Epidermal nevus is a skin lesion characterized by a wart‑like papule. The lesions may be slightly warty (psoriaform) or scaly (eczema‑like). Treatment options include dermabrasion, cryotherapy, laser therapy, and surgical excision.
○ Diagnosis and Treatment It is important to distinguish epidermal nevus from warts, which can appear similar. Epidermal nevus can be removed by laser ablation.
Inflammatory Linear Verrucous Epidermal Nevus is a rare disease of the skin that presents as multiple, discrete, red papules that tend to coalesce into linear plaques that follow the Lines of Blaschko. The plaques can be slightly warty (psoriaform) or scaly (eczema-like). ILVEN is caused by somatic mutations that result in genetic mosaicism. There is no cure, but different medical treatments can alleviate the symptoms.

Typical Case

The patient first showed up at five months old with yellow patches on the right front of the scalp. By six months, they had hyperpigmented verrucous papules on the back right side of the scalp. Over the past five years, these spots slowly grew bigger but stayed only on the right side of the face, scalp, and neck. They aren't painful or itchy, and the patient is growing normally. The right cheek and forehead have slightly raised, yellow patches that stretch onto the front and side of the scalp. Connected to these patches are hyperpigmented, verrucous papules, forming lines from the back of the scalp to the back of the neck on the right side.
