[Pulsating tumor of the sternum: enlarged exeresis and reconstruction with marlex-methylmethacrylate prosthesis].

The authors report on a rare case of pulsating tumor of the sternum. En bloc resection was carried out with removal of the sternal manubrium and body, tracts of the I-II-III rib with the intercostal muscles and part of the left pectoralis major. Reconstruction of the thoracic wall was performed with a marlex MMA sandwich prosthesis. From a histological viewpoint, the carcinoma was well differentiated and compatible with thyroid primitivity. Non complementary antiblastic therapies were provided as all the examinations carried out were negative and the intervention was radical. The patient had been followed-up with serial controls and three complete stagings at one, three and five years after intervention (CT, echography and function tests of the thyroid, bone scintigraphy). At follow-up of more than six years the patient is doing well and is event free. The authors believe, even with the help of reports from the literature that, in sternal metastases from thyroid carcinomas, especially when single and large, surgical therapy is required.
