The material was obtained from necropsy subjects—from the chest, anteriorly, of a man dying of erysipelas and the arm of a negress who had been vaccinated nineteen days previously. I have not attempted to compile a comprehensive list of suppurative conditions in which metaplasia may occur, because the application of the finding was not to those diseases, but to the morbid cytology of sweat glands.
In both of these dermatoses, the inflammatory leukocytic exudate and congestion which are usual in severe acute inflammatory processes were present around all the appendages, and in the case of some of the sweat ducts and glands polymorphonuclears could even be found in the lumen. As regards the sweat duct cells, we are thus dealing reasonably with a reactive hyperplasia which is of the same order as that seen so often in the epidermal ones in chronic dermatoses and which was also present in this
