Resurgence of syphilis, the great imitator.

Syphilis, one of the earliest diseases to be discovered in humans, still remains an enigma when it comes to its myriad manifestations and changing epidemiological profiles. There has been a surge in cases in the last few decades due to various factors. The human immunodeficiency virus (HIV) epidemics, global travel, increased incidence of male to male sexually transmitted diseases, online relationships culminating in casual sex are few of the important factors. Increased awareness could also be a factor for increased diagnosis. The multitude of clinical features especially when it comes to secondary syphilis and the rare tertiary manifestations, which can mimic various systemic disorders still pose a diagnostic challenge to the best of venereologists and physicians. This review aims to discuss the causes of resurgence in syphilis and few recent developments in pathogenesis, which could have led to this resurgence.
