title: [Nodular granuloma of the lip. An unusual manifestation of secondary syphilis].
abstract: Syphilis is a sexually transmitted disease caused by Treponema pallidum which evolves through three overlapping stages. A 50-year-old woman presented with an expanding painless granulomatous nodule on her lower lip in combination with a maculo-papular exanthem. Both serologic studies and microscopic examination indicated an infection with Treponema pallidum. This case shows an unusual granulomatous nodular presentation of syphilis on the lower lip, emphasizing the variable clinical and histological manifestations syphilis, which shows an increasing number of new infections worldwide in recent years.
