Primary plasmacytoma of lymph nodes. A case report
Acta Haematologica
|January 1, 1979
Summary
Primary plasmacytomas of lymph nodes are exceptionally rare, often mistaken for metastases. This case highlights a rare instance of primary lymph node plasmacytoma without bone marrow involvement, offering insights into this uncommon malignancy.
Area of Science:
- Hematology
- Oncology
- Pathology
Background:
- Plasmacytomas typically arise as secondary metastases from multiple myeloma or primary sites in the upper respiratory tract.
- Primary plasmacytomas originating within lymph nodes are exceedingly uncommon in medical literature.
Observation:
- A rare case involving primary plasmacytoma affecting mediastinal, cervical, and para-aortic lymph nodes is presented.
- The patient exhibited significant Bence Jones proteinuria (8 g/24 h).
- Initial and repeated bone marrow examinations did not reveal any signs of myeloma or plasmacytoma involvement.
Findings:
- Despite extensive lymph node involvement, the bone marrow remained unaffected throughout the patient's clinical course.
- The patient succumbed to the disease 17 months after symptom onset, with the bone marrow consistently negative for plasmacytoma.
Implications:
- This case underscores the possibility of primary lymph node plasmacytoma presenting without concurrent bone marrow disease.
- Further research is warranted to understand the distinct biology and clinical behavior of primary lymph node plasmacytomas.
- Highlights the importance of thorough investigation in cases of unexplained lymphadenopathy and proteinuria, even with normal bone marrow findings.
