Among fifteen American and English books on pediatrics, hair plucking was mentioned in but three. In two of these it appeared in the index under the term "trichotillomania," which is not excessively helpful to the uninitiated. It was described in one of these books1 as "a rare nervous disease," mention being made of the fact that "Sutton reported a case in a boy of 14." Another author2 reported two cases, and a third3 included a brief description. The remaining twelve were silent. Thus it seems that hair plucking has not unduly intrigued the imagination of writers on the "bad habits" of childhood, and this is interesting, as the habit is not rare at all and I am sure that all pediatricians have seen it a number of times. I have in mind three cases, all of which occurred in boys under 3 years of age.
