Disseminated, nonmeningeal gastrointestinal cryptococcal infection in an HIV-negative patient.

Gastrointestinal cryptococcosis is extremely rare, especially in patients with no involvement of the central nervous system. We describe a 63-yr-old man undergoing prednisone therapy for chronic hepatitis and cirrhosis who presented with peritonitis, colitis, and skin lesions. Pathological studies revealed necrosis and numerous cryptococcal organisms in the colon, omentum, and skin, and cultures yielded Cryptococcus neoformans. The patient died of multisystem organ failure following emergency exploratory surgery performed when he had onset of symptoms of a bowel perforation after an endoscopic biopsy. Clinicians should be aware that gastrointestinal cryptococcosis can occur in the absence of infection of the central nervous system or lungs, and that it may affect relatively healthy patients who are immunocompromised because of splenectomy, chronic liver disease, or steroid therapy.
