SIGMOID COLON, RESECTION: | |||
- BOWEL WALL ISCHEMIA WITH PERFORATION, SEROSITIS, AND FOCAL POORLY FORMED | |||
PSEUDOMEMBRANES. | |||
- MILD ATHEROSCLEROSIS. | |||
- DIVERTICULAR DISEASE. | |||
- TWO LYMPH NODES NEGATIVE FOR MALIGNANCY ( 0 POSITIVE / 2 ). | |||
- PLEASE SEE COMMENT. | |||
COMMENT: | |||
The sections show the changes of acute and chronic ischemic colitis (submucosal fibrosis, | |||
lamina propria hyalinization, focal crypt drop-out, decreased goblet cells, pigmented | |||
macrophages in the lamina propria, intraepithelial neutrophils). | |||
No granulomas are identified. The inflammation is largely associated with | |||
the necrosis/ischemic changes and favoured to be reactive. | |||
The poorly formed pseudomembranes are associated with mural ischemic changes; they do not | |||
specifically suggest an infectious etiology in this context. | |||
The blood vessels do not show a vasculitis. However, focal neutrophilic perivascular | |||
inflammation is seen; this is probably a reactive process. No vascular thrombi are | |||
identified. | |||
The findings are compatible with perforation secondary to a foreign body in the setting of | |||
chronic ischemia. | |||
