Massive Vulvar Linear Verrucous Epidermal Nevus Presenting at Menarche

Epidermal nevi are benign hamartomatous growths of the skin that present at birth and develop in early childhood often linearly along the "lines of Blaschko." Verrucous linear epidermal nevi are the most common epidermal nevi and often are located on the trunk or extremities. There is minimal evidence regarding vulvar involvement and subsequent management of the associated cosmetic deformity in this anatomic location.

An 11-year-old menarchal girl who underwent full-thickness dermal excision of a 9.6 × 4.5 × 3.2 cm left benign vulvar epidermal nevus (noninflammatory type) with primary reconstruction and closure using a mons rotational skin flap.

Surgical excision of large vulvar nevi can be achieved with desirable cosmetic outcomes with use of rotational skin flaps and primary closure.
