Intrahepatic cholestasis due to Treponema pallidum in an immunocompetent patient

Abstract

Hepatitis due to Treponema pallidum is a rare entity and its diagnosis represents a clinical challenge. Treponema pallidum should be considered as a presumptive etiology in all patients with acute liver disease, when other frequent causes have been ruled out. We present the case of a young, immunocompetent patient with elevated values in his liver tests, a cholestatic pattern, and maculopapular lesions on his palms and soles. Given his clinical picture, diagnostic tests, and response to the antimicrobial therapy, a diagnosis of cholestasis due to secondary syphilis has been established. It is important to include secondary syphilis within the possible causes of acute liver disease.
