Cases of coexistent lichen sclerosus et artrophicus and morphea have been reported. It is controversial that both diseases are single disease-spectrum or entirely separated. We encounterd a forty five year old female with a hypopigmented firm plaque on the left neck. Its histologic feature showed compact orthokeratosis, follicular plugging, atrophy of the stratum malpighii with vacuolar alteration of basal layer, and homogenization of the collagen in the upper dermis (lichen sclerosus et atrophicus). Increased thick collagen bundles were seen in the lower dermis (morphea).
