Castleman disease (CD) also called as angiofollicular hyperplasia or giant lymph node hyperplasia of unknown cause is a benign lymphoproliferative disorder. It is a localised (unicentric) or disseminated (multicentric) disease. This disease is uncommon with an incidence of 25 cases per million person per year. Castleman disease is a heterogeneous group of disorders with four characteristic histological variants. The etiology of this disease is poorly understood.We report two cases of CD, one presenting with a neck mass and the other presenting with para-aortic and mesenteric lymphadenopathy which were classified as hyaline vascular type and mixed type of CD respectively.
