Atypical secondary syphilis presentation in a patient with human immunodeficiency virus infection: a case report.

INTRODUCTION

Untreated syphilis may lead to severe complications. This infection has recently re-emerged in developed countries with a high number of cases coinfected with human immunodeficiency virus. In these patients, the skin lesions of secondary syphilis can be very atypical.

CASE PRESENTATION: We report the case of a 38-year-old Bulgarian homosexual man who was coinfected with human immunodeficiency virus and syphilis. His skin contained multiple extensive necrotic lesions with abundant purulent secretion that covered his face, lips, scalp, and torso. Initial clinical diagnoses included varicella pustulosa and staphylococcal dermatitis. Human immunodeficiency virus infection in our patient had been established 2 years earlier in prophylactic studies, but had not been treated. Due to lack of penicillin, he was successfully treated with ceftriaxone, and the skin lesions underwent complete reversal. He also began antiretroviral therapy, which resulted in a significant effect on his immune status. Three months after the onset of antiretroviral therapy, he also achieved optimal viral suppression.

CONCLUSION

This case emphasizes the importance of considering cutaneous secondary syphilis in the differential diagnosis of any inflammatory cutaneous disorder in individuals infected with human immunodeficiency virus.
