Oral metastatic tumors are rare and usually indicate late stage of the disease. A 50-year-old female patient with previous medical history of treatment for colon adenocarcinoma 2 years earlier was referred for evaluation of an asymptomatic lesion with 1 month of evolution. Additionally, the patient was under investigation of bone metastasis. Extraoral examination did not detect lymph nodes. Intraoral examination revealed a pedunculated reddish-purple nodule measuring around 3.0 × 2.0 cm in the gingiva of the posterior left maxilla with bleeding to palpation. Cone beam computed tomography showed bone loss surrounding the molar region. An excisional biopsy was performed, and according to the microscopic and immunohistochemistry findings, the final diagnosis of colon adenocarcinoma metastasis was established. Metastasis in L2 vertebra also was confirmed. A palliative radiotherapy/chemotherapy was established; however, the patient died 1 month after the diagnosis. Metastatic tumors should be considered as differential diagnosis of oral lesions in patients with history of malignant neoplasms.
