Abstract:
Malignant syphilis is an uncommon form of secondary syphilis associated with HIV infection. Clinically, it is characterized by necrotic nodules and generalized ulcerated lesions. We present 4 cases of malignant syphilis diagnosed after evaluating syphilis cases diagnosed at our hospital between 2012 and 2016. We describe the epidemiologic, clinical, histiopathologic, and serologic characteristics of malignant syphilis and explore its response to treatment and association with HIV infection. Although malignant syphilis is uncommon, there has been an increase in the number of cases published in recent years, particularly in young HIV-positive patients. Malignant syphilis must be contemplated in the differential diagnosis of HIV patients with ulcerated, necrotic lesions.
