Abstract:
Gastrointestinal stromal tumors (GISTs) are uncommon tumors typically found in the stomach, with an even rarer appearance in the jejunum. These tumors are often discovered incidentally, given their nonspecific presentation. We present a case of chronic iron deficiency anemia in a patient with symptomatic GIST involving the proximal jejunum requiring robot-assisted resection with primary anastomosis. Pathological examination of the excised GIST revealed positive immunoreactivity for cKIT, DOG1, and CD37. This case highlights the importance of considering GIST as a differential diagnosis for chronic anemia and emphasizes the critical role of CT imaging in its detection and management.

Inflammatory 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.
