Inflammatory linear verrucous epidermal nevus (ILVEN) is a rare type of epidermal nevus, commonly arising in childhood. We present a case of a 13‐year‐old female with Blaschkoid psoriasiform plaques extending from her left foot to the scalp, sparing the right side of the body. While treatment options historically show variable success, we trialed an IL‐17a receptor inhibitor as studies have shown increased levels of IL‐17 receptor expression in ILVEN keratinocytes. At both 3 and 6 months after treatment initiation there was found to be significant improvement. We propose brodalumab as an effective treatment option for widespread ILVEN.
