This report describes a small group of unusual cutaneous neoplasms, probably derived from hair germ, which (1) recapitulate the development of the hair follicle; (2) illustrate an inductive relationship between epithelial and mesenchymal components analogous to that between hair bulb and dermal papilla; (3) demonstrate a topographical organization similar to that seen in the skin; and (4) do not correspond to neoplasms previously described. MaterialTwo of the three neoplasms (cases 1 and 2) were obtained from the files of the Department of Pathology in The University of Michigan; the third was acquired through the courtesy of Professor
