Colchicine therapy in amyloidosis related with plasmacytic Castleman disease presenting with nephrotic syndrome.

Castleman disease (CD) is a neoplasm that presents with single or multiple lymphadenopathy. The disease is characterized by fever, weight loss, anemia, polyclonal hyperglobulinemia, splenomegaly, thrombocytosis and peripheral lymphadenopathy. In this paper, we report a young man with plasmacytic type CD and amyloid A (AA) deposition who presented with intra-abdominal mass and nephrotic syndrome. He was successfully treated with colchicine following surgery.
