Reviewing sebaceous adenomas in 1948, Lever listed 2 varieties of sebaceous nevi: Jadassohn's nevus sebaceus and Pringle's adenoma sebaceum.1 In his textbook2 Lever added 2 more sebaceous nevi to his list of organic hamartomas (organic nevi) of sebaceous differentiation: senile sebaceous nevus and Fordyce's disease. Woolhandler and Becker listed 2 other varieties of sebaceous tumors which appear, from their report and one microscopic photograph, well enough differentiated to be classified as sebaceous nevi: keratotic adenoma sebaceum and nevus pigmentosus et sebaceus.3 Thus there would appear to be at least 6 varieties of sebaceous nevi reported to date. This report concerns an interesting case which does not fit any of the above categories and yet seems definitely to fall within the general group of well differentiated sebaceous nevi.
