Cutaneous blastomycosis presenting as non-healing ulcer and responding to oral ketoconazole

Abstract

Primary cutaneous blastomycosis is a rare infection of the skin that usually follows trauma and presents as a papule or nodule that ulcerates. Although this infection often heals spontaneously, we present a case of a nonhealing ulcer following surgical drainage of cellulitis. Blastomycosis was diagnosed by histopathological examination and the infection responded well to oral ketoconazole therapy.
