Leydig cell tumors are rare in boys, causing precocious puberty due to increased sex steroids. Differentiating these tumors from congenital adrenal hyperplasia is crucial for appropriate treatment, often involving testis-sparing surgery.

Area of Science:

  • Pediatric Oncology
  • Endocrinology

Background:

  • Testicular tumors are rare in pediatric patients, with Leydig cell tumors accounting for approximately 1.5% of cases.
  • Leydig cell tumors in prepubertal children are typically benign but can present with significant hormonal disturbances.

Observation:

  • A 4.5-year-old boy presented with precocious puberty secondary to a Leydig cell tumor of the left testis.
  • The tumor was associated with elevated sex steroid production, leading to early pubertal development.

Findings:

  • Diagnostic challenges were encountered in this rare case.
  • Testis-sparing surgical removal was successfully performed.
  • Plasma 17-hydroxyprogesterone levels were key in distinguishing Leydig cell tumor from congenital adrenal hyperplasia in this patient.

Implications:

  • This case highlights the importance of considering Leydig cell tumors in the differential diagnosis of precocious puberty in boys.
  • Accurate hormonal assessment, particularly 17-hydroxyprogesterone levels, is vital for correct diagnosis.
  • Minimally invasive, testis-sparing approaches are feasible and desirable for benign pediatric testicular tumors.
