“…Leiomyosarcomas are the most frequent, whereas tumors originating from neurogenic fibers, fibrous tissue, blood vessels, and fat are only rarely reported [2][3][4]. Although microscopic features resembling those of liposarcoma may occasionally occur in epithelioid leiomyosarcomas [4], the finding of a real gastric liposarcoma is exceptional.…”

“…The tumor occurs most frequently in the limbs, retroperitoneum, and trunk; visceral locations are only rarely represented, although primary liposarcoma may occur anywhere adipose tissue is found [1]. Only a few cases of gastric primary localizations have been reported [2,3], and none, to our knowledge, in the most recent radiologic literature.We describe herein the clinical and computed tomographic (CT) findings of a patient with pathologically proven gastric liposarcoma. …”

Liposarcoma is the most common malignant mesenchymal neoplasm affecting soft tissues and, less frequently, viscera. Gastric localisation of liposarcoma is extremely rare. We present the case of a 69-year-old female patient, who underwent subtotal gastrectomy with processing of the specimen in the Clinical Service of Pathology, Emergency County Hospital of Constantza. Histopathologically, the tumor exhibits a neoplastic population composed predominantly of lipoblasts in different stages of differentiation, with a massive disposition involving submucosa, muscularis and serosa. These cells contain intracytoplasmic small optically empty lipid vacuoles that produce indentations of centrally located nuclei; isolated lipoblasts have the appearance of signet ring cells. Predominant cellular population is admixed with scattered mature adipocytes and with stellate/spindled mesenchymal cells. Tumoral stroma has a myxoid character. A distinctive feature of this neoplasm is the existence of a vascular network composed of curved thin-walled capillaries with a branching pattern (“chicken-wire”). The histopathological traits and immunohistochemical profile of this tumor, characterized by positive reaction to Vimentin and S100 and negative staining to pancytokeratin, support the diagnosis of myxoid liposarcoma. The rare incidence of this tumor in the stomach requires a careful microscopical examination, in order to differentiate it from other clinico-pathological entities and to apply an appropriate therapy with a proper monitoring protocol.

“…Histologically, liposarcomas are subdivided into-differentiated, myxoid, round cell and pleomorphic [1] sarcomas. Gastric liposarcomas are very rare and only a few (nine) cases have been reported worldwide [2][3][4] . We report a case of a large epigastric mass proven to be a gastric liposarcoma.…”

Liposarcoma is the most common soft tissue sarcoma and accounts for 15%-20% of all mesenchymal malignancies. The tumor occurs most frequently in the limbs, retroperitoneum and rarely has a visceral location. We report a case of a gastric liposarcoma in a male patient. A 68 years old male patient was admitted to hospital for abdominal discomfort and fullness lasting for a month. He reported rare episodes of vomiting. The CT examination revealed a large epigastric mass (8 cm x 4 cm) involving the lesser curvature of the stomach, in contact with the pancreas and gallbladder. Fatty areas within the mass were evident. A total gastrectomy together with cholecystectomy was performed. The histopathological diagnosis was a well differentiated liposarcoma. The patient did not undergo any adjuvant treatment, he is under close follow up and two years later he is disease free. We report this case due to the rarity of this tumor in the stomach (nine cases reported in the literature).
