A 66 years-old male Polynesian farmer visited Apia General Hospital on May 18, 1973, for the granulomatous lesions on his left leg. Fifteen years ago, he suffered a crush wound during work in the plantation of bananas coconuts and taros. The wound healed by medical treatment but soon after he noticed a granulomatous lesion on the site of previous scar tissue. The lesion became gradually enlarged and made cauliflower-like ulcerogranulomatous vegetations with central healing occupying almost entire left leg. KOH-examination of crust and necrotic mass from lesions revealed numerous dark brown. hyphae and spores with septation. Materials from the lesions were cultured on Sabouraud's glucose agar slants containing cycloheximide and chloramphenicol at room temperature and yielded a slow growing, dark brown to greyish, flat colony with short aerial hyphae on its surface. Microscopically, Cladosporium-type (Hormodendrum-type) sporulatoin was recognized and the fungus was identified as Phialophora pedrosoi. This will be the first chromomycosis case reported from South Pacific islands.
