“…Usually, the tumor is eventually detected by endoscopy or on radiologic images. 3,5,6 The spontaneous rupture of a GIST is a very rare clinical manifestation, and to our knowledge the rupture of a colonic GIST associated with pneumoretroperitoneum has not been described previously. We report a case of spontaneous rupture of a sigmoid colonic GIST with pneumoretroperitoneum in a 77-year-old woman.…”

Colonic gastrointestinal stromal tumors (GISTs) account for only 5%-10% of tumors arising in the digestive tract. Spontaneous rupture is a very rare manifestation of a GIST; however, we report what to our knowledge is the first documented case of pneumoretroperitoneum caused by the rupture of a GIST. A 77-year-old woman was admitted to our hospital with acute abdominal pain and hematochezia. Colonoscopy showed luminal narrowing in the sigmoid colon, but no definite mucosal defect. Computed tomography (CT) showed an air-containing heterogeneous mass, 9.7 × 9.3 cm, in the pelvic cavity and a small amount of air in the retroperitoneum. Emergency laparotomy revealed a ruptured sigmoid colonic GIST with localized peritonitis. Pathologic examination confirmed that the tumor was composed mainly of round epithelioid cells. It was immunohistochemically positive for CD34 and negative for C-kit protein. This report describes how we successfully managed pneumoretroperitoneum with localized peritonitis caused by the spontaneous rupture of an epithelioid GIST originating from the sigmoid colon.

Clinicopathological features and prognosis of omental GISTs are limited due to the extremely rare incidence. Therefore, the aim of the present study was to investigate the clinicopathological features and prognosis of omental GISTs. Omental GISTs cases were obtained from our center and from case reports and clinical studies extracted from MEDLINE. Clinicopathological features and survivals were analyzed. A total of 99 cases of omental GISTs were enrolled in the present study. Omental GISTs occurred predominantly in greater omentum (78/99, 78.8%). The majority of tumors exceeded 10 cm in diameter (67/98, 68.3%) and were high risk (88/96, 91.7%). Histological type was correlated with tumor location and mutational status. The five year DFS and DSS was 86.3% and 80.6%, respectively. Mitotic index was risk factor for prognosis of omental GISTs. Prognosis of omental GISTs was worse than that of gastric GISTs by Kaplan-Meier analysis. However, multivariate analysis showed that the prognosis was comparable between the two groups. The majority of omental GISTs were large and high risk. Mitotic index was risk factor for prognosis of omental GISTs. The prognosis was comparable between omental and gastric GISTs.

“…Despite the use of advanced radiological imaging techniques, it is difficult to differentiate a GIST in the lesser omentum from that in the lesser curvature of the stomach. As Table 1 shows, four cases of GIST of the lesser omentum, including our case, were misdiagnosed as extramucosal tumors of the stomach [3–5]. Additionally, two cases of GIST of the lesser omentum were followed up as a diagnosis of benign hepatic tumor without surgery [6, 7].…”

A 72-year-old woman visited our hospital for a routine health examination and underwent abdominal ultrasonography, which revealed an intra-abdominal tumor. Abdominal computed tomography and magnetic resonance imaging showed a well-defined solid mass of ~3 cm in diameter lying adjacent to the stomach. The mass was preoperatively diagnosed as gastrointestinal stromal tumor of the stomach. At laparotomy, a well-encapsulated tumor was found in the lesser omentum. It was slightly adherent to the stomach wall but was removed without difficulty. Therefore, only enucleation of the tumor was performed. The excised tumor, which was 35 × 30 × 25 mm3 in size, had a white cut surface without necrosis or hemorrhage. According to the pathological findings, the tumor was classified as a very low-risk gastrointestinal stromal tumor originating in the lesser omentum. Gastrointestinal stromal tumor of the lesser omentum is very rare, and surgical resection is the only effective treatment modality.
