Pyloric Gland Metaplasia of the Ileocecal Valve: Clinicopathologic Correlates of Inflammatory Bowel Disease
نویسندگان
چکیده
Pyloric gland metaplasia of the ileocecal valve, in the setting of Crohn's disease, is an unusual clinical entity. Though its etiology and pathogenesis remains unclear, metaplastic changes have been associated with chronic inflammation and inflammatory bowel disease. Herein, we report a case of a 23-year-old male who presented for surveillance colonoscopy after being diagnosed with Crohn's disease four years ago. Diagnostic colonoscopy revealed stenosis of the ileocecal valve as well as a 5 mm polypoid circumferential non-obstructing lesion. Excisional biopsy followed by histopathology revealed pyloric metaplasia and non-necrotizing epithelioid cell granuloma. We discuss the clinical significance of pyloric gland metaplasia of the ileocecal valve in the context of inflammatory bowel disease.

Background: Total colectomy is used in children with total colonic aganglionosis, Ulcerative colitis (UC) and familial adenomatous polyposis (FAP). The purpose of this study was to maintain ileocecal valve and rectal-sparing surgery for the prevention of fecal incontinence in these children. Methods: From1990 to 2011, 14 children with diagnosis of UC, FAP and Hirschsprung’s disease were operat...

Gastritis is a histopathologic diagnosis, which correlates poorly with both clinical symptoms of non-ulcer dyspepsia and endoscopic abnormalities. Worldwide, most cases of gastritis are due to Helicobacter pylori and are characterized by a diffuse superficial antral gastritis. Chronic inflammatory cells and lymphoid follicles are present in the lamina propria. Neutrophils are present in the sur...

Patients with inflammatory bowel disease have significantly increased in recent decades in Korea. Intestinal tuberculosis (ITB) and intestinal Behcet's disease (BD), which should be differentiated from Crohn's disease (CD), are more frequent in Korea than in the West. Thus, the accurate diagnosis of these inflammatory diseases is problematic in Korea and clinicians should fully understand their...

Benign ileocecal valve hypertrophy is a rare cause for intestinal obstruction. We describe a 51-year-old female with clinical and imaging presentation of chronic small-bowel obstruction. The patient was operated on, and a limited thickening of the ileocecal bowel wall causing intestinal obstruction was found. A right hemicolectomy was performed. On microscopic examination, severe fibrosis with ...

Mucosal biopsy specimens from the ileal reservoirs of 92 patients who had undergone restorative proctocolectomy (12 with familial adenomatous polyposis, 78 with ulcerative colitis, and two with functional bowel disease) were studied. Chronic inflammation was found in almost all, as was villous atrophy of varying severity. Other changes included pyloric metaplasia and mucosal prolapse. Acute inf...
