title: Giant peritoneal loose body in the pelvic cavity confirmed by laparoscopic exploration: a case report and review of the literature.
abstract: A 51-year-old previously healthy male underwent a routine medical examination. Computed tomography and ultrasonography showed an oval-shaped mass that was about 50 × 40 mm in size in the left iliac fossa. Prior to surgery, the lesion was suspected to be a teratoma with core calcification or stromal tumor derived from the rectosigmoid colon. During the procedure, a yellow-white, egg-shaped mass was discovered that was completely free from the pelvic cavity in front of the rectum. The giant, peritoneal loose body was taken out through the enlarged port site. Histological examination showed that the mass consisted of well-circumscribed, unencapsulated, paucicellular tissue, with an obviously hyalinized fibrosclerotic center. A giant peritoneal body is extremely rare. We report such a case and review previously published literature.
