Michelin tire baby syndrome: familial constriction bands during infancy and early childhood in four generations.

We report on an infant with an unusual pattern of transitory familial constriction bands distributed symmetrically and circumferentially over the neck, forearms, and lower legs. Family history showed the occurrence of similar bands among individuals in 4 generations transmitted as an autosomal dominant trait. Neck and limb distribution in the other affected family members was also symmetrical and circumferential, with spontaneous resolution taking place during childhood. This case represents another example of the Michelin tire baby syndrome, also known as multiple benign circumferential skin creases of the limbs, and further demonstrates its autosomal dominant mode of inheritance.
