Panoramic showed several irregular osteolytic lesions of the mandibular body. CT-scan images showed a large irregular hypodense lesion and a tissue infiltration of the left mandibular body blowing the buccal cortex. Histopathology showed a neoplastic proliferation of carcinomatous cells positive for the cytokeratin AE1\/AE3. A diagnosis of breast carcinoma mandibular metastasis was made. The patient was referred sent to the oncology committee. She was treated with Palbociclib and hormone therapy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical discussion:<\/jats:title>\n                    <jats:p>In the oral cavity, the mandible is the most common site for metastasis.
