Summary

Neoplastic processes, including ovarian and testicular tumors, are rare causes of precocious puberty. Ruling out cancer is crucial for accurate diagnosis and treatment of precocious puberty in children.

Area of Science:

  • Pediatric Endocrinology
  • Oncology
  • Neuroendocrinology

Background:

  • Neoplasms are rare but significant causes of precocious puberty in both males and females.
  • Identifying neoplastic causes is critical due to therapeutic and prognostic implications.
  • Specific tumors like granulosa-cell and Leydig-cell tumors are common gonadal culprits, while adrenal tumors cause various endocrine syndromes.

Purpose of the Study:

  • To review the role of tumors in causing precocious puberty.
  • To differentiate between true precocious puberty and pseudopuberty induced by neoplasms.
  • To highlight the importance of oncological screening in precocious puberty evaluations.

Main Methods:

  • Literature review of studies on tumors associated with precocious puberty.
  • Analysis of tumor types, their hormonal effects, and clinical presentations.
  • Categorization of tumors based on their origin (gonadal, adrenal, cerebral) and effect.

Main Results:

  • Granulosa-cell tumors (ovary) and Leydig-cell tumors (testis) are frequent causes of precocious pseudopuberty.
  • Adrenal tumors commonly present with virilization or hypercortisolism, but feminizing types exist.
  • Cerebral tumors like hypothalamic hamartoma, hypothalamochiasmatic glioma, and craniopharyngioma can cause true precocious puberty, with hamartomas increasingly recognized due to advanced imaging.

Conclusions:

  • Tumors must be considered in the differential diagnosis of all cases of precocious puberty.
  • Distinguishing between true precocious puberty and pseudopuberty is essential for appropriate management.
  • Improved diagnostic imaging has increased the identification of cerebral lesions like hypothalamic hamartomas causing precocious puberty.
