Pulmonary Squamous Papilloma Complicating Recurrent Tracheal Papillomatosis

Recurrent respiratory papillomatosis is caused by the Human Papilloma Virus and occurs primarily in children and adolescence. Most commonly, disease remains localized to the larynx and spontaneously regresses, but in rare cases there may be pulmonary involvement. We present a case of a 17 year old female with recurrent respiratory papillomatosis who develops pulmonary involvement in the form of squamous papilloma. We present the clinical findings; discuss the potential for malignant transformation and the need for screening and prevention.
