Backgrounds: Mucoepidermoid tumours arise from the ductal cells of the salivary glands, most commonly the parotid. The occurrence of these tumours in the mucus glands of the air passages is extremely rare. They are very aggressive tumours with poor prognosis.
Case: A case of nasal mucoepidermoid carcinoma with probable origin from the middle turbinate is reported.
Conclusion: Nasal mucoepidermoid carcinomas are extremely rare. They usually present with symptoms similar to sinusitis. When dealing with a recurrent/aggressive tumour in the ethmoids, the possibility of mucoepidermoid carcinoma can be considered in the differential diagnosis. They are aggressive tumours with a poor prognosis.
