title: A mixed infection of syphilis and chancroid.
abstract: The clinical differentiation between a hard chancre and a soft chancre is well known to dermatologists. We present a patient with both a hard and a soft chancre developing on the penis. Thorough investigational studies should be made of all patients with venereal disease to determine whether more than one venereal disease is present.
