Extragenital Syphilitic Chancre. Presented by Dr. Irving R. Bancroft.
L. N., a man aged 32, engaged in a fist fight about two months ago and struck his opponent in the mouth. His knuckle was abrased by the teeth of his opponent. The wound did not heal but became swollen and appeared to contain pus although no pus was found. One week ago the lesion was still present and a distinct and typical rash of secondary syphilis had developed. A dark field examination showed Spirochaeta pallida.
The patient has received two injections of a bismuth preparation and two injections of arsphenamine. The eruption has practically disappeared.
Dr. E. D. Lovejoy: A peculiar thing about primary lesions occurring in abrasions made by a human bite is the fact that the infection is limited to one abrasion. Others are immune, regardless of how closely located they may be.
