Giant Liposarcoma of the Omentum Mimicking an Ovarian Tumor. A Case Report

Abstract

Liposarcomas are common soft tissue of the retroperitoneum and the limbs. They are rarely found in the greater omentum. Once in the peritoneum, these can become enormous and can be mistaken for ovarian mass. The authors report a case of giant omental liposarcoma revealed by an abdominal mass and genital prolapse due to the compression syndrome. A complete macroscopic resection of the omental tumour was performed. A post operative chemotherapy was also prescribed. A description of this clinical presentation in the preoperative assessment, the characteristics of this tumour, together with the use of adjuvant chemotherapy are discussed in this report.

Resection of liposarcoma of the greater omentum: A case report and literature review

“…The average age of the patients was 51.1 years (range, 11–83 years). Although our patient was asymptomatic, the patients in previous reports exhibited various symptoms including abdominal pain, swelling, fever [13], constipation [14], and abdominal distention [15]. Cases of liposarcoma of the greater omentum presenting as inguinal hernia and torsion have also been reported [16].…”

Giant mesenteric myxoid liposarcoma: Challenges of diagnosis and treatment

“…It occurs mainly in the deep soft tissues of the limbs (75%), in particular in the thigh, popliteal fossa, and also in the retroperitoneum [8] . Intra-abdominal localization is uncommon.…”

Ultrasonographic findings and diagnosis of omental dedifferentiated liposarcoma: a case report

“…To our knowledge, there are only 15 English case reports on omental liposarcoma, including ours [3][4][5][6][7][8][9][10][11][12][13][14] (Table 1). A de-mographic review of these cases showed that the average age was 50.3 years, and 8 out of 14 (57.1%) patients were male.…”
