title: A case of multicentric Castleman's disease associated with renal amyloidosis and pure red cell aplasia.
abstract: This is the first reported case of multicentric Castleman's disease (MCD) associated with renal amyloidosis and pure red cell aplasia (PRCA). Inguinal lymph node biopsy showed follicular hyperplasia with prominent germinal centers and plasma cell proliferation in the interfollicular areas. Renal biopsy specimens revealed intraglomerular amyloid deposits, defined as AA amyloidosis. Since amyloid deposits were not present in the gastric and rectal mucosal tissues, his renal disorder was found to be an unusual secondary amyloidosis associated with MCD. Following treatment by plasma exchange, there was progressive deterioration of anemia due to PRCA detected by bone marrow aspiration. Subsequently he was successfully treated with steroid pulse therapy not only for anemia but also for renal function.
