Abstract
A case of abdominal desmoid tumor in a relatively aged woman was experienced. A 60-year-old woman was seen at the hospital because of a tumor in the right lower abdomen. It was a hard and unmovable tumor measuring 9×9 cm. Abdominal ultrasonogram disclosed a mass lesion showing heterogenous echogenicity without a clear border. Abdominal CT revealed a tumor of which density was higher than that of the soft tissue with strong enhancement by a contrast medium. Laparotomy was performed under general anesthesica, and a very hard tumor was found in the right rectal muscle adhering to the major omentum and transverse colon. The patient underwent wide local resection of the tumor with 1 cm surgical margin. The defect of the abdominal wall was repaired with Marlex mesh (polypropylene). Histologically, fibrous tissue interlaced with the surrounding muscle and adipose tissues without cytologic atypism were observed. A diagnosis of the abdominal desmoid tumor was made. No tumor has recurred for one year and eight months after the operation.
