Rare case of chondrosarcoma of the manubrium sterni: Management challenges and insights (a surgical case report)

Chondrosarcoma of the manubrium sterni is an exceedingly rare localization of chondrosarcoma. Its treatment poses a significant therapeutic challenge due to the tumor's proximity to the mediastinal organs and the clavicles. This challenge is magnified when the inner ends need to be resected due to tumor contact with the sternoclavicular joints and, more critically, during the reconstruction of the thoracic wall.

We present the case of a 71-year-old female with a 45x42x51 mm chondrosarcoma of the manubrium sterni, extending to both sternoclavicular joints. The diagnosis was confirmed cytologically and histologically after an ultrasound-guided biopsy. A surgical strategy involving en bloc resection of the manubrium sterni, the internal ends of both clavicles, and the first two ribs, followed by sternal reconstruction using a synthetic manubrial plate and titanium costal staples without clavicular bridging, was indicated and executed.

This case outlines the surgical considerations and techniques adopted for this complex procedure, emphasizing the operative planning and interdisciplinary collaboration required for a successful outcome.

At 18 months post-surgery, the patient demonstrated favorable clinical and radiological progress, indicating a positive response to the treatment strategy employed.
