Perianal itching may be eczema or a fungal infection, but syphilis cannot be ruled out.
Perianal itching is not a characteristic manifestation of syphilis. Perianal itching is a common symptom of perianal eczema or fungal infection. Clinically, perianal itching can occur alone or in combination with perianal moistness and erythema. You can go to the dermatology department of the hospital and have a fungal examination to help diagnose it.
If perianal itching occurs after high-risk sexual behavior and lesions similar to flat warts appear, it is necessary to go to the dermatology department of the hospital in a timely manner, and have blood tests for specific and non-specific syphilis spirochete antibodies in order to screen for syphilis.
The diagnosis of syphilis needs to be clarified by blood screening for syphilis antibodies, and syphilis cannot be diagnosed solely on the basis of clinical manifestations.
