Syphilis is a chronic, classic sexually transmitted disease caused by Treponema pallidum, which can invade almost all organs of the body and produce various symptoms and signs. Although there are some cases of colorectal bleeding caused by syphilis, small intestinal bleeding caused by syphilis is still rare.
A 58-year-old man had experienced recurrent abdominal pain and melena for 3 years. Repeated gastroenteroscopy and computed tomography angiography examinations failed to find bleeding lesions. During the same admission, multiple intestinal ulcers were found by capsule endoscopy, and syphilis was also diagnosed. With a history of atrial fibrillation and chronic pancreatitis, he had undergone mitral valve replacement and tricuspid valvuloplasty for valvular heart disease. After anti-syphilis treatment, the melena and abdominal pain disappeared and his hemoglobin gradually increased. It is considered that gastrointestinal bleeding, chronic pancreatitis, atrial fibrillation, and heart valvular disease may have been caused by syphilis.
This case report found that syphilis can mimic systemic disease and cause intestinal bleeding. In addition, treatment of the disease requires both sexual partners to be treated. Finally, although syphilis is easy to treat, it is more important to consider that bleeding could be caused by syphilis.
Core Tip: Syphilis is considered a sexually transmitted disease, which can affect all systems of the body and cause multiple clinical signs and symptoms. We report a rare case of gastrointestinal hemorrhage caused by Treponema pallidum. The case occurred in an adult male patient. The patient has not only suffered from atrial fibrillation, heart valvular disease, chronic pancreatitis, etc. for more than 10 years, but has also undergone heart valve replacement surgery. In recent years, the patient experienced recurrent unexplained gastrointestinal bleeding. Finally, based on careful analysis, syphilis was identified as the cause of intestinal ulcers that eventually led to gastrointestinal bleeding. This case shows that syphilis is a systemic disease and that it is important to treat syphilis as a couple.
