Abstract

Background. Metastatic adenocarcinoma of the colon is a frequently encountered medical situation. Metastasis to the mandible from adenocarcinoma of the colon is very unusual and rarely reported. We report the case of a 73-year-old man with metastatic adenocarcinoma to the mandible. Methods. The patient was referred for evaluation of a mass of 2 months' duration in the right parotid gland. He gave a history of watery bowel movements of unknown duration. Physical examination revealed a 7- × 6-cm hard mass, which seemed to be fixed to the right mandible. A CT scan revealed a destructive process involving the ramus and condyle of the right mandible that invaded the pterygopalatine fossa, pterygoid muscles, and middle cranial fossa. CT scans of the abdomen and pelvis revealed a 5-cm mass in the sigmoid colon with metastases to the liver. Results. A biopsy of the mass in the mandible was performed, and metastatic adenocarcinoma of colonic origin was diagnosed. Colonoscopy and biopsy of the colonic mass substantiated that the sigmoid colon was the primary site of the cancer. Because the patient had disseminated disease, he declined treatment, and he died shortly thereafter. Conclusions. Although rare, metastatic adenocarcinoma from the colon to the mandible and parotid area should be included in the differential diagnosis of masses in this area. After analysis of our case and a review of the literature, we conclude that metastasis from adenocarcinoma of the colon is quite rare and represents incurable disseminated disease.
