Colorectal cancers have potential for lymphatic and hematogenous metastases. Surgery is the definitive treatment, but the prognosis can be improved with the addition of chemotherapy, radiotherapy or both. However, the incidence of recurrence, both local and distant, remains significant. Distant metastases occur most often in the liver and lung; however, metastases to bone, adrenals, lymph nodes, brain, skin and the oral region have been reported. Metastases to the oral region are uncommon and may occur in the oral soft tissues or jaw bones. The prognosis in such patients is usually very poor. We report a case of colorectal carcinoma with metastasis to the floor of the mouth. This is probably the first reported case of metastasis to the floor of the mouth in a patient with colorectal cancer.
结直肠癌有发生淋巴转移和血行转移的可能。手术是确定性治疗方法，但化疗、放疗或两者联合应用可改善预后。然而，局部和远处复发的发生率仍然很高。远处转移最常发生在肝脏和肺；不过，也有转移至骨、肾上腺、淋巴结、脑、皮肤及口腔区域的报道。转移至口腔区域并不常见，可能发生于口腔软组织或颌骨。这类患者的预后通常很差。我们报告1例结直肠癌转移至口底的病例。这可能是结直肠癌患者转移至口底的首例报道病例。
