Patients with lichen simplex chronicus usually describe stable pruritic plaques on one or more areas; however, thickening of the skin occurs on any location that the patient can reach, including the following:

  • Scalp [16]

  • Nape of neck

  • Extensor forearms and elbows

  • Vulva and scrotum [6, 17, 18, 19, 20]

  • Upper medial thighs, knees, lower legs, and ankles
