Plasma cell leukemia with IgA paraproteinemia and hyperviscosity

Area of Science:

• Hematology
• Oncology
• Internal Medicine

Background:

• Primary IgA plasma cell leukemia is an extremely rare plasma cell dyscrasia.
• Hyperviscosity syndrome is not a commonly reported complication of this condition.

Observation:

• A patient presented with primary IgA plasma cell leukemia, IgA lambda monoclonal gammopathy, elevated serum viscosity, and congestive heart failure.
• This constellation of symptoms is highly unusual for this specific leukemia subtype.

Findings:

• The patient's elevated serum viscosity and congestive heart failure were successfully managed.
• Treatment involved plasmapheresis to reduce blood viscosity and chemotherapy to target the leukemia.

Implications:

• This case highlights an unusual but serious complication of primary IgA plasma cell leukemia.
• It underscores the importance of monitoring for hyperviscosity and cardiac complications in affected patients.
• Effective management strategies combining plasmapheresis and chemotherapy can improve outcomes.
