title: [Malignant syphilis in an HIV-infected patient].
abstract: Patients with HIV infection may develop common diseases with atypical clinical features. HIV infection may change the classic clinical course of syphilis and increase the incidence of a subtype of secondary syphilis named malignant syphilis. A homosexual patient with HIV infection consulted us about a one-month history of general malaise and widespread cutaneous ulcerative lesions, some with thick hemorrhagic crusts. Serology for syphilis was positive at high titers. Based on clinical, histological and serological findings, a diagnosis of malignant syphilis was made and the patient started treatment with penicillin G benzathine with progressive resolution of lesions. Malignant syphilis is a rare subtype of secondary syphilis that presents special clinical and histological features and has been associated with several processes characterized by variable degrees of immunosuppression. It is necessary to take into account this entity among the possible diagnoses in HIV-infected patients with cutaneous lesions.
