Malignant gonadal stromal tumors are rare. Retroperitoneal lymph node dissection improves outcomes, but advanced disease prognosis remains poor due to ineffective chemotherapy and radiotherapy.

Area of Science:

Oncology
Urology

Background:

Malignant gonadal stromal tumors are rare neoplasms.
Review of English and Japanese literature on 24 reported cases.

Observation:

A 34-year-old male presented with a painless left scrotal tumor.
Histologic examination confirmed a malignant gonadal stromal tumor after left high orchiectomy.
The patient remained disease-free for 41 months post-surgery.

Findings:

Retroperitoneal lymph node dissection (RPND) showed benefit in English literature cases (2/3 survivors with no evidence of disease).
Orchiectomy alone or with radiation had higher metastasis rates (5/6 patients).
Japanese literature cases treated with high orchiectomy and RPND also showed favorable outcomes (3/3 survivors).

Implications:

RPND appears beneficial for malignant gonadal stromal tumor treatment.
Advanced disease has a poor prognosis due to limited treatment efficacy.
Further research is needed to understand pathophysiology and develop effective therapies.
