A CASE OF A RETROPERITONEAL LIPOSARCOMA WITH COLONIC INVOLVEMENT

Abstract

The patient was a 53-year-old man who underwent laparotomy with a diagnosis of a retroperitoneal liposarcoma on June 12, 1998, followed by laparotomies for local recurrence elsewhere on October 15, 2001 and October 12, 2004. Abdominal CT scan performed on July 5, 2006 revealed a tumor shadow with air-fluid level formation in the lumen. Thus the patient was admitted to the hospital to receive surgery. When he was admitted, the body temperature was 38.5°C, the white blood cell count and CRP were high, 8730 and 8.5, respectively. The patient was diagnosed as having local recurrence of the retroperitoneal liposarcoma and abdominal abscess formation. He was considered to be a possible candidate for operation and was operated on August 8, 2006. The tumor was found to have penetrated the descending colon, so that a partial excision of the descending colon including the tumor was performed. Histopathological study showed that all tumors of the removed materials were well differentiated liposarcoma. The postoperative course was uneventful and he was discharged from the hospital.
We report this case of a retroperitoneal liposarcoma which invaded and penetrated the descending colon, together with some bibliographical comments.
