Abstract
Piebaldism is a rare autosomal dominant disorder of pigmentation that is characterized by variable patches of depigmentation on the face, chest, abdomen, and extremities. We describe two cases of piebaldism, in whom the remarkable asymmetric distribution of the depigmented patches in a connected, contiguous pattern across the legs provides embryologic insights. This finding is not explained by the traditional theory that melanocytic migration only originates in the neural crest and progresses unilaterally down each leg. We propose that our cases, and other similar cases, can be explained by a recent theory of mesodermal melanocyte migration.
