A case report of condyle metastasis and a review of the literature.

Metastasis of the oral cavity is a rare condition and should be investigated for a primary tumor in the lungs, breast, kidney and prostate. Involvement of the mandibular condyle frequently mimics TMJ dysfunction with pain, swelling and limitation of mouth opening. We report the case of atypic TMJ dislocation as an inaugural sign of condyle metastasis. We also discuss the diagnostic approach by a brief review of the literature.
