Background:
Most of the sinonasal tumours are of epithelial origin. Leiomyomas are very uncommon in the upper respiratory tract and extremely rare in the nasal cavity and paranasal sinuses. They account for less than 2.5% of the mesenchymal neoplasms of the sinonasal tract and the nasopharynx.
Aim:
Report of a new case which will be added to the 30 cases of primary sinonasal leiomyogenic tumours reported in the litterature. The clinical and pathological characteristics of this tumour will be discussed.
Case Report:
We report a case of 48-year-old woman complaining of nasal obstruction corresponding to a polypoid lesion of the sinonasal cavity. The histological examination of the removed mass concluded to a leiomyoma.
Conclusion:
Leiomyoma in this location has no specific physical or radiological findings. Only the histological examination can definitively made the correct diagnosis.
