OBJECTIVETo investigate the clinico-pathologic features, treatment and prognosis of Castleman disease.

METHODSThe clinico-pathologic data of 16 patients diagnosed as Castleman disease from January 2002 to December 2014 were analyzed retrospectively.

RESULTSThe median age was 28.5 (7-73)years old. There were 14 unicentric cases, 92.8% (13/14) of which was diagnosed as hyaline-vascular type. Two multicentric cases was diagnosed as plasmatcyic type. All the patients were treated by surgical resection and their median follow-up was 55.5 (2-150)months. As a result, 13 unicentric cases achieved sustained remission, 1 unicentric case with plasmatocytic type relapsed at 60th month after surgical resection.

CONCLUSIONClinical subtype and histopathogenic type are the dominating progonostic factors in Castleman patients. The clinical presentation of unicentric disease has been found to be benigns and the surgical resection can be used as first-line treatment method in clinic. The clinical presentation of multicentric disease may be stable or advanced, and the prognosis of advanced cases is poor as there are no effective treatments.
