Abstract
A 61-year-old man had multiple lichen planus. There were brownish papules on the bilateral pretibial regions and were considered to be common type lichen planus. He had a little finger tip sized to thumb tip sized erythematous brownish annular lesions with desquamation, itching and a slightly atrophic center on the scar of central region of the abdomen and left inguinal region. These were lichen planus annularis. He had a linear, similar lesion on the left axillar region to the inner aspect of his upper arm and this was lichen planus linearis. Histopathologically, typical lichen planus was noted. The annular lesions were not in papules form, rather they first formed a ring plaque. This was considered to be a rare case of lichen planus. If the basal cell layer is destroyed as the result of outside influences, then the epidermis will show a lichenoid tissue reaction.
