[Systemic cryptococcosis and pneumocystosis in an HIV-positive patient].

Cryptococcosis is one of the most common opportunistic infections in AIDS patients. Neurological symptoms are the most frequent clinical presentation of this fungal infection, and pulmonary involvement is clinically much less evident. We report the case of a patient who was treated in the emergency room for acute respiratory failure but who did not survive. Microbiologic and histopathologic studies demonstrated simultaneous pulmonary infections with Cryptococcus neoformans and Pneumocystis carinii. We discuss this clinical presentation of cryptococcosis with no neurological manifestations, and the importance of concurrent infections by several opportunistic organisms that may go unrecognized.
