A Case of Multiple Lichen Striatus / 대한피부과학회지

ABSTRACT

Lichen striatus is an uncommon, self-limited, unilateral, linear dermatosis of unknown etiology, ordinarily seen in children from 5 to 15 years of age. Clinically lichen striatus consists of a continuous or interrupted band of discrete or confluent, flat-topped, smooth or scaly papules. Multiple lesions are so rare that only 3 cases have been reported in the Korean literature. We reported a rare case of multiple lichen striatus in a 10-year-old girl. She had linear erythematous papules and brownish macules on the lower back, left shoulder, left chest, and left axillar area. The biopsy revealed that spongiosis and vacuolar degeneration in the epidermis, a lichenoid inflammatory infiltrate in the upper dermis and a dense lymphocytic infiltrate around the eccrine glands, ducts and hair follicles. The patient was treated with topical steroid. The lesions disappeared with minor hypopigmentation after 4 months.
