Generally speaking, patients do not know much about their external genital organs and usually pay little attention to them. Once they visit the dermatology department because of unidentified swellings on their external genital organs, most of them have a history of smut, and occasionally after cheating, they refer to the one-sided knowledge provided by the Internet or the media, suspecting that they are infected with STDs and are blindly diagnosed and treated. Doctors should not think in a stereotypical way, but should be responsible and comprehensive in their inquiries and carefully examine the specialist situation, and should not take anything for granted.
