Summary

A 7-year-old boy with precocious puberty was diagnosed with a Leydig cell tumor. This rare testicular tumor showed malignancy after initial removal, necessitating further treatment.

Area of Science:

  • Pediatric Endocrinology
  • Reproductive Endocrinology
  • Oncology

Background:

  • Precocious puberty in children can be caused by various factors, including hormone-secreting tumors.
  • Leydig cell tumors are the most common type of sex cord-stromal tumors of the testis, typically presenting in adults.

Observation:

  • A 7-year-old boy presented with bilateral testicular swelling, advanced penile development, and a bone age of 13 years.
  • Hormonal evaluation revealed elevated testosterone, estradiol, dehydroepiandrosterandrosterone sulfate (DHEA-S), and 17-ketosteroids, with pubertal responses to GnRH testing.
  • Testicular biopsy confirmed Leydig cell tumor with Reinke crystals.

Findings:

  • Enucleation of the tumor revealed signs of necrosis and malignancy.
  • Leydig cell tumors, while rare in children, can exhibit malignant characteristics.

Implications:

  • This case highlights the importance of considering testicular tumors in the differential diagnosis of precocious puberty in pediatric patients.
  • The malignancy identified post-enucleation suggests a need for aggressive management, with orchiectomy being the recommended next step.
  • Current evidence indicates limited efficacy of chemotherapy and radiotherapy for Leydig cell tumors, underscoring the role of surgical intervention.
