Abstract:
Intestinal spirochetosis (IS) is an infectious gastrointestinal disease caused by Brachyspira bacteria. We detail an exceedingly rare case of IS with concomitant invasive colorectal adenocarcinoma (CRC) in a 58-year-old man presenting with abdominal discomfort and fever. Colonoscopic evaluation revealed abnormal-appearing, nodular cecal mucosa and a 35 mm rectosigmoid mass. Histopathology confirmed IS infection and CRC. Our case report is the first to detail IS diagnosed concurrently with colorectal cancer. It highlights the necessity of a high index of suspicion for IS in patients presenting with abdominal discomfort and endoscopic evidence of irregular nodular mucosa, particularly in the setting of suspected CRC. It further details potential pathophysiologic links between IS and colorectal malignancy.

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
