A 61-year-old man ameloblastoma involving the maxillary antrum and the nasal cavity was seen on January 25, 2002, for 24-month history of slowly increasing left nasal obstruction. He reported severe left nasal obstruction, but had no nasal discharge, postnasal drip, cheek swelling, or dental or vision problems. Radiography showed a multilobular legion in the left nasal cavity and the left maxillaly antrum with extension to the molar area, which was most remarkable with T2-weighed MM. On May 8, we explored the left maxillary sinus via a Caldwell-Luc approach. The tumor occupied the maxillary antrum and extended into the left nasal cavity via the maxillary ostium. The lateral maxillary wall was eroded, but the tumor was not invasive and was removed totally with minimal bleeding. Histologically, the excised tumor was compatible with ameloblastoma, plexiform variant.

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.
