Castleman’s disease imitating adrenal mass in the retroperitoneal area

摘要

Castleman’s disease (CD) is a non-clonal lymph node hyperplasia, mostly seen in the mediastinum. It has various clinical and pathological outcomes. There are different treatments because of its rare occurance and heterogenity. We present 2 cases which were referred to our clinic as retroperitoneal mass and diagnosed as CD after surgical resection. Castleman’s disease (CD) is a non-clonal lymph node hyperplasia and was first described in 1956 by Benjamin Castleman and colleagues. 1 It is rare and also known by follicular lymphoreticuloma, angiofollicular lymph node hyperplasia, giant cell lymph node hyperplasia, benign giant lymphoma and lymphoid hamartoma. It has various clinical and pathological outcomes. It is mostly seen in the mediastinum (60%–70%) and less seen in the abdomen (10%–17%). 2 , 3 Masses in the abdomen are generally seen in the retroperitoneum. We describe 2 cases of retroperitoneal mass and diagnosed as CD after surgical resection.
