[Late secondary syphilis with ulceration of the tongue during HIV coinfection: case report].
With the continuing rise of syphilis incidence, late stages and atypical courses with HIV-coinfection can be expected. A 45 year old HIV infected male presented with an unusual manifestation of late secondary syphilis on the tongue, which was first diagnosed as a squamous cell carcinoma but cleared after therapy with penicillin. ⋯ A TPHA test was negative due to a prozone phenomenon. With this case, we would like to emphasize the formerly well known relationship between the lesions of tertiary syphilis on the tongue and development of secondary carcinoma.
