Surgical resection for pelvic retroperitoneal Castleman's disease: A case report and review literature

Castleman's disease (CD) is a rare atypical lymphoproliferation disorder first reported in 1954. Clinically, CD is classified as unicentric or multicentric CD based on anatomical distribution. Unicentric CD primarily affects the mediastinum, and rarely affects the retroperitoneal location. The standard treatment for unicentric CD is complete surgical resection; however, this can be complicated by a high degree of attachment with other organs or hypervascularity. Preoperative angiography and embolization of the arteries that feed the problematic mass can reduce intraoperative bleeding in cases of CD with hypervascularity. In the present case report, a 44-year-old man who was found to have a pelvic retroperitoneal mass with calcification based on abdominal imaging results is discussed. Due to the hypervascularity of the mass, preoperative embolization was performed. The mass was completely resected without any complications. Additionally, a review of the literature on pelvic CD and preoperative embolization of CD was performed to provide an up-to-date reference on the management and outcomes of patients with CD.
