Abstract
Castleman's disease (CD) and thrombotic thrombocytopenic purpura (TTP) are rare diseases that can affect the general population, especially those with HIV. Owing to their rarity, the association between CD and TTP remains insufficiently understood. In this study, we present a case of a 53-year-old patient with controlled HIV infection who presented with fever, lymphadenopathy, severe anaemia, and thrombocytopenia. After a series of tests, the diagnosis was concurrent human herpesvirus 8 (HHV8)-related multicentric CD (MCD) and TTP. Only four male patients were previously reported having this association, with HHV8 present in four and HIV in three patients, suggesting that coinfection with HHV8 and HIV is a pivotal factor in MCD with TTP occurrence.
LEARNING POINTS
Castleman's disease (CD) and thrombotic thrombocytopenic purpura (TTP) are rare diseases, and their association remains extremely uncommon.We report a case of multicentric CD (MCD) with TTP in a 53-year-old male patient with HIV.Only five patients, including ours, have been reported as having both MCD and TTP, with all five having HHV8 and four having HIV. Thus, coinfection with HHV8 and HIV may be a potential pivotal factor in the occurrence of MCD with TTP.
