Description: Papillomatous lesion in neck of long standing.

History: This congenital nevus(papillomatous type) was stable since birth. Dermatoscopic description: globular pattern. Congenital nevi generally appear as flat or elevated light-brown to dark-brown lesions. The surface can be smooth, papillomatous or verrucous. Numerous hairs are often present within a lesion-the nevus then being commonly called hairy nevus. A particular clinical dilemma is the congenital pseudomelanoma, a type of congenital nevus characterized by several to numerous, round to oval, dark-brown or black pigmented areas within an otherwise stereotypical congenital nevus clinically simulating a melanoma within a pre-existing congenital nevus. Attempts have been made to classify congenital nevi according to their size in adulthood, e.g., less than 1.5 cm for small congenital nevi, more than 1.5 cm to 20 cm for intermediate congenital nevi, and 20 cm (more than 7 cm in newborns) or more for large congenital nevi.
