Abstract:
Cancer of the appendix is an uncommon malignancy that is rarely diagnosed on colonoscopy. We present a case of incidentally discovered goblet cell adenocarcinoma of the appendix and the subsequent management. The patient initially presented with progressive epigastric pain in the setting of a family history of gastric cancer and personal history of colon polyps, for which surveillance was due. Bidirectional endoscopy was performed, from which biopsied tissue of an abnormal-appearing appendiceal orifice confirmed goblet cell adenocarcinoma. This case highlights the importance of identification of the appendiceal orifice in all colonoscopies and tissue sampling in cases of atypical-appearing anatomy.

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...
