“… Ishida and Ishida (1998) stated it to be the imaging of choice for greater omental tumors. A gastro-colic separation resulting from a tumor in the omentum can sometimes be seen ( Fattar et al, 1981 ) and their CT appearance is usually multilobulated, flat, and pancake-like, with enhancing solid and multicystic densities. However, in this case the presentation, US and CT diagnosis were suspected to represent ovarian carcinoma.…”

“…Angiography was described as useful in the diagnosis of greater omental tumors ( Dixon et al, 1984 , Fattar et al, 1981 , Ishida et al, 1999 Mar ). A diagnosis of a greater omental tumor can be suspected when a feeding artery to the tumor originates from the omental blood supply.…”

“…Leiomyosarcoma is but one of many greater omental tumors. Reported primary tumors of the omentum, include leiomyosarcoma, fibrosarcoma, hemangiopericytoma, spindle cell sarcoma, liposarcoma, leiomyoma, lipoma, desmoid tumor, fibroma, mesothelioma, and others ( Fattar et al, 1981 , Ishida et al, 1999 Mar , Stout et al, 1963 , Weinberger and Ahmed, 1997 ) They derive from different elements in the greater omentum which is composed mainly of fat but contains various tissues- such as vessels and lymphatics. Nevertheless, all of these primary omental tumors are very rare.…”

Primary omental leiomyosarcoma is a rare tumor. We report a case of successfully resected omental leiomyosarcoma whose presentation mimicked ovarian carcinoma. Symptoms of abdominal distension and discomfort that lasted 8 months followed by pain lead to a diagnosis of a large mass in the abdomen. Physical examination revealed a large, over 20 cm tumor, suspected to be of ovarian origin. A small amount of ascites was found on Computerized Tomography (CT) and ultrasound (US) scans. Total abdominal hysterectomy with bilateral salpingo-oophorectomy, omentectomy and tumor debulking procedure was planned. Laparotomy revealed normal uterus ovaries and tubes with a leiomyosarcoma of the omentum which was completely resected successfully. Only 26 cases of primary leiomyosarcoma of the omentum were previously described in the literature. A review of the literature is also presented.

“…Moreover, lesser omental leiomyosarcomas are even more infrequent with only three cases being identified using a PubMed search with the keywords “lesser omentum” and “leiomyosarcoma.” However, all three reports did not include c-kit immunostaining, which would help distinguish leiomyosarcoma from GIST [5–7]. The following omental tumors have also been reported: extra-GIST, leiomyosarcoma, fibrosarcoma, hemangiopericytoma, spindle cell sarcoma, liposarcoma, leiomyoma, lipoma, desmoid tumor, fibroma, and mesothelioma [8–12].…”

Background Primary omental leiomyosarcoma is an extremely rare type of tumor. Leiomyosarcomas originating from the lesser omentum have not been reported since immunohistochemical staining for c-kit has been used for the diagnosis of mesenchymal abdominal tumors. They are yet to be reported since gastrointestinal stromal tumors were categorized. Here we reported a case of successful resection of a lesser omental leiomyosarcoma. Case Presentation A 71-year-old man underwent ultrasonography at the outpatient clinic through which an upper abdominal tumor was identified. Following computed tomography and endoscopy, a 4.5 cm submucosal tumor in the lesser curvature of the stomach was highly suspected. A laparoscopic partial resection of the stomach was performed. Histopathological examination revealed the tumor to be a leiomyosarcoma arising from the lesser omentum that did not invade the stomach. Immunohistochemical staining showed that the tumor was negative for CD34, c-kit, and S-100 and positive for desmin and α-smooth muscle actin. No recurrence had been observed 1 year after surgery without adjuvant chemotherapy. Conclusions Primary lesser omental leiomyosarcoma, which is difficult to diagnose before surgery given the location of the primary tumor in the lesser omentum, has rarely been reported. Considering the high possibility of malignancy, close observation is essential.
