AI Article Synopsis
- PR bleeding in elderly patients often raises concerns for colonic cancer, especially when accompanied by changes in bowel habits without prior symptoms.
- A case study revealed that the cause of bleeding was actually a rare tumor called caecal schwannoma.
- Diagnosing caecal schwannoma is challenging, as endoscopic biopsies may not yield sufficient samples, making immunohistochemistry crucial for accurate diagnosis.
Article Abstract
The presence of per rectal (PR) bleeding in elderly people usually alerts us to the possibility of colonic malignancy, particularly if a concomitant altered bowel habit is present, without a history of the symptom. We present a case where the cause of PR bleeding turned out to be a caecal schwannoma. Caecal schwannoma is a rare tumour of the gastrointestinal tract of mesenchymal origin and diagnosis prior to radical surgical resection is difficult. Endoscopic biopsy often fails to provide an adequate specimen and immunohistochemistry is essential to the diagnosis.
