Disseminated Osteoarticular Sporotrichosis

Abstract

We report a case of multiple skin lesions, lymphadenopathy, and osteoarticular sporotrichosis in a man infected with human immunodeficiency virus (HIV). He subsequently died of tuberculosis after successful treatment for osteoarticular sporotrichosis with amphotericin B. We describe the unusual histopathology in disseminated sporotrichosis with acquired immunodeficiency syndrome (AIDS) and compare it with that seen in patients without AIDS. Although the optimal treatment of osteoarticular sporotrichosis in patients with AIDS is unknown, use of amphotericin B in our patient appeared successful. Culture and histologic stains of all tissues taken at autopsy were negative for sporotrichosis. Recent studies of similar cases have shown initial treatment with amphotericin B followed by long-term maintenance with itraconazole to be beneficial.
