Mucinous intestinal-type adenocarcinoma is a rare malignant tumor of the nasal cavity and paranasal sinus. We describe a case of mucinous intestinal-type adenocarcinoma of the ethmoid sinus in a 69-years old man. He had no history of wood dust inhalation. CT and MRI demonstrated a large mass that extended from the ethmoid sinus to the anterior skull base. We perfomed anterior craniofacial resection of the tumor, and postoperative radiotherapy (60 Gy). Histopathologic examination showed that the tumor contained atypical intestinal mucosa, papillary growth, well formed glands distended with mucus. The prognosis was very poor. Local recurrence, and metastases to the lung and brain were found 7 months after the surgery. The patient died at 4 months postoperation.
Key words :mucinous intestinal-type adenocarcinoma, ethmoid sinus, nasal cavity, craniofacial resection
