Colorectal carcinomas most often metastasize to the liver and lung, whether by hematogenous or lymphatic spread. Metastasis to other sites has been reported in the literature but is extremely rare. We are reporting a case of a 65 year old male who was being treated at King Hussein Medical Center as a case of primary nasopharyngeal carcinoma for five years, only to be later discovered that he actually suffers from a primary sigmoid tumor with distant nasopharyngeal metastasis. Metastatic nasopharyngeal tumor of colonic origin is very infrequent and is even indistinguishable from a primary tumor by routine pathological studies (1).
