“…This clinical variant has followed ritual circumcision (5), mouth-to-mouth resuscitation [6], inoculation of labora tory guinea pigs [7], injections with poorly sterilized nee dles [8], ear piercing [9], intramuscular injections given by a nurse with active tuberculosis [10], tattooing [11], insect bites 112], sexual intercourse leading to venereal inocula tion [13][14][15] and venipuncture in an infant [16], Nowadays, tuberculous chancre, just as other clinical forms of cuta neous tuberculosis, has decreased in frequency because of the improvement of the standard of living, availability of effective antituberculous antibiotics and elimination of infected milk herds [8,17], thus it has been almost restricted to those whose occupations resulted in occasional exposure to M. tuberculosis: autopsy staff, laboratory workers, surgeons, anatomists, veterinarians, farmers and butchers [17][18][19].…”
