Summary
We report a rare case of high-grade B-cell lymphoma presenting as a large mesenteric mass in an active duty service member. This hematologic malignancy was diagnosed via colonoscopy, highlighting an uncommon presentation.
Area of Science:
- Gastroenterology
- Oncology
- Hematology
Background:
- Colonic masses encompass benign and malignant conditions, with adenocarcinoma being the most prevalent cancer.
- Lymphoma, though common in military personnel, is rarely diagnosed during colonoscopy.
Purpose of the Study:
- To present a rare case of high-grade B-cell lymphoma diagnosed via colonoscopy in an active duty service member.
- To highlight an unusual presentation of lymphoma involving a large mesenteric mass with cecal extension.
Main Methods:
- Endoscopic examination of the colon.
- Histopathological analysis of tissue samples obtained during endoscopy.
Main Results:
- A large mesenteric mass with extension into the cecum was identified.
- The mass was diagnosed as high-grade B-cell lymphoma.
Conclusions:
- High-grade B-cell lymphoma can present as a large mesenteric mass with colonic involvement.
- Colonoscopy can be a diagnostic tool for rare presentations of lymphoma in the gastrointestinal tract.

01:17Chronic Bowel Disorders: Introduction
388
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Introduction
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...

Introduction
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...

01:27Histology of the Small Intestine
520
The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
