Esophageal syphilis

Syphilis is a chronic infectious disease caused by Treponema pallidum and is a type of sexually transmitted disease. It can be congenital or acquired. Congenital syphilis is transmitted from the mother, while acquired syphilis is mainly transmitted through sexual contact. The disease has a long course and progresses slowly, mainly affecting the skin and mucous membranes. In the late stage, it may involve the heart, central nervous system, bones, and visceral organs, and the esophagus may also be affected.
