Summary
This case report details an extremely rare IgD-paraproteinemia immunocytoma. The aggressive cancer showed poor response to treatment, highlighting IgD-paraproteinemia
Area of Science:
- Hematology
- Oncology
- Immunology
Background:
- Immunocytoma is a rare B-cell malignancy.
- IgD paraproteinemia is an uncommon immunoglobulin abnormality.
- This study presents a unique case of immunocytoma associated with IgD paraproteinemia.
Observation:
- A 65-year-old male presented with infiltrative immunocytoma of the throat and sinuses.
- Diagnosis was confirmed via biopsy and serum immunoelectrophoresis.
- The patient exhibited resistance to chemotherapy and radiotherapy.
Findings:
- The immunocytoma transformed into immunoblastic sarcoma with acute plasma-cell leukemia.
- Renal failure occurred due to kidney infiltration, leading to death 11 months post-diagnosis.
- IgD paraproteinemia correlated with poor prognosis and treatment response.
Implications:
- IgD paraproteinemia may indicate a poor prognosis in immunocytoma.
- Serum electrophoresis and immunoelectrophoresis are valuable for monitoring tumor recurrence.
- This case underscores the importance of recognizing rare paraprotein subtypes in hematologic malignancies.
