Abstract:
A case of meconial disease not associated with mucoviscidosis registered in 0.08% of perinatal autopsies is described in a premature girl who died 46 hours after her birth. Productive exudative meconial peritonitis that had developed due to intestinal wall perforation caused by meconium plug pressure was detected on the section. Microscopically, there were abundant squamous epithelial scales in the fibrinous exudate and commissures, whereas in the submucosal layer of the intestinal wall there were productive aseptic meconial granulomas whose components are squamous epithelial scales in addition to cellular elements. Searches for granulomas are made concurrently with examination of great quantities of histologic sections, but their detection is valuable for differential diagnosis of newborn ulcerous enterocolitis.
Insights
A rare case of meconial disease, unrelated to cystic fibrosis, occurred in a premature infant. The condition involved intestinal perforation and peritonitis, highlighting the importance of identifying meconial granulomas in neonatal pathology.
Area of Science:
- Neonatal Pathology
- Gastrointestinal Diseases
Context:
- Presents a rare case of meconial disease in a premature infant, distinct from cystic fibrosis.
- Meconial disease is found in 0.08% of perinatal autopsies.
Purpose:
- To describe a case of meconial disease leading to intestinal perforation and peritonitis.
- To highlight the diagnostic value of identifying meconial granulomas.
Summary:
- A premature infant experienced fatal meconial peritonitis due to intestinal perforation caused by meconium plug pressure.
- Histological examination revealed squamous epithelial scales and aseptic meconial granulomas in the intestinal wall.
Impact:
- Emphasizes the significance of recognizing meconial granulomas for the differential diagnosis of neonatal enterocolitis.
- Contributes to understanding rare causes of neonatal intestinal complications.
