A Case of Acquired Immunodeficiency Syndrome with Pneumocystis Carinii Pneumonia Detected in Health Check-up

We present a case report on a Japanese patient who had acquired immunodeficiency syndrome (AIDS) associated Pneumocystis carinii pneumonia (PCP). The patient was a 39-year-old man who was a former homosexual. He was found to have atypical bilateral pneumonia in a health check-up. PCP was suspected because of his low oxygen saturation, ground-glass opacities in both lung fields, and marked elevation of beta-D-glucan. A diagnosis of PCP was finally established through a polymerase chain reaction (PCR) for the causative pathogen in bronchoalveolar lavage. AIDS was diagnosed by positive HIV antibody. This is the first report of the clinical diagnosis of a case of AIDS associated PCP detected in a health check-up (Ningen Dock).
