Abstract

Verrucous epidermal nevus represents the most frequent variant of epidermal nevus, a general term encompassing a variety of hamartomatous ectodermal lesions characterized by epidermal changes. Clinically, it presents as skin-colored, gray-brown verrucous papules, often coalescing to form well-demarcated papillomatous plaques. Dermatoscopy frequently shows brown circles, which consist of oval or round structures characterized by a hyperchromic brown edge surrounding a hypochromic area. Other findings include fissures, keratin-filled crypts, comedo-like openings, milia, brownish globules, and cerebriform or cobblestone appearance.
