The labioscrotal swellings (genital swellings or labioscrotal folds) are paired structures in the human embryo that represent the final stage of development of the caudal end of the external genitals before sexual differentiation. In both males and females, the two swellings merge:
- In the female, they become the posterior labial commissure. The sides of the genital tubercle grow backward as the genital swellings, which ultimately form the labia majora; the tubercle itself becomes the mons pubis. In contrast, the labia minora are formed by the urogenital folds.[1]
- In the male, they become the scrotum.

Reproductive system
development |
| Primarily internal |
- Gonadal ridge → Indifferent gonad → Gonadal cord (Cortical cords, Testis cords)
- Pronephric duct/Wolffian duct/mesonephric duct + Müllerian duct/paramesonephric ducts (Vaginal plate)
- US → Prostate or Skene's gland

| Primarily external |
- LPM → Genital tubercle → Labioscrotal swelling → Scrotum or Labia majora
- LPM → Genital tubercle → Primordial phallus → Penis or Clitoris
- Peritoneum → Processus vaginalis or Canal of Nuck

- We present the extremely rare phenotype of an accessory scrotum with an associated lipoblastoma. There was a coexistence of midperineal and lateral types. To our knowledge, this phenotype has never been reported. The lipoblastoma, which arose in the perineum, divided the moving labioscrotal swelling
