Recurrent respiratory papillomatosis with lung involvement.

The case of a 27-year-old male with recurrent respiratory papillomatosis including lung involvement is presented. Laryngotracheal papillomatosis with lung involvement is a rare entity associated with human papillomavirus infection. Computed tomography (CT) was essential in guiding diagnostic and therapeutic approaches. Knowledge about the findings of this disease is needed for correct diagnosis, since findings are nonspecific. Lesions may show malignant transformation; regular follow-up with CT is essential.
