title: Hyaline vascular castleman disease involving renal parenchyma and a lymph node: a case report.
abstract: Castleman disease is a rare lymphoproliferative lesion that is predominantly found in the mediastinum. Retroperitoneal and pararenal localizations are very rare. We describe a 36-year-old man with a hyaline vascular type of Castleman disease involving renal parenchyma and a paraaortic lymph node. Most reported renal Castleman disease was plasma cell type with systemic symptoms. Herein, we report the first Korean case of the hyaline vascular type of Castleman disease involving the renal parenchyma and the paraaortic lymph node simultaneously.
