Microscopic Description -- Severe Abdominal Pain
Segments of bowel are grossly necrotic and/or hemorrhagic, consistent with bowel infarction secondary to intussusception.
Both necrotic and viable polyps demonstrate similar architectural findings. There is arborization of the muscularis mucosa throughout the polyp. The branching is somewhat haphazard, giving rise to hollow triangles of muscularis mucosa that are filled with normal-appearing mucosal glands. Normal and hyperplastic small bowel mucosal glands are also arranged along the branching strands of muscularis mucosa. No dysplastic changes are identified.
