Epstein-Barr virus associated multicentric Castleman's disease disguised as infectious mononucleosis.

Castleman's disease (CD), also called angiofollicular lymphoid hyperplasia, is a rare lymphoproliferative illness with two unique variants: unicentric disease and multicentric disease (MCD). The multicentric variant is rare and presents as a systemic illness with symptoms like peripheral lymphadenopathy, splenomegaly, anaemia and systemic inflammatory symptoms. Given the vague and systemic presentation, this variant can be difficult to differentiate from infection and other autoimmune diseases.
