[Anatomical study of a human case of total celosomia]
Insights
This study details a rare case of total caelosomia in a 36-gestational-week human specimen. The infant presented with multiple severe congenital abnormalities, including ectocardia and cloacal exstrophy.
Area of Science:
- Developmental biology
- Teratology
- Human embryology
Background:
- Caelosomia, a rare congenital anomaly, involves the absence of anterior body wall structures.
- This case presents a complex spectrum of malformations requiring detailed classification.
Observation:
- A human specimen at 36 gestational weeks exhibited severe anterior abdominal wall defects (caelosomia).
- Abnormalities included superior (ectocardia, diaphragmatic hernia), middle (liver herniation, abnormal mesentery), and inferior (cloacal exstrophy) caelosomia.
- Additional findings were a lumbosacral meningocele and multicystic kidneys.
Findings:
- The specimen displayed a comprehensive set of developmental defects classifiable under total caelosomia.
- The combination of ectocardia, diaphragmatic hernia, abdominal organ herniation, cloacal exstrophy, meningocele, and renal dysplasia is exceptionally rare.
Implications:
- This case highlights the extreme phenotypic variability within the spectrum of caelosomia.
- Understanding such complex malformations is crucial for prenatal diagnosis and counseling.
- Further research into the genetic and environmental factors underlying total caelosomia is warranted.
Abstract:
The authors studied a human specimen delivered at 36 gestational weeks and presenting with a caelosomia. The various abnormalities could be classified as: superior caelosomia: ectocardia, diaphragmatic hernia; middle caelosomia: liver outside the abdominal cavity, mesenterium commune O, meso-hepato-cave; inferior caelosomia: cloacal extrophia. In addition to the forementioned abnormalities, a lumbosacral meningocele and multicystic kidneys were found. All these abnormalities are exceptionally found all together in one human specimen and this monster might be classified in the total caelosomia group.
