We present the clinical history of a 39-year-old woman, who has survived for over 10 years with metastatic breast cancer. After combined surgery and radiotherapy of the primary tumor and the regional lymph nodes, all bone metastases gradually disappeared under chemotherapy and continuing hormonal treatment. This complete remission included a large mandibular metastasis, which had received additional radiotherapy of 21 Gy. Spontaneous reossification was observed in this location.

Metastasis to jaw bones from renal cell carcinoma as the sole primary source: Systematic review.

Renal cell carcinoma (RCC) has been known for its high propensity of metastasis to unusual locations, and jaw bones (JBs) are one among those sites. The literature has reported several studies analyzing metastatic tumors to the oral region, but very little research work has been published to date to analyze solely JB metastasis (JBM) via RCC. The goal of this study was to examine the published cases of metastasis to JBs from RCC as the sole primary source till date.

Mandibular gingival squamous cell carcinoma (SCC) is the second most common oral cancer after tongue cancer. As these carcinomas often invade the mandible early, accurately defining the resection extent is important. This report highlights the use of preoperative virtual surgery data, computer-aided design and manufacturing (CAD/CAM) technology, surgical guidance, and extended reality (XR) support in achieving highly accurate marginal mandibulectomy without recurrence or metastasis.

Pulmonary metastasis of ameloblastoma is a rare associated with the histopathologically plexiform types of ameloblastoma. In this report, we present an exceptionally rare case of pulmonary metastatic ameloblastoma without local recurrence, emerging 12 years post-initial resection. A female patient, initially diagnosed with mandibular desmoplastic ameloblastoma, revealed masses in both lung fields of the lung on chest radiography, while chest computed tomography revealed more than 10 nodules in both lungs.

Background/aim: Accumulated evidence indicates that interactions among various stromal cells within the tumor microenvironment (TME) significantly influence cancer progression. Oral cancers not diagnosed at early stages are associated with low five-year survival rates, highlighting the need for substantial improvements in patient outcomes. Understanding the interactions between cancer cells and the tumor microenvironment is crucial for identifying methods and developing treatment strategies that more effectively inhibit tumor progression and metastasis.
