Summary
This case report details an extremely rare solitary extramedullary plasmacytoma of the testis in an 83-year-old man. The patient remained disease-free for over 14 months post-surgery, with no signs of multiple myeloma.
Area of Science:
- Oncology
- Pathology
- Urology
Background:
- Extramedullary plasmacytomas (EMPs) are rare plasma cell neoplasms.
- Testicular EMPs are exceptionally uncommon, particularly without concurrent multiple myeloma.
- This report focuses on a unique case of solitary testicular plasmacytoma.
Observation:
- An 83-year-old male presented with a solitary tumor of the left testis.
- The patient had no prior or concurrent diagnosis of multiple myeloma.
- Radical orchiectomy was performed for diagnosis and treatment.
Findings:
- Histologic examination revealed a solitary plasmacytoma of the testis.
- Immunoperoxidase studies demonstrated monoclonal IgG-lambda immunoglobulin.
- The tumor was classified as an extramedullary plasmacytoma.
Implications:
- Solitary testicular plasmacytomas can occur independently of multiple myeloma.
- This case highlights the importance of thorough diagnostic workup for testicular tumors.
- Long-term surveillance is crucial for patients with extramedullary plasmacytomas to monitor for recurrence or myeloma development.
