Three opportunistic infections associated with ectopic corticotropin syndrome

Cytomegalovirus pneumonia, Pneumocystis carinii pneumonia, and pulmonary and disseminated aspergillosis occurred simultaneously in a 66-year-old white man with oat cell carcinoma and ectopic corticotropin production. Hypokalemia, a recent normal chest roentgenogram, and a large left adrenal mass on a computed tomographic scan confused the initial clinical evaluation. The aspergillosis proved fulminant and lethal.
