Prototype of all lichenoid eruptions is lichen planus. Histologically lichenoid eruption showing basal cell liquefaction or necrotic keratinocytes are dermatomyositis, DLE, drug eruptions fixed, erythema multiforme, graft versus host diseaseQ, lichen planusQ, lichen nitidus, lichen purpuricus aureus, lichen striatus, lichenoid keratosis, lichenoid drug eruptions, lichen planus-lupus erythematosus overlap syndrome, lichen planus, pemphigoides, keratosis lichenoides chronica Nekams disease, pityriasis lichenoides, poikolodermas and viral exanthems.
