Disseminated histoplasmosis associated with the acquired immune deficiency syndrome

Disseminated histoplasmosis developed in a previously healthy man as the initial manifestation of the acquired immune deficiency syndrome. Following apparently successful therapy with intravenous amphotericin B, he presented two months later with a subacute pneumonitis syndrome diagnosed by bronchoscopy as Pneumocystis carinii pneumonia. He showed response to intravenous trimethoprim/sulfamethoxazole with resolution of his symptoms and clearing of chest radiographic findings. While he was receiving antibiotics, oral candidiasis developed and has persisted for more than two months despite topical therapy and discontinuation of all antibiotics.
