The sections show rectal mucosa, submucosa and a small amount of muscularis propria. The mucosa shows fibromuscular hyperplasia with thickening of the muscularis mucosae and mild lamina propria fibrosis. The submucosa is edematous. The small amount of muscularis propria is unremarkable. The epithelium matures normally to the surface. No significant nuclear atypia is identified. | The sections show rectal mucosa, submucosa and a small amount of muscularis propria.

RECTAL MUCOSA, DELORME PROCEDURE: | |||
- SUPERFICIAL RECTAL WALL WITH REACTIVE CHANGES, ISCHEMIC CHANGES AND FIBROMUSCULAR | |||
HYPERPLASIA, SEE COMMENT. | |||
- NEGATIVE FOR MALIGNANCY. | |||
COMMENT: | |||
The changes are compatible with prolapse (fibromuscular hyperplasia) and suggestive of | |||
concurrent ischemia (see microscopic). | |||
The mucosal reactive changes are marked. No definite dysplasia is identified; however, it | |||
is difficult to completely exclude. Follow-up is recommended. | |||

====Micro==== | |||
The sections show superficial rectal wall with ischemic changes (focal cryptitis, marked | |||
reactive epithelial changes, erosions, capillary congestion, goblet cell paucitity, | |||
epithelium with attenuated cytoplasm) and changes compatible with prolapse (fibromuscular | |||
hyperplasia). | |||
