“…In these cases, any attempt to resect all neoplastic lesions must be done. In non-resectable disease, some authors have employed different non-standardized chemotherapy schemes obtaining variable results [3], [12]. Multimodality therapy has also been tested to rescue patients with disseminated disease.…”

“…Within the abdomen but outside the gastrointestinal tract, leiomyosarcomas occur mainly in the retroperitoneum and greater omentum 67–69 and, less commonly, in the inferior vena cava 70 . Similarly, liposarcoma is most commonly seen in the retroperitoneum, 71–74 though these tumours have also been described in the greater omentum, 75 , 76 oesophagus, 77 small intestine, 78 and in hernial sacs 79 .…”

Intra-abdominal spindle cell lesions are uncommon and often present a diagnostic challenge. An important group of such lesions are the gastrointestinal stromal tumours. Other intra-abdominal spindle cell lesions include fibromatosis, various sarcomas-in particular, leiomyosarcoma, liposarcoma, and malignant peripheral nerve sheath tumour-and, in women, endometrial stromal sarcoma. Less common lesions are inflammatory myofibroblastic tumours, the mesenteric spindle cell reactive lesions, retroperitoneal fibrosis, and solitary fibrous tumour. A variety of intra-abdominal tumours of nonmesenchymal origin may have a spindle cell/sarcomatoid morphology; these include sarcomatoid carcinoma, malignant melanoma and, in women, sarcomatoid granulosa cell tumour. Finally, metastatic sarcomas from pelvic or extra-abdominal organs need also be considered. A set of practical aids to the diagnosis of intra-abdominal spindle cell lesions is presented to assist pathologists dealing with such lesions, particularly with regards to the consideration of differential diagnoses.

“…Omental tumors are commonly observed in leiomyosarcoma, hemangiopericytoma, and fibrosarcoma, but liposarcoma occurs in only 1 % of patients [6]. Some studies report that primary omental tumors are most common in men aged 50-60 years [7,8]. Primary liposarcoma of the omentum is not associated with any specific symptoms and, therefore, diagnosis and management is often delayed.…”

Primary omental pleomorphic liposarcoma identified at autopsy in a living donor kidney transplant recipient

et al. 2012

Metastatic and recurrent tumors of the omentum are common, but primary omental pleomorphic liposarcoma (POPL) is an extremely rare type of solid omental tumor. We describe the case of a patient with POPL who received a renal transplant from a living donor. Despite good allograft function, the volume of peritoneal fluid gradually increased. An exploratory laparotomy could not be performed because the patient was obese and developed hemodynamic instability. Therefore, a shunt was placed between the peritoneal cavity and the internal jugular vein using the Denver Ò shunt system; however, the patient died of respiratory insufficiency. On the basis of the autopsy results, we diagnosed the patient's condition as POPL. We speculated that the malignancy did not originate directly from the donor cells. We report POPL in a living donor renal transplant recipient.
