Abstract
A 47-year-old female patient with recurrent juvenile-onset laryngotracheal papillomatosis for 27 years had multiple bilateral pulmonary lesions, the largest of which was a well-differentiated squamous cell carcinoma. This case is unique because the malignant transformation occurred in a nonirradiated, nonsmoking patient.
