Abstract:
Lymphoma in the gastrointestinal tract most commonly occurs in the stomach, small intestine and around the ileocecal region. Usually gastrointestinal lymphoma occurs secondary to widespread nodal disease and is rarely found to be the primary site. Of the different types of lymphoma, diffuse large B-cell non-Hodgkin's lymphoma makes up the majority of lymphomas in the gastrointestinal tract. Primary colorectal lymphoma is even less common and accounts for 3% of all gastrointestinal lymphomas and to our knowledge, gastrointestinal lymphoma involving 2 different regions in the GI tract has not been discussed in the literature. Herein, we are presenting a rare case of diffuse large B-cell lymphoma presenting as a malignant mass in both the duodenum and ascending colon.

01:30Inflammatory Bowel Disease II: Crohn's Disease
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.

01:17Chronic Bowel Disorders: Introduction
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...
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...
01:15Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
