Case Report: Ovarian dysgerminoma mimicking a sex cord-stromal tumor with hyperandrogenism: diagnostic challenges and molecular insights
To report a rare case of ovarian dysgerminoma in an 8-year-old girl presenting with hyperandrogenism, highlighting diagnostic challenges and molecular findings, and their implications for clinical practice.
Key Findings:
The patient exhibited profound hyperandrogenism with elevated testosterone levels.
Histopathological examination revealed unusual architectural patterns in the dysgerminoma.
Immunohistochemistry confirmed the diagnosis with germ cell markers and syncytiotrophoblasts.
Molecular profiling showed KRAS and CDK4 amplifications.
Interpretation:
The case illustrates the diagnostic complexity of dysgerminomas that mimic sex cord-stromal tumors, emphasizing the critical need for an integrated diagnostic approach to avoid misdiagnosis.
Limitations:
The rarity of the case limits generalizability and may affect the applicability of findings to broader populations.
Absence of germline genetic testing due to lack of clinical indicators may limit understanding of potential hereditary factors.
Conclusion:
This case highlights the importance of combining clinical, histopathological, and molecular data to accurately diagnose and manage complex pediatric ovarian tumors.
