Solitary papular lesions on the penis in insufficiently treated early syphilis. A report of two cases.
Two cases of insufficiently treated early syphilis with solitary papular lesions on the penis are described. There seems to be a close resemblance between these cases and descriptions from the Salvarsan era concerning the occurrence of solitary papules located on or near the place of the healed primary syphilitic lesion, after insufficient treatment with Salvarsan.  Problems in diagnosing these cases are discussed.
