A Rare Retroperitoneal Benign Tumor

Abstract

A case of retroperitoneal Castleman’s disease – a benign lymphoid tumor – is reported. The tumor is excised totally. A 34-month follow-up period is disease free and uneventful. The preoperative workup presented, its clinical behavior and management are discussed.

Laparoscopic Resection of Nonadrenal Retroperitoneal Tumors

“…We excluded patients who had tumors larger than 10 cm or features of malignancy, such as the presence of irregular margins and definite invasion to adjacent organs based on preoperative radiologic findings. Even for patients without symptoms, laparoscopic excision was used because of the possibility of misdiagnosis [17][18][19] and malignant transformation. 19,20 We retrospectively analyzed the clinical outcomes of 20 patients who underwent laparoscopic excision of a primary nonadrenal retroperitoneal tumor.…”

The clinical outcomes, including operative time, estimated blood loss, postoperative hospital stay, and complications, were evaluated with respect to tumor size and adhesions to adjacent major vessels.…”
