An unusual case of laryngeal carcinoma metastasizing to the small intestine.

An unusual case of laryngeal carcinoma metastasizing to the small intestine is reported. The patient was admitted to our hospital due to hoarseness, sore throat and dyspnoea. Pathological examination on the laryngeal mass revealed it to be moderately differentiated squamous cell carcinoma, staged as T4N0M0. A total laryngectomy and right modified neck dissection were performed. Over two years after the operation a small intestinal tumour was found, with a resultant resection of the ileum and sigmoid colon. An infiltration of the cell nests of squamous cell carcinoma were present at the submucosal regions of the ileum. These findings indicated that the laryngeal cancer had already metastasized to the small intestine at the time of the initial treatment.
