Two Cases of Verrucous Carcinoma of the Larynx / 대한이비인후과학회지

ABSTRACT

Verrucous carcinoma arising from the larynx is a specific clinical entity which is unfamiliar to many otolaryngologists. As judged by reported cases, the mucous membranes of the head and neck are sites of predilection. This lesion makes up approximately 1 to 4% of all laryngeal carcinoma. The biologic behavior of verrucous carcinoma of the larynx is characterized by warty appearance, slow growth, local invasion, scarcity of metastases and benign histology. Most authors prefer surgical treatment for patients with verrucous carcinoma. Radiation therapy appears to hold a higher risk of recurrence, anaplastic transformation of tumor. Recently, the authors have experienced two cases of verucous carcinoma originated from the larynx in old male patients. The two patients were treated by surgical excision.
