Cutaneous Alternariosis

Abstract

A 37-year-old man has had a skin lesion on his left cheek for twenty five years. After ten years his right cheek also became involved. Alternaria alternata was isolated from the biopsy tissue. The upper and middle parts of the dermis were the site of a granulomatous inflammation. In the granulomatous lesion there were many giant cells containing round spore-like bodies. In PAS-stained sections the walls of spore-like bodies stained positive.
