Leiomyoma of the nasal cavity. A case report

Most of the sinonasal tumours are of epithelial origin. Smooth muscle tumours are extremely rare, they account for less than 2.5% of the mesenchymal neoplasms of the sinonasal tract and the nasopharynx. Fewer than 30 cases of primary leiomyogenic tumours have been reported in the sinonasal tract with almost an equal frequency of benign and malignant types. We report a case of a rare leiomyoma of the nasal cavity. The pathological and the clinical characteristics of this tumour are discussed.
