RESUMO
Pigmented purpuric dermatoses are chronic and relapsing disorders characterized by a symmetrical rash of petechial and pigmentary macules, mainly confined to the lower limbs. Purpura annularis telangiectodes of Majocchi is a less common variant of Pigmented purpuric dermatoses characterized by punctate telangiectatic macules progressing to annular, hyperpigmented patches with central clearing and infrequent atrophy. A 12 year-old girl presented with asymptomatic round to oval reddish brown macules, present symmetrically over her lower and upper limbs for 3 years. Few lesions were annular in shape. Biopsy from the lesion was compatible with Pigmented purpuric dermatoses. On the basis of clinical and histopathological findings, a diagnosis of Purpura annularis telangiectodes of Majocchi was made. The patient began phototherapy thrice a week and showed excellent response.
