Malignant Transformation of Nonirradiated Recurrent JuvenileLaryngeal Papillomatosis

Abstract

Very few cases of spontaneous malignant transformation of nonirradiated recurrent juvenile laryngeal papillomatosis (JLP) have beenreported in literature. We document a case of invasive laryngeal carcinoma arising in pre-existing juvenile laryngeal papillomatosis. Aftermultiple CO2 Laser resections, a 29-year-old female, non-smoker, who had never received radiation therapy, developed a florid exophytictransglottic squamous cell carcinoma. Therefore, regular extensive biopsies and careful histopathological examination are required in casesof JLP. We also emphasize the need to maintain a high index of suspicion for malignant transformation in long standing cases.
