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. The patient was treated conservatively and 10 days later, new endoscopy showed complete disappearance of ulcerated mass, and new biopsies confirmed the initial diagnosis. Awareness and early diagnosis of 'mass forming' entity of ischemic colitis is very essential in order to carry out appropriate treatment and avoid severe complications.

Background/aims: Portal vein thrombosis (PVT) frequently occurs in patients with inflammatory bowel disease (IBD), particularly when influenced by factors such as abdominal infections, IBD flare-ups, or surgical procedures. The implications of PVT range from immediate issues such as intestinal ischemia to long-term concerns including portal hypertension and its complications. However, there is a notable gap in comprehensive studies on PVT in IBD, especially with the increasing incidence of IBD in Asia.

Article Synopsis
- Vasculitides cause inflammation of blood vessel walls and mesenteric vasculitis (MV) specifically affects the blood vessels in the gastrointestinal tract, often linked to systemic inflammation but can also occur alone.
- Common symptoms of MV include nausea, abdominal pain, diarrhea, and rectal bleeding, which complicate diagnosis and can lead to serious health risks if missed.
- The review highlights the need for timely diagnosis and appropriate treatment to avoid unnecessary surgeries, while also pointing out challenges in distinguishing MV from similar gastrointestinal conditions and the lack of clear diagnostic criteria in existing literature.
