title: Mesenchymal chondrosarcoma of the right buccal region: A case report and review of the literature.
abstract: Extraskeletal mesenchymal chondrosarcoma (EMCS) is a rare malignant cartilaginous tumor arising from the soft tissues. The most common areas of extraskeletal origin are the lower extremities, the orbits and the central nervous system, among others. In this study, the case of primary EMCS arising from the right buccal region in a 26-year old female is presented. Histological and immunohistochemical analysis confirmed the diagnosis of EMCS. Subseqently, the patient was treated with radical surgery, but declined chemotherapy or radiotherapy, which was recommended. One year after surgery, no recurrence had been identified in the patient. To the best of our knowledge, only one case of primary EMCS of the buccal region has been reported previously. In the current study, a case of primary EMCS of the buccal region is presented.
