Hereditary symmetrical dyschromatosis (Q98794): Difference between revisions

Hereditary symmetrical dyschromatosis is an autosomal recessive pigmentary disorder characterised by hypo- and hyperpigmented macules affecting predominantly the dorsal surfaces of the hands and feet. On the face the lesions resemble ephelides and no hypopigmentation appears. The condition is commoner in individuals of oriental origin. It develops during infancy and early childhood and persists into adulthood.
