Rare case of syphilis presenting with labial chancre

Syphilis is a chronic inflammatory disease which is caused by the spirochete <i>Treponema pallidum</i> (<i>T. pallidum</i>) and is often sexually transmitted. The primary stage in syphilis classically presents with a painless ulcer which is evident in the genital area in more than 90% of patients and is commonly called as chancre. Extra genital chancres may differ from the classic ones based on the port of entry of the organism, in terms of localization, size, depth, base and edges thus, they may cause diagnostic problems.
