Increasing dyspnea due to an anterior mediastinal mass

Huge sternal chondrosarcoma: a case report

A 75-year-old man presented very late with a huge sternal mass that measured 91 × 84 mm on computed tomography. A core needle biopsy revealed atypical cartilage tissue, suggesting chondrosarcoma. The mass was resected and the defect was reconstructed with bone cement, Prolene mesh, and a muscle flap.

A chondrosarcoma in the anterior mediastinum mimicking a thymoma

A chondrosarcoma in the anterior mediastinum is a rare finding with a relatively good prognosis. We describe a case of a 75-year-old man with a 2-year history of neck discomfort and weight loss. Imaging showed a homogenous tumor with a minor compression on the anterior part of the heart. It had close relation to the ribs, no surrounding fat, and a thymoma was suspected. Biopsy prior to surgery was impossible due to the location of the tumor. Unfortunately, final pathology from the surgical specimen revealed a chondrosarcoma.

A rare case of primary chondrosarcoma arising from the sternum: A case report

The current study reports a case of an extremely rare tumor that presented in an uncommon location, which was successfully treated via radical resection and reconstruction. A 37-year-old female, with no notable medical history, with the exception of a cesarean delivery, was admitted to The First Affiliated Hospital of Wenzhou Medical University (Wenzhou, China) due to pain and a lump of the anterior chest wall. The mass was identified on the manubrium sterni and was not tender on palpation. A chest computed tomography (CT) scan reconstruction identified the abnormal mass on the manubrium sterni (size, 5×4 cm in diameter) and positron emission tomography-CT interpretation strongly indicated a type of well-differentiated malignant tumor, such as a giant cell tumor. An aspiration needle biopsy was not conducted, however, the patient underwent tumor radical resection and sternal reconstruction using steel wire and titanium mesh. Histopathological examination of the surgical specimen determined the diagnosis of chondrosarcoma. A postoperative chest X-ray revealed that the sternal defect had repaired well, therefore, this procedure may be highly beneficial in future for repairing defects in the sternum.
