The authors present a case report of 59-years-old woman examined for pancytopenia recently diagnosed during hospitalization for bilateral interstitial pneumonia without any confirmed etiological agents. Concomitantly, some systemic symptoms like lack of appetite and weight loss were present. Primary hematological disease was ruled out. Positivity of serological screening for HIV-1,2 was rather surprising. Absolute count of CD4+ lymphocytes was 8/μl. Thus, HIV infection was already in stage of AIDS and retrospectively, the interstitial pneumonia has to be judged as AIDS-indicative illness.
Keywords: HIV; interstitial pneumonia; pancytopenia.
