Abstract
The most common sites of metastasis from colorectal cancer are liver, lungs, and peritoneum. Oral cavity metastasis is extremely rare, accounting for only 1–2% of all oral cancers. We report the case of a 71-year-old male who presented with hard palate metastasis 20 months after his initial diagnosis for T4N1M1 rectal adenocarcinoma according to the UICC TNM classification. To the best of our knowledge, hard palate metastasis from colorectal cancer has never been previously reported in the literature. The hard palate metastasis deteriorates oral function, resulted in unfavorable prognosis. Early detection of oral cavity metastasis could lead to the opportunities for additional treatment and improve outcomes following treatment.
