Clinicopathological and histological behavior of mesenchymal chondrosarcoma involving maxilla.

Mesenchymal chondrosarcoma (MC) is a rare variety of chondrosarcoma (CS), which is both clinically unique and histologically distinct compared with conventional CS. Maxillofacial MCs are aggressive, have a tendency for recurrence and significant distant metastasis to lung and bone, and are associated with overall poor prognosis. Histopathologically, it is a biphasic tumor comprising of islands of hyaline cartilage with undifferentiated small round cells. Here, we present an interesting case of MC involving the left half of maxilla along with a brief review of the relevant literature.
