Verrucous carcinoma of the larynx.

Verrucous carcinoma of the larynx is an uncommon but distinct variety of well differentiated squamous carcinoma and accounts for 1-2% of all laryngeal squamous carcinomata. Awareness of the condition both by clinician and histopathologist is essential otherwise the diagnosis may not be made. From a review of the literature and personal assessment of the cases presented here it would appear that local conservative endoscopic treatment with careful follow-up may be the treatment of choice for certain verrucous carcinomata. Such treatment may be either suction diathermy or cryosurgery or laser surgery. Anaplastic transformation has been said to occur following irradiation of these tumours, though this view is not held by all clinicians, some of whom recommend radiotherapy for selected cases.
