Manubrioclavicular and Manubriosternal Reconstruction After Radical Resection for Chondrosarcoma of Manubriosternum: A Modified Surgical Technique.

Abstract

Primary chondrosarcoma of the manubriosternum is a rare tumor. We describe the case of a 42 year-old man who presented with a swelling of the anterior chest wall. The computed tomography scan of the thorax showed a manubriosternal mass involving both clavicles. True-cut biopsy revealed a low-grade chondrosarcoma. The manubrium, the medial part of the clavicles, the sternum, and all costal cartilages were excised en bloc with wide, clear margins and reconstructed successfully without any residual deficit regarding the stability of the chest wall and upper arm movements. We present this rare case with a modified reconstruction technique using a methyl methacrylate Marlex mesh sandwich plate with excellent results. After 2 years' follow-up, there was no radiologic or clinical signs of recurrence.
