EXTRA-ABDOMINAL DESMOID TUMOR OF THE CHEST WALL-A CASE REPORT AND REVIEW OF THE JAPANESE LITERATURE-

Abstract

Extra-abdominal desmoid tumors of the chest wall are rare and only 16 cases have been reported in Japan. We present a case of extra-abdominal desmoid tumor with a review of the literature in Japan. A 30-year-old woman was seen at the hospital because of a tumor in the left chest wall and numness of the left forearm. The tumor was located in the left sternocostoclavicular area. Incisional biopsy of the tumor histologically showed growing lesions of no atypical spindle-shaped fibroblasts with abundant collagen. The tumor including the first and second ribs which was 8.0×6.0×2.5cm in size was resected en bloc. The defect of the chest wall was reconstructed with an artificial dura (Liodura_??_). Histologically, the tumor infiltrated into the muscles and ribs. There has been evidence of recurrence, as of 16 months after the surgery.
