Metastasis of recurrent colonic adenocarcinoma to the mouth

Colorectal adenocarcinoma is a common cancer; however, reports of metastases to the oral region are uncommon. Oral metastases often indicate disseminated disease, the prognosis is poor and management is often palliative. We report the case of a 73-year-old man with recurrent metastatic disease who presented 2 years following his initial surgery for a left-sided colonic adenocarcinoma with a painful oral tumour. Biopsy confirmed adenocarcinoma with similar features to the original colonic tumour; the patient went on to have palliation of his symptoms with radiotherapy.
