“…Zosteriform LP follows dermatomal lines and is thought to be an isotopic response to herpes zoster or at least showing antigens against varicella zoster virus in lesional skin [16,17,18]. Lichen planus pigmentosus-inversus is suggested to be a rare variant of LP limited to intertriginous regions and seems to have a short inflammatory phase with fast transformation into a long noninflammatory regressive phase with brown, nonpruritic, small inflammatory macules; scaling is limited [19,20,21,22,23,24,25]. Only one case of coexistence of classic LP and lichen planus pigmentosus-inversus has been described [26].…”
