title: [Piebaldism: ultrastructural study and pathogenic interpretation].
abstract: A case of "piebaldism" is studied under the electron microscope. The authors observe a great diminuation of melanocytes in the achromatic zones, contrasting with a hyperplasia of the Langerhans Cells. There also exists a large number of hyalin bodies, both intra-epidermic and dermic. The first seem to be formed on contact with degenerative mastocytes and Langerhans Cells, and could represent a way of elimination of these cells. As in certain previous cases, they found many mastocytes in the epidermis.
