Summary
A retroperitoneal seminoma, a rare cancer, was diagnosed in a patient presenting with abdominal pain. Further testicular biopsies are crucial to rule out occult or burned-out primary tumors.
Area of Science:
- Oncology
- Urology
Background:
- Extragonadal germ cell tumors, particularly seminomas, are rare.
- Retroperitoneal masses can present with non-specific symptoms like abdominal pain.
Observation:
- A 44-year-old male presented with left-sided abdominal pain, a supraclavicular lymph node, and atrophic testes.
- Imaging revealed a large retroperitoneal mass.
- Biopsy confirmed seminoma, but primary testicular tumors were absent.
Findings:
- Diagnosis of extragonadal primary retroperitoneal seminoma was established.
- The patient responded favorably to cisplatin, bleomycin, and etoposide chemotherapy.
- Histological examination of testes is mandatory to differentiate from occult or burned-out primary testicular seminoma.
Implications:
- This case highlights the importance of considering extragonadal germ cell tumors.
- Definitive diagnosis requires thorough testicular evaluation.
- Chemotherapy regimens are effective for retroperitoneal seminomas.
