Acquired brachial cutaneous dyschromatosis (ABCD) is an acquired disorder of pigmentary change that presents as chronic, asymptomatic, geographic-shaped, gray-brown patches, consisting of mixed hyper and hypopigmented macules on the dorsal aspect of the forearms. We report a case of a 40-year-old male who presented with asymptomatic, multiple brown-colored macules on the outer aspects of both arms. He had no history of hypertension and had never taken angiotensin converting enzyme inhibitors. He also denied chronic sun exposure history. Histologic examination demonstrated epidermal atrophy, increased basal layer pigmentation, and several telangiectatic vessels in the upper dermis. Solar elastosis was not remarkable. The patient’s clinical and histopathologic features were consistent with a diagnosis of ABCD. Poikiloderma of Civatte, melasma, acquired bilateral telangiectatic macules and other pigmentary disorders should be considered in the differential diagnosis of ABCD. Herein, we report a case of ABCD in a middle-aged male without hypertension and medication.
