Juvenile Elastoma (Weidman)

Abstract
Two cases of juvenile elastoma (nevus elasticus in disseminated tumors) were histologically and ultrastructurally investigated using light microscopy and EM. The predominant components of this disseminated dysembryoplasia are abnormal elastic fibers. Both cases showed numerous large elastic fibers with an abundant background matrix. The elastic microfibrils were replaced by granular material. In 1 case, most of the abnormal elastic units remained isolated without forming elastic fibers.
