The object of this paper is merely to add to the previous statistics on extragenital chancres, the cases herein enumerated being those seen at the Barnard Free Skin and Cancer Hospital and the Washington University Dispensary. Included in this report for the interest they may add, but not included in the averages because of the factor of uncertainty in personal histories, are the locations of some extragenital lesions as given by patients who were first seen in advanced stages at the former hospital. These patients gave fairly definite histories of the extragenital lesions, but the lesions are listed separately because of the personal equation.
From August, 1905, to August, 1919, 225 patients have presented themselves at the Barnard Hospital dispensary with a chancre as the chief complaint, or with the chancre still in evidence. Of these, fiftyfive had extragenital primary sores, giving the rather high percentage of 24.5 per cent.,
