Abstract:
We described a case of dyschromatosis symmetrica hereditaria in a 20-year old male patient who had spotty hyperpigmentation mingled with patches of hypopigmentation on the dorsal surfaces of both hands, feet., elbows and knees. In his family. the mother and elder brother were also affected by this disease. The histologic finding of the pigmented macule showed mild hyperkeratosis and marked increase of pigmentation at the basal cell layer, and that of the depigmented macule showed a decreased amount of melanin.
