Numb chin syndrome: a metastatic deposit in the mandible.

UNLABELLED: Metastatic deposits in the mandible are discussed and a case of leiomyosarcoma arising from a testicular primary is presented. The patient presented with symptoms typical of those that would present to a general dental practitioner. The various stages involved in the diagnosis and management of the condition are discussed.

CLINICAL RELEVANCE: Intra-oral malignant secondary tumours may present to dentists with signs and symptoms similar to those of benign, cystic or infectious processes. Metastatic tumours in the oral cavity are uncommon, most commonly arising in the mandible. Owing to their relative infrequency, these tumours present a challenge in diagnosis and treatment.
