Abstract: The morphologic changes in the scalp which characterizes cutis vertics gyrata was first described by Robert1 in 1848 and McDowell2 and Cown3 in microcephalic idiots. In 1906 Judassohn4 called to the attention of dermatologists the condition was given the name as cutis vertics gyrata by Unna5. Fisher stated the belief that true cutis verticis gyrata occurs as a developmental anomaly, probably atavistic in type, representing a reversion to a lower form of life in which the muscles of the scalp could move at will. This is probably the type originally described as present in microcephalic idiots.
