Abstract

Dilated pore was originally designated as a secondary or acquired trichoepithelioma by Winer, represents an appendageal tumor with differentiation towards hair structures. It is clinically characterized by having the appearance of a large blackhead filled with keratinous material. To the best of our knowledge, there has been no report of a dilated pore with four openings. We herein describe such a case.
