The case of a 45-year-old man with HIV disease with bulky lymphadenopathy, fevers, and weight loss is presented. Immune reconstitution inflammatory syndrome was initially believed to be the cause, but the patient was found to suffer from Kaposi sarcoma, multicentric Castleman disease, hemophagocytic syndrome, and a newly described lymphoproliferative disorder. The diagnostic reasoning related to the causes of the fulminant illness is discussed as well as the roles of Epstein-Barr virus, human herpesvirus 8, and hepatitis C virus in the patient's clinical presentation and the therapeutic choices.

This study retrospectively evaluated the computed tomography (CT) findings of idiopathic multicentric Castleman disease (iMCD) at a single center and compared the CT findings of iMCD-TAFRO with those of iMCD-non-TAFRO. CT images obtained within 30 days before diagnostic confirmation were reviewed for 20 patients with iMCD (8 men and 12 women, mean age 52.8 ± 12.

The majority of multicentric Castleman disease (MCD) patients in China are of the idiopathic subtype (iMCD) with systemic manifestations. However, the impact of iMCD on life quality, mental and psychological status, social function, and caregiving burden is poorly understood. To address this gap, a cross-sectional web-based survey was conducted with 178 iMCD patients and 82 caregivers, including 42 patient-caregiver dyads.

A risk-stratified treatment approach to MCD based on Rituximab immunotherapy for mild cases and chemo-immunotherapy for severe cases has been shown to yield excellent outcomes in PLWH. In contrast, HLH disease, previously known as secondary HLH, has a dismal prognosis even when promptly treated according to guidelines.

Interleukin (IL)-6 and other cytokines play a major role in mediating CD inflammatory manifestations. Although the local microenvironment seems to be among the major sources of hypercytokinemia, the precise cellular origin of IL-6 production in CD is still debated.
