Atypical Pneumocystis carinii infection in AIDS: massive cervical lymphadenitis and fever of unknown origin.

Pulmonary Pneumocystis carinii infections are relatively common in patients with the acquired immunodeficiency syndrome (AIDS). Extrapulmonary pneumocystis is a less common manifestation, particularly when it occurs without concurrent Pneumocystis carinii pneumonia. Disseminated pneumocystis is most commonly found in lymph nodes, the liver, and the spleen and may result in nonspecific debilitating illness, which is often overlooked in the absence of pulmonary symptoms. We present the case of an AIDS patient who had massive cervical pneumocystis lymphadenitis and minimal pulmonary infiltrates of undetermined etiology and a clinical picture of severe wasting and fever of unknown origin.
