Lues maligna is a rare noduloulcerative form of secondary syphilis, an infection by the spirochete T. pallidum.
- Patients usually do not have the typical palmoplantar involvement of secondary syphilis.
- Most reported cases are associated with HIV infection.
A prodrome of fever, headache, and myalgia is followed by a papulopustular eruption that ultimately forms necrotic ulcers and crusted lesions, some with rupiod scale. Patients may be severely ill. It is more common in HIV-infected patients, but may occur in non-HIV patients as well.
RPR or other serologic testing as well as special stains of skin biopsy confirms diagnosis.
An HIV test should be ordered. See secondary syphilis for treatment.
