Nasal papillomas and squamous carcinoma.
There is a known association between carcinoma and nasal papillomatosis when benign nasal papillary lesions have been treated by radiotherapy or by chemotherapy. Invasive carcinoma was found in a patient with nasal papillomatosis that had not been treated previously. Ordinary inflammatory polyps involving the nasal and sinus cavities are extremely common and may mask papillomatosis. Polypoid lesions resected from the nasal ans sinus cavities should always be examined histologically.
