mesenchymal chondrosarcoma of the mandible: a case report

Mesenchymal chondrosarcoma as an aggressive type of chondrosarcoma shows a characteristic biphasic histopathologic pattern. the head and neck region is included a high proportion of extra skeletal sites. very rare examples of mesenchymal chondrosarcoma involving the mandible have been described. based on fragmented or tiny specimens, the diagnosis of this lesion has been remained a challenge because the specimens may contain only one of the two neoplastic elements. we report a rare case of mesenchymal chondrosarcoma of the mandible in a 19 years old male with delaying in diagnosis due to massive extension of the tumor to the soft tissues.
