Summary
This case report details three patients with primary mediastinal seminoma, a rare germ cell tumor. All patients survived following surgical resection and adjuvant therapies, including chemotherapy and radiotherapy.
Area of Science:
- Oncology
- Thoracic Surgery
- Germ Cell Tumors
Background:
- Primary mediastinal seminoma is a rare malignant germ cell tumor.
- Diagnosis can be challenging, often preoperatively mistaken for thymoma.
Observation:
- Three patients with primary mediastinal seminoma were analyzed.
- Two patients were asymptomatic; one presented with thoracic pain.
- Preoperative diagnosis was thymoma in all cases, with seminoma suspected in one.
Findings:
- Surgical tumor resection was performed via median sternotomy or thoracotomy.
- Primary gonadal seminoma was excluded through urological and ultrasound examinations.
- All patients remain alive post-treatment, with follow-up durations of 120, 8, and 84 months.
Implications:
- Successful management of primary mediastinal seminoma is achievable with multimodal therapy.
- Adjuvant chemotherapy regimens included cisplatin, etoposide, ifosfamide, bleomycin, and velbe.
- Radiotherapy was also utilized as an adjuvant treatment modality.
