Summary

This case study details a 15-month-old with ambiguous genitalia and a 46XX karyotype, presenting unique gonadal and reproductive tract findings. The patient exhibited an ovotestis and rudimentary internal structures, differing from typical true hermaphroditism.

Area of Science:

  • Reproductive Endocrinology
  • Genetics
  • Pediatric Endocrinology

Background:

  • Ambiguous genitalia in infants presents diagnostic challenges.
  • Understanding variations in sex development is crucial for accurate diagnosis and management.
  • True hermaphroditism, characterized by the presence of both ovarian and testicular tissue, is a rare disorder of sex development.

Observation:

  • A 15-month-old male infant presented with ambiguous external genitalia.
  • Genetic analysis revealed a 46XX karyotype.
  • Physical examination identified an ovotestis in the right labioscrotal fold and an absent left gonad.

Findings:

  • The patient possessed a rudimentary uterus and fallopian tubes.
  • A blind-ending vagina lined with squamous epithelium was observed.
  • These anatomical findings were compared to the spectrum of presentations in true hermaphroditism.

Implications:

  • This case highlights the diverse phenotypic expressions of 46XX disorders of sex development.
  • Accurate diagnosis requires integrating karyotype, gonadal, and anatomical findings.
  • Further research into the genetic and developmental pathways of sex determination is warranted.
