Simultaneous diagnosis of cryptogenic organizing pneumonia and HIV in a 45 year old man
Organizing pneumonia (OP) may be secondary to many clinical settings, including various infections, drugs, radiation therapy, malignant diseases, and connective tissue diseases. The concomitant occurrence of OP with human immunodeficiency virus infection has rarely been described. Recently, we encountered a case of OP confirmed by surgical lung biopsy in a patient with newly diagnosed AIDS. This case is the first in Korea and the second worldwide in which the diagnoses of OP and AIDS were made simultaneously. In this case, other possibilities that lead to OP, such as drug toxicity, were ruled out carefully.
