Photoclinic Diagnosis: Metastatic Prostate Adenocarcinoma to the Mandible

A 59-year-old man was referred to the department of Oral and Maxillofacial Pathology of Tehran University of Medical Sciences because of a painless swelling in the left mandibular premolar and molar area. The swelling was a hard non-tender _xed mass of approximately 3.5×3 cm, which was present for two months. The enlargement caused obvious expansion and asymmetry of the face. Occlusal radiography showed some evidence of expansion in the buccal cortex but it was nondiagnostic (Figure 1). Therefore, the patient had a computerized tomography (CT) scan, which revealed increasing opacity and irregular periosteal reaction in buccal side. The patient’s bone scan revealed several foci of increased radiotracer uptake in different bones.
