Summary
This case report details chronic neutrophilic leukemia co-occurring with multiple myeloma. Effective treatment with melphalan and prednisone led to patient improvement, though some symptoms persisted.
Area of Science:
- Hematology
- Oncology
Background:
- Chronic neutrophilic leukemia (CNL) is a rare myeloproliferative neoplasm.
- Multiple myeloma is a malignancy of plasma cells.
Observation:
- A patient presented with symptoms including bruising, weight loss, mature neutrophilic leukocytosis, hepatosplenomegaly, and a high monoclonal IgG lambda level (57.3 g/L).
- Bone marrow examination revealed myeloid hyperplasia and immature plasma cells.
Findings:
- The patient was diagnosed with chronic neutrophilic leukemia associated with multiple myeloma.
- Treatment with melphalan and prednisone for one year resulted in clinical improvement, reduced monoclonal IgG levels to 25.8 g/L, and persistent neutrophilic leukocytosis and splenomegaly.
Implications:
- This case highlights the importance of considering co-existing hematologic malignancies.
- Combined treatment approaches may be effective for managing complex cases of chronic neutrophilic leukemia and multiple myeloma.
