title: Carcinoma of the prostate presenting as a painful parotid mass with mandibular invasion: a case report.
abstract: Prostate cancer metastatic to the parotid gland is exceedingly rare, as only 10 cases have been previously reported in the literature. Symptoms may mimic a parotid infection or suggest a primary parotid tumor. We report a new case of carcinoma of the prostate metastatic to the parotid. The tumor was painful and had invaded the mandible. Fine-needle aspiration of the mass and immunohistochemical staining for prostate-specific antigen confirmed the diagnosis. The patient died 1 month later of an unrelated cause.
