Abstract
Primary Chest Wall Chondrosarcoma Presenting as a Breast Mass
Highlights
Chondrosarcoma is a malignant neoplasm that produces a chondroid matrix with primary chondrosarcomas arising de novo and secondary chondrosarcomas developing in pre-existing benign lesions [1,2]
We present the case of a 46-year-old female presenting with an enlarging painless palpable mass of the right breast that was diagnosed as a chondrosarcoma after workup
The incidence of a conventional primary chondrosarcoma is less than 0.5 cases per million people per year
Summary
Chondrosarcoma is a malignant neoplasm that produces a chondroid matrix with primary chondrosarcomas arising de novo and secondary chondrosarcomas developing in pre-existing benign lesions [1,2]. While most primary chest wall chondrosarcomas are thought to arise de novo, as many as 10% are contributed to radiation exposure from treatment of previous malignancies, including breast cancer and lymphoma [6,7]. We present the case of a 46-year-old female presenting with an enlarging painless palpable mass of the right breast that was diagnosed as a chondrosarcoma after workup. CT was obtained to define the extent of the tumor for preoperative planning and revealed a multilobulated septate 15 x 14.5 x 10 cm mass with several central scattered punctate mineralization’s arising from the anterolateral segment of the right fifth rib (Figure 5). MRI showed a large lobular T2 hyperintense mass arising from the anterior aspect of the right fifth rib invading the overlying pectoralis major muscle. 46-year-old female with conventional primary chondrosarcoma of the right fifth rib.
