Dr. J.R. Sun at Department of Dermatology and Venerology, Peking University First Hospital, Beijing, China, and associates have reported a case of Malignant syphilis in a young man with HIV infection that has appeared in the British Journal of Dermatology.
Malignant syphilis is an uncommon manifestation of secondary syphilis, in which necrotic lesions may be associated with systemic signs and symptoms. Generally, it occurs in an immunosuppressed patient, mainly HIV-infected, but might be observed on those who have a normal immune response.
According to the history of the case, a 23‐year‐old man presented with a 2‐month history of recurrent fever and progressing skin ulcers with eschars on his face, trunk, and extremities. Treponemal serology test was positive and immunohistochemistry of his skin biopsy showed numerous spirochetes.
Additional results confirmed that he was infected with HIV, with a decreased CD4+ T‐cell count. A diagnosis of malignant syphilis associated with HIV infection was finally made.
