In this report, we describe a case of Inflammatory linear verrucous epidermal nevus (ILVEN) that clinically and histologically mimicked Blaschkoid (linear) lichen planus, linear psoriasis, and other linear dermatoses, for could be diagnosed by histopathologic findings. ILVEN is typically refractory to treatment, but accordingly the data of literature the various methods of cure were tried from treatment with the administration of calcipotriol, topical application of momethasone furoate 0.1%, combination therapy with topical tretinoin, 5-fluorouracil creams, crisaborole 2% ointment to invasive methods such as carbon dioxide gas laser, pulsed dye laser, UV 308-nm excimer laser. Consequently, the differential diagnosis between ILVEN and similar disorders are necessary to avoid applying an inadequate therapy.
