title: Primary intraosseous carcinoma involving the anterior mandible.
abstract: A case is reported of a primary intraosseous carcinoma arising in the anterior mandible with metastasis to the submandibular lymph node in a 69 year-old Caucasian female. The patient initially presented with a burning sensation in the oral cavity in 1983, when no obvious pathological finding was noted; she returned 2 years later with a firm buccal swelling which had increased in size after the extraction of a mobile tooth. The tumour proved to be a primary intraosseous intraosseous carcinoma; extensive investigation did not reveal a primary carcinoma elsewhere.
