Metastatic carcinomas to the jaw bones are uncommon and comprise to about 1% of all malignant oral neoplasms. The purpose of this report is to present a rare case of metastatic breast carcinoma to bilateral mandibular ramus regions. The present case report is about a 40-year-old female patient with the complaints of a paresthesia in the right mandibular area of the last month duration. She was referred to our department by her oncologist with the differential diagnosis of osteonecrosis or metastasis. She had undergone modified radical mastectomy for invasive lobular carcinoma of the left breast. Oral cavity examination did not reveal the existence of any ulcer or fistula. Panoramic, cone-beam computed tomography (CBCT), and positron-emission tomography (PET) were used for diagnosing the lesions. In panoramic radiography and CBCT images, there were lytic lesions on the both of right and left coronoid, condyle, and ramus of the mandible. PET results showed us fluoro-2-deoxy-D-glucose uptake in the mandible and vertebrae. On the basis of the patient's medical history and paresthesia of the lower lip and chin, the metastatic disease was highly suspected. The patient was referred to her oncologist for further treatment since it was not amenable to the surgical management. The general dentist or dental specialist should maintain a high level of suspicion while evaluating patients with a history of cancer. Paresthesias of the lower lip and the chin should be considered ominous signs of metastatic disease.
