Abstract:
A cholecystocutaneous fistula is a type of external biliary fistula that occurs when there is an abnormal connection between the gallbladder and skin. We report the first case of a cholecystocutaneous fistula that occurred in association with the development of lymphoma in the gallbladder. A 76-year-old woman who was under observation for follicular lymphoma with a low tumor burden presented with fatigue and abdominal pain. Imaging studies revealed cholecystitis associated with an abdominal subcutaneous abscess, and lymphoma transformation was confirmed by a lymph node biopsy. Edwardsiella tarda was cultured from both the abdominal subcutaneous abscess and percutaneous transhepatic gallbladder drainage, demonstrating cholecystocutaneous fistula, and open cholecystectomy revealed lymphoma cell infiltration into the gallbladder. Our case showed unique complications, and its successful management was associated with aggressive lymphoma development.

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

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...
