Abstract:
A 69 year-old man presented to his primary care physician with abdominal discomfort. Medical history was notable for diabetes, chronic obstructive pulmonary disease with recent (one week prior) steroid use and hypertension. Surgical history was significant for a remote sigmoid hemicolectomy for diverticulitis with a synthetic mesh abdominal repair. He was admitted to the hospital for suspected gastroparesis. An upper GI series showed a distended stomach with delayed gastric motility. He underwent esophagogastroduodenoscopy and a duodenal biopsy was taken. He remained afebrile but had an elevated white blood cell count of 19.1 x 103/mcL (4.5 - 11.0 x 103/mcL) with 28.8 percent eosinophils on differential. Microscopic images of the duodenal biopsy are shown below.

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.
