Summary
Metastases to the mandible from large bowel tumors are rare, with only 20 cases reported. This case highlights the importance of considering colorectal cancer in mandibular lesions for patients with a history of malignancy.
Area of Science:
- Oncology
- Oral Medicine
Background:
- Metastases to the mandible are rare, comprising 1% of oral tumors.
- Breast cancer is the most common primary source of mandibular metastases.
- Large bowel tumors rarely metastasize to the mandible, with only 20 prior reports.
Observation:
- A 59-year-old woman presented with metastatic disease to the mandible.
- The primary tumor was identified as an adenocarcinoma of the sigmoid colon.
Findings:
- This case represents a rare instance of sigmoid colon adenocarcinoma metastasizing to the mandible.
- The incidence of large bowel tumors metastasizing to the mandible is exceptionally low.
Implications:
- Mandibular metastases from colorectal cancer, though rare, should be considered in the differential diagnosis.
- Oral and mandibular lesions in patients with a history of malignancy warrant thorough investigation for metastatic disease.
