ABSTRACT

Liposarcoma is a malignant neoplasia of mesodermal origin that affects 10 to14 % of all soft tissue sarcomas. It accounts for less than 1 % of all the malignant tumors. This is a patient who went to the physician's office because of weight loss and feeling of gastric plenitude. Fifteen centimeter long tumor of firm consistency, smooth surface and regular contours, which made the left hemiabdomen inflamed, was palpated. Ultrasound test of the abdomen, simple and contrasted computerized tomography of the abdominal region were performed and finally the tumor mass was detected. Additionally, supra and infraumbilical medial abdominal exploratory laparotomy was performed, with total excision of the tumor mass and of the left kidney that seemed to be affected by the tumor. The hispatological study of the sample reported the existence of myxoid liposarcoma. Six months after these procedures, the patient remained asymptomatic, gaining weight and free of tumor relapse according to the clinic and the progressive studies. Retroperitoneal myxoid liposarcoma is a rare tumor that has no characteristic symptoms. Computerized tomography is the fundamental study for the imaging-based diagnosis. The treatment of choice is total excision of tumor, with oncologic safety.
