Abstract
Malignant transformation of respiratory papillomata is not uncommon in the presence of precipitating factors such as tobacco smoking and therapeutic irradiation. Respiratory papilloma changing to carcinoma in the absence of smoking and irradiation is seldom seen, with only about 20 documented cases presented in the literature. Here we report one such case in a 30-year-old male patient.
