[Untimely extraction in mandibular sarcoma. Apropos of 2 cases]

Two patients with chondrosarcoma and fibrosarcoma of the mandible respectively were seen after abusive extraction of first molars from the tumoral regions. It is essential to recognize presenting signs of mandibular tumors since dental extractions are contraindicated in these cases. These untimely procedures increase the delay between the onset of the first clinical signs, the diagnosis, and the start of therapy, and thus make for a poorer prognosis.
