Metastatic adenocarcinoma of the temporomandibular joint from the cardia of the stomach: a case report.

A case is presented of a 67-year-old man with adenocarcinoma of the gastric cardia that metastasised to the temporomandibular joint (TMJ). A carcinoma of the cardia metastatic to the TMJ has not previously been reported. The case is unusual in many respects. The condyle and disc were anteriorly displaced by the tumour, resulting in progressive mandibular deviation and crossbite. Radiographically, however, no destructive changes of the joint were observable. Tumour staging showed this lesion to be the only distant metastasis.
