Morphoea in three siblings.

Atrophoderma of Pasini and Pierini (APP) is an uncommon form of localized morphoea that occurs as superficial, hyperpigmented plaques distributed mainly on the trunk and proximal part of the limbs. There is little information about the influence of genetic and environmental factors on disease susceptibility and expression for localized scleroderma, although APP familial cases have been reported. We report three siblings without a family history of autoimmune disease presenting cutaneous lesions suggesting morphoea (APP variant).
