Created page with "==Meconium peritonitis with remote perforation== ===Microscopic description=== The sections show small bowel with bowel wall necrosis, focal calcification, perforation and extens..."

New page

==Meconium peritonitis with remote perforation==
===Microscopic description===
The sections show small bowel with bowel wall necrosis, focal calcification, perforation and extensive serosal, predominantly lymphoplasmcytic, inflammation. There is meconium within the bowel wall and on the serosal surface. Ganglion cells are present in normal numbers and have a normal distribution. The mucosa does not have crypt enlargement, or intracellular or extracellular accumulation of mucus.

===Final diagnosis===
Small bowel, ileum, resection
- Meconium peritonitis.
- Remote perforation, see comment.

===Comment===
The findings are consistent with a remote vascular injury. There are no histomorphologic findings to suggest Hirschsprung disease or cystic fibrosis.
