RESUMO
Anetoderma or Macular atrophy is a rare cutaneous disorder showing local atrophy and macular discoloration related to a local dermal defect of elastic tissiie without any other apparent change in the skin, which may show familial occurrence, called familial anetoderma. A 13-year-old female complained 3-year history of multiple asyrnptomatic atrophic macules on the trunk and both lower extremities, especially on both this. Elastic stain of skin lesion showed decrease of lastic tissue in the dermis. No other syst mic abnormalities were found on phisical examination. Her sister had same skin lesion on lower extremities and both buttocks, and had no ther systemic abnormalities. Despite infrequent occurence, the development of anetoderma among familial members possibly represents a congcnital defect of elastin. Because variou ocular, bony, cardiac, and gastrointestinal abnormalilies have been reported in familial anetoilerma, long-term follow up would be necessary.
