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.
