Reduplication of the involuntary muscular fibers of the skin to the degree of tumor formation is probably one of the rarest conditions encountered in dermatology, if the limited number of accepted cases thus far reported in the literature is duly considered. It is more rarely encountered if Besnier's1 commonly accepted classification is observed and those cases which primarily spring from subcutaneous muscular tissue, the dartos, labia, mamma, etc., the so-called dartoic myomata, which are essentially of surgical importance, are properly excluded. Radcliffe Crocker2 states that his case is the eleventh clearly defined instance in the literature and accords value to the two additional cases of Wolters'3 doubtful classification. Leslie Roberts4 asserts in 1900 that his additional case constitutes the fifteenth well defined instance. There have been but few cases reported in recent years, and Huldschinsky5 maintains that his constitutes the sixteenth additional case.
