RESUMEN
This is the case of a 25-year-old patient, with the notion of unprotected sexual relations with multiple partners consulted for cholestatic icterus with pruritus evolving for 2 months. The general examination found an intense mucocutaneous icterus. The examination of the lymph nodes revealed multiple lymph nodes. A thoracic-abdominal-pelvic scanner showed peri-portal edema and adenopathies above and below the diaphragm without suspicious lesions. Biologically, there was acute cytolysis with ASAT at 1612IU/L, ALAT at 1506IU/L, and icteric cholestasis, the acute viral serologies and other autoantibodies were all negative. Given the presence of adenopathy and sexual risk factors, a syphilis serology was requested and was positive: a TPHA at 2560UI/L, and a VDRL at 1/32 UI/L. A liver biopsy was performed, which showed the presence, on immunohistochemistry, of anti-treponemal-pallidum antibodies. After eliminating all etiologies of cytolytic hepatitis, we retained the diagnosis of syphilitic hepatitis. Therapeutically, we started a treatment based on ceftriaxone 2g/dl with spectacular biological improvement at H48 of the beginning of treatment.
