Primary Syphilis of the Anorectal Region

The regression of syphilis after the second world war mainly ceased during the years 1954–1957; since then the disease has again increased considerably throughout the whole world. According to Schmid (1960) venereal diseases, especially syphilis must be considered as the diagnosis behind anal symptoms. Schmid therefore stresses that primary syphilis has to be excluded before haemorrhoids, fissures, pruritus ani are treated.
