A 25-Year History of Leg Ulceration: Cutaneous Blastomycosis

Abstract

Blastomycosis is a fungal infection caused by Blastomyces dermatitidis. It is characterized by a chronic granulomatous and suppurative inflammatory reaction [1]. Cutaneous blastomycosis (CB) usually develops after hematogenous dissemination from primary lung involvement. However, less commonly, Blastomyces dermatitidis can be inoculated into the skin, causing primary cutaneous blastomycosis. The skin involvement in CB includes a wide variety of manifestations ranging from papulopustular and nodular lesions to verrucous and ulcerative lesions [2]. We report a case of CB initially misdiagnosed as pyoderma gangrenosum (PG)
