Abstract:
Seminomas rarely metastasize to the gastrointestinal tract. In general, these lesions metastasize to the lungs or retroperitoneal lymph nodes. A 34-year-old Japanese man who had undergone orchiectomy for seminoma two years earlier experienced shortness of breath and tarry stools. The patient presented at our hospital and was diagnosed with metastatic seminoma to the third portion of the duodenum on double balloon endoscopy. He was effectively treated with chemotherapy and continues to progress well, with no episodes of recurrence.
Insights
Seminomas rarely spread to the digestive system. This case report details a rare instance of metastatic seminoma in the duodenum, successfully treated with chemotherapy.
Area of Science:
- Oncology
- Gastroenterology
Background:
- Seminomas typically metastasize to lungs or retroperitoneal lymph nodes.
- Gastrointestinal metastasis from seminoma is exceptionally rare.
Observation:
- A 34-year-old man with a history of orchiectomy for seminoma presented with dyspnea and melena.
- Diagnostic endoscopy revealed metastatic seminoma in the third portion of the duodenum.
Findings:
- The patient received chemotherapy for metastatic duodenal seminoma.
- The treatment resulted in a positive clinical outcome with no recurrence.
Implications:
- This case highlights the importance of considering rare metastatic sites in oncology.
- Effective chemotherapy management is crucial for patients with advanced seminoma, even with unusual presentations.
