Abstract:
Germ cell tumors (GCT) are rare, frequently diagnosed in men aged 20-34 years old, and have a 95% 5-year relative survival rate. Metastasis from GCT has predictable spread to retroperitoneal lymph nodes. However, in cases of scrotal violation or tumor spillage, lymphatic drainage can be altered. Beyond the retroperitoneum, the most reported extra-nodal sites of metastases include the liver, lung, brain, and bone. Here we report a case of an unusual site of metastasis to the corpora cavernosa, as well as the complex reconstruction required to preserve sexual function.
Insights
Germ cell tumors (GCT) rarely spread outside lymph nodes, but can metastasize to unusual sites like the corpora cavernosa. This case highlights complex surgical reconstruction to maintain sexual function after GCT metastasis.
Area of Science:
- Oncology
- Urology
- Surgical Oncology
Background:
- Germ cell tumors (GCT) are the most common cancer in young men (20-34 years).
- GCT typically metastasizes to retroperitoneal lymph nodes with predictable lymphatic spread.
- Established extra-nodal metastatic sites include liver, lung, brain, and bone.
Observation:
- This report details a rare case of GCT metastasis to the corpora cavernosa.
- The patient experienced altered lymphatic drainage due to scrotal violation and tumor spillage.
- Unusual metastatic spread necessitates tailored surgical intervention.
Findings:
- The case demonstrates an atypical GCT metastatic pattern involving the corpora cavernosa.
- Complex surgical reconstruction was performed to address the unusual metastasis.
- Preservation of sexual function was a key surgical objective.
Implications:
- This case expands the understanding of GCT metastatic potential.
- Highlights the importance of considering unusual sites in advanced GCT.
- Underscores the role of reconstructive surgery in maintaining quality of life for GCT survivors.
