Presentaciones poco comunes y peligros de la sífilis secundaria: periosteitis, tenosinovitis y anomalías hepáticas.

We herein describe two cases of secondary syphilis in patients with human immunodeficiency virus (HIV) infection with an unusual presentation, a diffuse polyostotic periosteitis. Patients referred mainly intense bone pain. Other relevant aspects of the clinical pictures were flexor tenosynovitis and hepatic abnormalities. Given the persistence of symptoms, the treatment duration performed was different from most described in literature. However, although more slowly than expected, both obtained a favorable clinical response after treatment with benzathine penicillin G.
