Summary
A rare placental tumor, known as ectopic liver, is described. This case involves an early five-week embryo, highlighting a rare umbilical cord alteration.
Area of Science:
- Reproductive biology
- Developmental biology
- Pathology
Background:
- Placental tumors are rare, with the first documented case of benign hepatic tissue in 1986.
- This lesion, initially termed placental benign hepatocellular adenoma, is now recognized as ectopic liver.
- Ectopic liver is a rare finding, with only 12 cases reported previously.
Observation:
- This study reports a novel case of ectopic liver.
- The ectopic liver was found in the umbilical cord.
- The affected embryo was only five weeks of gestational age.
Findings:
- This represents a rare instance of ectopic liver.
- It is an even rarer presentation of ectopic liver within the umbilical cord.
- The case occurred at a very early stage of embryonic development (five weeks).
Implications:
- This finding contributes to the understanding of rare placental and embryonic anomalies.
- Further research may elucidate the developmental origins of ectopic liver.
- Reporting such early cases is crucial for understanding the spectrum of congenital abnormalities.
