A Case of Atypical Dyschromatosis of Unilateral Dermatomal Distribution / 대한피부과학회지

We report a 19-year-old patient with numerous mottled hyperpigmented and hypopigmented macules over his left upper and lower extremities and left side of trunk. which are unilateral and dermatomal distribution. He has had these macules for 5 years. The family history does not revealed similar pigmentary changes. The pigmented macules resemble those of dyschromatosis universalis herediteria or dyschromatosis symmetrica hereditaria. In addition, the histopathologic features were also simlar to those reported in dyschromatosis, but clinically our case had unilateral dermatomal distribution which was different from typical dyschromatosis. Therefore, We think our case as atypjcal dyschromatosis
