Rectal ischemia causes mass formation, masquerading as rectal cancer.

Rectal ischemia rarely occurs because of the rich vascular supply of the rectum, while endoscopic presentation of ischemic colitis always is not distinct and can uncommonly mimic malignant neoplasm. We present a case of a rectal ischemia, which presented with haematochezia and proctoscopy revealed a large ulcerating mass, masquerading as rectal cancer and obstructed the lumen of rectum. However, histological examinations showed only features for ischemic colitis and no evidence for malignancy.

Double Pylorus: Report of a Case With Endoscopic Follow-Up and Review of the Literature.

Double pylorus is a rare endoscopic finding that has been reported in 0.001% to 0.4% of upper gastrointestinal endoscopies and can be either congenital or acquired.

Rectal ischemia mimicked tumor mass.

Ischemic proctitis is a rare disease which is usually encountered in elderly with comorbidities. We present a case of an 80-year old man with severe coronary disease who presented with severe hematochezia and hypotension. Endoscopy revealed a rectal mass 3-4 cm above the dental line and rectosigmoid mucosal inflammation compatible with ischemic colitis.
