Sinonasal neurogenic tumours.

Among the surgically excised or biopsied sinonasal tumours in a span of ten years, the neurogenic tumours formed 6.7% of all sinonasal tumours. They were eight in number, three schwannomas, two neurofibromas and three malignant schwannomas with occurrence in a wide age range and no gender predilection. Nasal obstruction and epistaxis were common modes of presentation with a unilateral location. The diagnosis of benign neurogenic tumours do not pose difficulty. However, malignant schwannoma should be considered when one encounters a cellular spindle cell lesion in sinonasal region.
