    Abstract:
    This report describes a rare case of intra-abdominal liposarcoma in a 67-year-old woman. The patient presented at Internal Medicine Unit in May 2004, to study of thyroid pathology. The clinical examination was normal, except for the finding of an asymptomatic mass in the abdomen. The patient knew the existence of tumor since time ago, but she confesses to have only occasional discomfort. In the abdominal ultrasonography a solid mass with large cystic component was detected but relation with other organs was not clear. Computed tomography revealed the presence of a mass with solid and cystic components, in contact with small intestine in the left side of abdomen. A complete resection of tumor arising from mesentery of jejunum was performed successfully with end to end anastomosis. The gross specimen was lobulated and measured 8.5 x 7.5 cm. The histopathology analysis showed proliferating lipoblasts with irregular nuclei on a myxoid background, with plexiform vascular pattern, characteristics belongs to myxoid type liposarcoma. The patient is alive and well one year after removal of tumor. The uncommon site and the exceptional cystic morphology of tumor are discussed, and so it must be included the primary mesenteric liposarcoma in the differential diagnosis of intra-abdominal tumors with cystic large areas.
