Resumen: Lichen aureus is a rare pigmented purpuric dermatosis. We present an unusual case because of the pediatric age and the great number of lesions with zosteriform distribution. He is a 10-yearold boy, with a brownish, smaller than 1 cm, sharp edges, lichenified surface, asymptomatic macule, over the inner aspect of the left leg with a zosteriform distribution. The histology showed a band-like inflammatory infiltrate in the superficial dermis, composed of lymphocytes, histiocytes, erythrocytes and haemosiderin. He was diagnosed with zosteriform lichen aureus and was treated with topical mometasone furoate during 3 weeks resulting in partial lightening of the macules. Lesions have remained 2 years later, and new ones have appeared in the ipsilateral ankle. We must consider differential diagnosis with other pigmented purpuric dermatitis and pigmented purpuric mycosis fungoides. There are many therapeutic options and it tends to disappear spontaneously, so new studies are necessary.
