DESMOID TUMOR OF THE CHEST WALL WITH CHEST WALL AND BREAST RECONSTRUCTION AFTER WIDE RESECTION-A CASE REPORT-

Abstract

We encountered a case of desmoid tumor of the chest wall. A 38-year-old woman was admitted to our hospital because of a left chest-wall tumor. The tumor was hard and fixed on the left chest wall and 10×12cm in diameter. CT scan and MR Imaging demonstrated the tumor was a solid mass with expansive growth involving the left ribs. Needle biopsy showed growth of collagen fibers without nuclear pleomorphism, suggestive of a desmoid tumor. The tumor was removed together with the left mammary gland and chest wall, however, the nipple and skin of left breast were conservative. Reconstruction of the left breast and chest wall were performed using Marlex mesh and a rectus abdominis musculocutaneous flap. The histological examination confirmed that the tumor was desmoid tumor, but without infiltration of the ribs and pleura. The cosmetic outcome has been excellent with no recurrence 10 months after operation. We reviewed 52 cases of desmoid tumor of the chest wall in Japan. Our review shows that wide resection has a good prognosis compared with simple resection.
