Acroqueratoelastoidosis de Costa: reporte de un caso esporádico

The acrokeratoelastoidosis of Costa is a rare genodermatosis of autosomal dominant inheritance with variable expressivity. It is characterized by the presence of multiple hyperkeratotic papules in the marginal zone of the hands and / or feet, which appears predominantly in childhood and early adulthood. It is generally asymptomatic and chronic. Its differential diagnosis from the rest of acrokeratodermias is a challenge for the physician; however, the histological finding of elastorhexis allows us to categorize it. We present a sporadic case of a young female patient, with clinical and histopathological characteristics typical of the disease.
