title: The dilated pore of Winer--an overlooked cutaneous lesion of cats.
abstract: A retrospective study of 125 cutaneous cystic lesions in cats from 1978 to 1987 Revealed 14 examples of the dilated pore of Winer, a lesion previously described in man and in one cat. Histologically, this lesion appears as a flasklike cystic structure with a wide external opening and laminated keratinaceous content. The cyst is characterized by a thickened wall with numerous, closely apposed rete ridges, either at its base or throughout most of the circumference, with a thinner atrophic wall approaching the os. Clinically, the lesion is a hairless nodule or visible cutaneous defect containing either soft keratinaceous material or, more commonly, projections of horn-like material. In man, the lesion is believed to be either a hamartoma or a benign neoplastic process. Surgical excision is curative.
