Primary Peritoneal Liposarcoma in a Middle Age Woman

Liposarcoma is a mesenchymal malignant tumor and is the second-most common soft tissue sarcoma in adults. Primary peritoneal liposarcoma is very rare. We report a case of abdominal liposarcoma originating from peritoneum in 57-year old woman, presenting with hugeness of abdomen. The symptoms had been begun from one month ago without any pain, discomfort or gastrointestinal symptoms. In physical examination a large mass with approximate size of 30×35 cm and firm density was found in left lower part of abdomen. The patient underwent laparotomy. The pathologic diagnosis was well differentiated liposarcoma. After 5 months of treatment the patient is well and no problem, complication or recurrence has been reported.
