Cutaneous cryptococcosis and histoplasmosis coinfection in a patient with AIDS.

Patients with AIDS may have multiple infections at one time, and skin lesions resulting from simultaneous infections with more than one organism have been described. We report a case of disseminated cryptococcal and histoplasmosis infections with cutaneous lesions in a patient with AIDS. In addition, we demonstrate the first case of two coexisting fungal infections in a unique skin lesion. The cutaneous presentation of infectious disorders in HIV-infected patients is often nondescript and not diagnosed by clinical observation alone. Biopsies and cultures are essential for making accurate diagnoses in immunocompromised patients with unusual skin lesions.
