Summary
A burned-out testicular tumor presented as a retroperitoneal mass. Successful treatment involved chemotherapy and surgery, leading to no recurrence in this rare case.
Area of Science:
- Oncology
- Urology
Background:
- Testicular tumors can rarely present as 'burned-out' primary lesions with metastatic disease.
- Diagnosis can be challenging due to the absence of viable primary tumor cells.
Observation:
- A 29-year-old man presented with a left lower abdominal mass and testicular nodule.
- Imaging revealed a large retroperitoneal mass, suspected to be metastatic testicular cancer.
- Initial orchiectomy showed no viable tumor cells, only fibrotic changes.
Findings:
- Post-chemotherapy, the retroperitoneal mass was surgically removed and contained embryonal carcinoma, teratoma, and yolk sac tumor components.
- The patient achieved remission after combined treatment and remains recurrence-free.
Implications:
- This case highlights the importance of considering 'burned-out' testicular tumors in the differential diagnosis of retroperitoneal masses.
- Multimodal treatment including chemotherapy and surgery can be effective even with advanced metastatic disease from cryptic primary tumors.
