Concurrent syphilis, gonorrhea, and monkeypox: A case report

Abstract

Documented cases of monkeypox virus outside of Africa are rare, but as of August 22, 2022, the CDC was tracking 18,101 cases in the United States. Monkeypox rash can easily mimic other sexually transmitted infections, which may occur concurrently. This case report describes a 36-year old Caucasian man who has sex with men. The patient came in for a routine history and physical examination and disclosed a perianal rash. The patient had a medical history significant for undertreated HIV, ankylosing spondylitis, and homelessness. On examination, he had multiple perianal deep-seated ulcers that were swabbed for monkeypox and herpes simplex virus 1 and 2. Samples were also collected for syphilis, chlamydia, and gonorrhea. The swabs were positive for monkeypox and pharyngeal gonorrhea. At subsequent blood draw, he was found to have elevated titers for syphilis and a positive QuantiFERON-TB gold test. In summary, this case is a clear example of an individual with concurrent monkeypox virus and other sexually and nonsexually transmitted infections, highlighting the importance of careful identification of risk factors and testing for monkeypox virus even when the clinical presentation may depict a common sexually transmitted infection, such as the herpes simplex virus.
