three additional animal lines which appear potentially to be excellent animal models for vitiligo are : the barred plymouth rock chicken which exhibits periodic degenerating melanocytes presumably due to a cytotoxic agent ( bowers et al , 1986 ) , the white leghorn chicken which exhibits preprogrammed melanocyte autophagocytosis ( jimbow et al , 1974 ) , and the duroc pig which exhibits spontaneous tumor regression and depigmentation ( hordinsky , personal communication ) .
