Sinonasal inverted papilloma with malignant transformation in the middle ear: a multicentric origin?
Inverted papilloma is a rare, benign tumour representing only 0.5 to 4 per cent of all sinonasal neoplasms; its involvement of the middle ear is extremely rare. We present a case of multicentric inverted papilloma in the sinonasal region and middle ear in a 54-year-old man. The patient later developed neck metastasis secondary to malignant transformation of the inverted papilloma in the middle ear.(Published Online May 4 2006)
