OBJECTIVE This article describes the case report of a prostate adenocarcinoma in the mandible. BACKGROUND Prostate adenocarcinoma is a malignant tumor common in men from the fourth decade of life. The occurrence of oral metastatic lesions is rare. CASE REPORT A 78-year-old male patient was referred to the oral and maxillofacial surgery service of the Pontifical Catholic University of Rio Grande do Sul for complaints of painless volume increase in the mandible. The diagnosis through the association of clinical, radiographic, and histopathological examination with the patient's health history determined that the lesion was prostatic adenocarcinoma metastasis. CONCLUSION Despite the rare occurrence of metastases in the oral region, the dental surgeon should be aware of the possibility for correct diagnostic conduction and, subsequently, the institution of treatment in the early stages of disease.
