The histopathology report was schwannoma of the nasal cavity. The section showed polypoidal strips of inflamed nasal mucosa and large portions of benign nerve sheath tumour characterised by Antoni A and Antoni B areas. Nuclear palisading is noted with engorged vessels within the tumour. Follow up after two months showed no recurrence in the nose or any other complaints. Benign schwannomas are the commonest type with less than 40 cases occurring within the paranasal sinus.
Lesions involving the paranasal sinus often lead to pain in the facial or orbital area.
Schwannomas can show local bony destruction with possible intracranial extension, including visual disturbances. Neurinomas involving the nose, throat or larynx are usually solitary lesions and on examination they present as localized masses in the nasal cavity. Radiology is invaluable for preoperative planning of excision. In addition, biopsy can confirm the diagnosis. However, brisk bleeding may occur at biopsy or removal due to the rich vascular stroma.
