Plasmablastic lymphoma (PBL) is a rare and aggressive B-cell lymphoma with a poor prognosis and is typically linked to human immunodeficiency virus (HIV)-related immunodeficiency. PBL associated with ulcerative colitis (UC) is an extremely rare condition. We report the case of a 63-year-old HIV-negative woman with UC who developed colonic PBL after long-term mesalazine and budesonide treatment. She achieved complete remission following chemotherapy and abdominal radiotherapy, with no recurrence for more than three years. To our knowledge, this is the fourth reported case of UC-associated PBL and demonstrates the longest survival. Chemoradiotherapy may be an effective treatment for localized PBL.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
Inflammatory Bowel Disease I: Ulcerative Colitis
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...
