Abstract:
Castleman disease, or angiofollicular lymph node hyperplasia, is a fairly rare benign tumor of lymphoid origin. Most cases tend to present as a mediastinal mass. We report a 58-year-old man with Castleman disease of the right perirenal space. This case was diagnosed preoperatively as nonconventional renal cell carcinoma (RCC) or renal oncocytoma because the enhancing mass abutted the renal cortex. The patient underwent a radical nephrectomy and a histopathological analysis showed the unicentric plasma cell type of Castleman disease. A preoperative diagnosis of Castleman disease is difficult; therefore, a surgical resection and a histological evaluation can provide an accurate diagnosis of this tumor. Taking this case into consideration, we suggest that Castleman disease should be included in the differential diagnosis of renal tumors.
