Leydig cell hyperplasia (LCH) is uncommon in children, often presenting with precocious puberty. This case highlights incidental ultrasound discovery of LCH in a young boy, emphasizing conservative surgical management and follow-up.

Area of Science:

  • Pediatric Endocrinology
  • Urologic Pathology

Background:

  • Leydig cell hyperplasia (LCH) is a rare testicular condition in pediatric patients.
  • Clinical presentation typically involves signs of precocious puberty or gynecomastia, with lesions rarely being palpable.

Observation:

  • A 9-year-old boy presented with painless testicular enlargement.
  • Scrotal ultrasound revealed an incidental 12 mm echogenic mass with hypoechoic areas in the lower pole of the testis.
  • Tumor markers and hormonal assessments were within normal limits.

Findings:

  • Histological examination confirmed Leydig cell hyperplasia (LCH) measuring 5 mm.
  • Surgical exploration revealed a macroscopically normal testis, with the lesion identified and enucleated after opening the tunica albuginea.
  • The patient experienced an uneventful postoperative course with normal follow-up for two years.

Implications:

  • This case underscores the utility of scrotal ultrasound in incidentally detecting testicular LCH in children.
  • Endocrine assessment, particularly for luteinizing hormone (LH) levels, is crucial.
  • Conservative surgical approaches like enucleation-resection are recommended for managing testicular LCH.
