Allow me to make a quotation from Kaposi1 as an excuse for the following paper: "No experimental proof has been offered that characteristic lupus vulgaris can be produced by inoculation of tubercle bacilli. The inoculation of lupus tissue and of the bacilli derived from it has given rise to inflammatory products, but not to lupus, nor has any clinical proof been found, unless we accept extremely careless statements. This is less true concerning a few published cases such as that of Besnier (lupus in a vaccination scar), Sachs (lupus after piercing the ear), etc. These and other similar, although less carefully observed cases, might demonstrate the occurrence of clinical lupus from inoculation of tubercle bacilli."
The cases to be related are not experimental proof, but rather examples of clinical lupus from probable inoculation of the tubercular germ. There is very little, if any, reason to consider one of the
