We present a patient with intestinal type adenocarcinoma of the nasal cavity. A 63-year-old male was referred to our hospital due to repetitive, right-side nasal bleeding over a period of a year. Nasal endoscopy revealed a right-sided olfactory cleft tumor. CT and MRI studies detected a right nasal tumor 37mm in the longer axis and 26mm in the shorter axis. The tumor was diagnosed as a Stage Ⅳa nasal carcinoma due to extension to the sphenoid sinus. Transnasal endoscopy-assisted skull base surgery was performed. No postoperative complications except anosmia were observed. Histological findings confirmed an intestinal type adenocarcinoma without infiltration of dura and negative margins. Two years after 56Gy of postoperative radiotherapy, neither locoregional recurrence nor distant metastasis was found.
