|October 1, 1980
Summary
This case report details a rare instance of Down syndrome (47, XX, +21) in a girl with unusual genital abnormalities, including labio-scrotal fusion and clitoral hypertrophy. The findings highlight a unique combination of genetic and anatomical features.
Area of Science:
- Genetics
- Developmental Biology
- Reproductive Medicine
Background:
- Down syndrome (47, XX, +21) is a genetic disorder typically associated with specific physical characteristics.
- Genital abnormalities can occur in individuals with chromosomal abnormalities, but specific combinations are rare.
Observation:
- A patient with Down syndrome presented with labio-scrotal fusion and clitoral hypertrophy.
- Anatomopathological examination revealed absent gonads, rudimentary Fallopian tubes, and the presence of Botal's orifice.
Findings:
- This case represents the first reported association of Down syndrome with this specific constellation of genital anomalies.
- The combination of labio-scrotal fusion, clitoral hypertrophy, gonadal agenesis, and Botal's orifice in Down syndrome is unprecedented.
Implications:
- This case expands the known spectrum of phenotypic variability in Down syndrome.
- Further research may elucidate potential shared developmental pathways or coincidental occurrences of these conditions.
- Understanding such rare associations is crucial for comprehensive patient care and genetic counseling.
