ABSTRACT

Verrucous carcinoma (VC) is a well-differentiated, slow-growing, rare variant of squamous cell carcinoma that tends to locally invade and recur, and rarely metastasizes. It is found in three major locations: the oral cavity, the anogenital region and the acral surfaces. It occurs predominantly in males after the fourth decade of life. VC clinically appears as an exophytic gray-white or red mass with a very broad base of attachment and a surface characterized by epithelial projections and keratin-filled invaginations. First-line treatment is wide surgical excision that sometimes is extremely destructive.

To date, typical dermoscopic aspects of VC have not yet been described. Dermoscopy is important to exclude other malignant tumors, in particular, acral melanoma.

Dermoscopic findings that we can observe in VC are keratin structures and keratin masses; red dotted, looped and coiled vessels in papillary whitish structures; black dots; and ulceration.
