Introduction:
Primary lymphoma of the colon and rectum is an uncommon form of cancer comprising less than 0.5% of all colorectal tumors combined. Typically, extra nodal lymphomas manifest in the gastrointestinal tract, with non - Hodgkin lymphoma being the most frequent subtype and the stomach being the most common location.
Case Presentation:
70 year old female with medical history of osteoarthritis and osteoporosis was evaluated for bilateral leg rash and thrombocytopenia. Eventual work up revealed cecal mass but inconclusive findings on colonoscopy. She underwent hemicolectomy due to persistent thrombocytopenia with histopathology positive for primary Diffuse Large B-cell Lymphoma (DLBCL). She underwent chemotherapy with complete resolution of her mass and lymphadenopathy.
Conclusion:
We are presenting a rare case of Non - Hodgkin lymphoma in the colon. This disease can show up with unclear symptoms, so it's important to use different types of imaging and pathology tests to identify the specific type of lymphoma. The main treatment for this type of cancer involves using chemotherapy and radiation therapy.

01:27Inflammatory 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...

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, 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...
