Unusual presentations of primary human immunodeficiency virus infection.

Opportunistic infections during primary infection with human immunodeficiency virus (HIV) are rare, with the exception of oral and esophageal candidiasis. HIV-associated nephropathy (HIVAN) and Pneumocystis carinii pneumonia (PCP) typically occur during advanced HIV infection. We report two patients who developed HIVAN and a presumptive diagnosis of PCP, respectively, during primary HIV infection. Serologic testing demonstrated HIV seroconversion. Clinicians need to have a high index of suspicion when evaluating patients even when risk behaviors are not readily apparent.
