Disseminated histoplasmosis in an immunosuppressed patient.

A renal transplant recipient was receiving prednisone and azathioprine therapy when he developed fever, cough, and erythema-nodosum-like lesions on the extremities. Disseminated histoplasmosis was diagnosed by skin biopsy. Disseminated histoplasmosis should be considered when a patient under immunosuppressive therapy develops a lesion similar to erythema nodosum or erysipelas with panniculitis.
