“…Linear LP can follow a ‘blaschkoid' distribution in adults but is also described in a case report of a child [12,13,14,15]. 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].…”
