[Temporomandibular joint dysfunction as a result of a condylar metastasis].

An 83-year-old man reported recent temporomandibular joint complaints and a swelling near his ear. The swelling moved whileopening the mouth. Additional imaging showed an osseous deviation of the right condyle with extension into the masticator space. In addition, several lytic and expansive bone lesions were visible in the skeleton, which initially suggested multiple myeloma. However, blood tests pointed in the direction of prostate cancer that had been treated twenty years earlier. There appeared to be extensive osseous metastatic recurrent prostate carcinoma with a metastasis in the right condyle of the mandible. The patient was treated with palliative systemic therapy.
