As a rule, the boil in this location runs its usual course in no way different from similar lesions on other parts of the body. Recently, among the 3,200 patients at the Pennhurst State School, Spring City, Pa., we have observed twentyeight patients in whom furuncles on the scalp have been followed by temporary noncicatrizing alopecia about the site of the infection. Of these, we were able to follow 20 cases without interruption from the appearance of the boil to the complete regrowth of hair, and our observations on this group will be reported here. We have designated this temporary hair loss as post-furuncular alopecia.
