A Case of Stucco Keratosis / 대한피부과학회지

ABSTRACT

Stucco keratosis is a clinically distinct variant of seborrheic keratosis, which presents exclusively on the lower legs as white-gray keratotic warty papules. When the lesion is removed, a peripheral collarette of scale remains without bleeding. We report a case of stucco keratosis on the dorsum of the feet and ankles of a 79-year old man. Pathologic findings showed characteristic epidermal hyperplasia of the "church spire" pattern with basket-weave hyperkeratosis. He was treated with topical urea and lactic acid for 2 months and showed improvement.
