Mpox is a venereological differential diagnosis

Abstract

A 34-year-old man, homosexual, came to the clinic of venerology due to severe perianal pain. When examinated, small, eroded vesicles were found perianally. This was interpreted as a primary herpes infection. At the follow-up visit, several vesicular and papular elements were now present on the body. The patient tested positive for mpox. This case confirms that mpox is a relevant differential diagnose in venerology in Denmark.
