Conroe dermatology offices.  Clinically, a Pilar Sheath Acanthoma appears as a dilated pore and is most commonly found on the face.  The only difference between a Pilar Sheath Acanthoma and a Dilated Pore of Winer is histologically, in that a Pilar Sheath Acanthoma has large lobules radiating from the central pore into the dermis.  As a Pilar Sheath Acanthoma is benign, it does not require treatment unless cosmetically desired.  Removal can be accomplished through a small punch biopsy (2mm) and the defect closed with a small suture.
