Reticulated acropigmentation of Dohi(RAD) is a dyschromic disorder that has an autosomal dominant pattern of inheritance. RAD is characterized by the intermingled hyperpigmented and hypopigmented macules and its bilaterally symmetrical distribution on the back of the hands and feet, wrists, knees, and elbows. Histologically, there is excess of melanin in the basal layer alternating with others in which melanin was totally absent. We report a case of reticulated acropigmentation of Dohi developed sporadically with typical clinical and pathological features. (Korean J Dermatol 2001;39 (1): 71~74)
