Castleman disease is a rare disorder that involves an overgrowth (proliferation) of cells in your body's disease-fighting network (lymphatic system). Also known as giant lymph node hyperplasia and angiofollicular lymph node hyperplasia, Castleman disease can occur in a localized (unicentric) or widespread (multicentric) form.
Fever. Night sweats. Fatigue and weakness. Loss of appetite. Unintended weight loss. Enlarged lymph nodes, usually around the neck, collarbone, underarm and groin areas. Enlarged liver or spleen.
A hyaline vascular variant (HVV) with local LN involvement was diagnosed in 38 (50%) patients; a plasma cell variant (PCV) was in 38 (50%); among the latter, 17 (22%) patients were found to have local involvement and 21 (28%) had generalized (multicentriC) involvement (multicentric Castleman's diseases (MCD)). Five (24%) patients with MCD were established to be infected with human herpesvirus type 8 (HHV-8). HVV was more frequently diagnosed in women (4%) than in men (29%); PCV was equally common in both men (47%) and women (53%); MCD was statistically significantly more frequently encountered in men (86%) than in women (14%) (p=0.05).
