Chondrosarcoma of the bone with nodal metastasis: The first case report with review of literature.

ABSTRACT

Primary bone sarcomas are rarely known to metastasize to lymph nodes. This is attributed to paucity of lymphatic channels in the bone. Even though some bone sarcomas like osteosarcoma are known to have nodal metastasis, such affections have not been reported with primary osseous chondrosarcoma. We describe a case of primary chondrosarcoma of proximal humerus with axillary nodal metastasis. The patient underwent a forequarter amputation with axillary nodal clearance. The histopathological examination revealed metastasis of chondrosarcoma in lymph nodes. We also have reviewed the related literature and discussed the possible mechanism of this nodal metastasis.
