The purpose of this paper is to add to the scant literature on the subject of twins one of whom has a positive and the other a negative serologic reaction for syphilis. I believe that this report is the first one in American literature in which twins who have been proved to be identical by the most exacting anthropometric values and finger and palm prints had dissimilar serologic reactions.
REPORT OF A CASE
A. R., a 19 year old Portuguese Negro, reported to the outpatient department of the Boston City Hospital on July 1, 1938 for a routine check-up. His father had received treatment for tertiary syphilis since August 1936 and his mother for late, latent syphilis since June 1938. There were 2 older siblings, a brother 35 years of age, who had not been examined, and a sister of 25, who was treated for secondary syphilis a few years
