A Case for Diagnosis. Erythema Multiforme or Syphilis? Presented by Dr. Sawyer.
Mr. T., first seen in May, 1921, gave a history of having had a chancre and gonorrhea one year before, appearing one week after exposure. He said a Wassermann test was made and found positive. No secondary symptoms appeared. He had had six injections of arsphenamine and eight of mercury. The Wassermann test in 1921 was negative. On March 23, 1926, I saw him with the present condition. He gave the following history: About a month before a rash began on the forehead and arms and spread to the rest of the body and legs. The Wassermann test was now negative. On March 30, he was put on potassium iodide. The patient now shows a raised, ham-colored, maculopapular rash on the entire body. There is also one open granular lesion on the instep of the left foot.
