title: Castleman's Disease Presenting in the Pelvis.
abstract: Castleman's disease (CD) is a rare benign lymphoid disorder with unknown etiology. There are 2 major forms of this disease, unicentric (ie, localized CD) and multicentric, which play a major role in determining therapy. The mediastinum is the most common localization for the localized CD, whereas its occurrence in the pelvis is even rarer. We report the case of a 22-year-old woman who had a pelvic mass located in the region of the left iliac fossa. The patient subsequently underwent a robotic-assisted laparoscopic tumorectomy. Pathological examination revealed pelvic localized CD of the hyaline-vascular type. CD should be included in the differential diagnosis of pelvic masses that are noted in the pelvic cavity.
