Metastases from colorectal cancer can occur either through the lymphatic or by hematogenous spread. The most common metastatic sites are the lung and liver. Nasopharyngeal metastasis from colorectal cancer has never been previously reported in the literature on the internet databases we can found. In this paper, we present the case of a 79-year-old male suffering from adenocarcinoma of the rectum with distant metastases to the liver, lung, and nasopharynx. Over the previous 7 years, he had received treatment for rectal cancer including radical surgery (miles surgery), chemotherapy, hepatectomy, and pneumonectomy. After local nasopharyngeal radiotherapy, the patient's quality of life significantly declined and they eventually died of dyspnea caused by airway obstruction due to a nasopharyngeal mass after 7 months of palliative treatment involving pain relief from end-stage disease. Nasopharyngeal metastases from colorectal cancer are extremely rare in the clinic. To the best of our knowledge, this is the first case reporting this occurrence which not only extends the disease database but also warns doctors to pay more attention to these clinical scenarios. Strict monitoring of patients with colorectal cancer after primary treatment could lead to the early diagnosis of metastases and give patients better opportunities for treatment and improved prognosis.
