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.

Symptomatic giant peritoneal loose body in the pelvic cavity: A case report

“…A giant PLB in particular can cause acute, as well as chronic symptoms like mentioned in the introduction above [5] , [6] , [7] and reported in our own case. Nevertheless, it normally hasn’t got any clinical significance and is detected incidentally at radiological examination, laparoscopy/laparotomy or autopsy [8] .…”

“…Especially its “giant” form (gPLB) with a diameter >5 cm has rarely been described in the literature though this phenomenon has been known for over 300 years [2] , [3] , [4] . Although a gPLB can cause symptoms like abdominal and/or pelvic pain or discomfort with alternating localization [5] , intestinal obstruction [6] or urinary retention [7] , it is mostly detected incidentally at radiological examination, laparoscopy/laparotomy or autopsy [1] . Moreover, it is often misinterpreted as an intraabdominal tumor or foreign body, and overstated surgical procedures are carried out [8] .…”

Giant peritoneal loose body: A case report

“…They are usually located freely in the peritoneal cavity (1) and rarely cause symptoms. PLBs are usually 5-20 mm in diameter and are diagnosed via laparotomy or autopsy by accident (2). Matsubara et al (3) reviewed 20 reported PLB cases and determined that PLB is more common in males, with a male:female ratio of 17:3.…”

Laparoscopic extraction of a giant peritoneal loose body: Case report and review of literature

“…Giant PLBs measuring more than 5 cm are very rare, and only a few cases have been reported. A literature search found 20 cases of giant PLBs ( Table 1 ) [1] , [2] , [4] , [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] , [15] , [16] , [17] , [18] , [19] , [20] , [21] . Interestingly, as in our case, most giant PLBs occurred in men over age 50; three female cases were reported.…”
