Prostatic adenocarcinoma with mandibular metastatic lesion: case report.

Metastatic lesions of primary tumors, which originate in different parts of the body, comprise almost 1 % of different types of oral cancers. These lesions can affect either bones or soft tissues in the maxillofacial region. Whenever the maxillofacial area is affected, the most common location is in the molar region of the mandible. The clinical presentation of mandibular metastasis follows a clinical pattern characterized by irradiated dental pain in the third molar region. The most frequent sign is parethesia of the area innervated by the mandibular alveolar dental nerve. Differential diagnosis and treatment of these patients can be extremely difficult because there a number of pathologic conditions with similar symptoms and because diagnostic examination can be highly confusing. The aim of this article is to present a case of prostatic adenocarcinoma where the only metastasis was found in the jaw. A literature review will be presented, hoping to contribute to the scarce information regarding this lesion, due to its low frequency and atypical expression of this type of metastasis in terms of etiology, biological behavior and treatment.
