Abstract
None:
Anastomotic inflammatory polyps are a known source of gastrointestinal bleeding in patients who have undergone bowel resection, but an anastomotic spindle cell sarcoma with myogenic differentiation has never been reported. We present the case of a patient with occult gastrointestinal bleeding 6 years after an ileocolic resection for an incarcerated hernia and discuss surveillance in patients with these rare polyps.
