Thrombocytopenia is a frequent hematologic complication in advanced HIV/AIDS, presenting significant diagnostic challenges due to overlapping etiologies. Hemophagocytic lymphohistiocytosis (HLH), immune reconstitution inflammatory syndrome (IRIS), and HIV-associated immune thrombocytopenic purpura (HIV-ITP) can all manifest with overlapping clinical features, which, despite their differing frequencies, may complicate diagnosis and management. We present a case of a 33-year-old male patient with advanced HIV/AIDS, metastatic Kaposi sarcoma, and inconsistent antiretroviral therapy (ART) adherence, who developed progressive thrombocytopenia, anemia, and pancytopenia.
