Summary
Testicular germ cell tumors are rare but common in young men. This case highlights a pure seminoma causing severe anemia through duodenal infiltration from a large retroperitoneal mass.
Area of Science:
- Oncology
- Gastroenterology
Background:
- Testicular germ cell tumors (GCTs) are the most common malignancy in young men, despite their rarity (1%).
- Gastrointestinal (GI) involvement by GCTs is uncommon (5%), typically manifesting as bowel obstruction or bleeding.
- Duodenal infiltration by GCTs is particularly rare, with limited data on its actual frequency.
Observation:
- A case of severe anemia due to GI bleeding is presented.
- The anemia was caused by a large retroperitoneal metastatic mass infiltrating the duodenum.
- This was the initial presentation of a pure testicular seminoma.
Findings:
- Pure seminoma, a subtype of GCT, can infiltrate the duodenum.
- Retroperitoneal lymph node metastasis can lead to duodenal invasion.
- Gastrointestinal bleeding and anemia can be the first signs of advanced testicular cancer.
Implications:
- This case underscores the importance of considering GCTs in young men presenting with unexplained GI bleeding and anemia.
- It highlights a rare but severe manifestation of pure seminoma.
- Further research may be needed to better define the incidence and mechanisms of duodenal infiltration by GCTs.
