Summary
Aggressive B-cell lymphoma can present as anasarca, a rare and previously undescribed condition. Flow cytometry rapidly diagnoses this unusual lymphoma presentation, aiding in prompt patient management.
Area of Science:
- Oncology
- Hematology
- Immunophenotyping
Background:
- Anasarca, or generalized edema, is a complex clinical sign with diverse etiologies.
- Lymphoma, a malignancy of lymphocytes, typically presents with lymphadenopathy or systemic symptoms.
Observation:
- Two patients with anasarca were diagnosed with aggressive B-cell lymphoma without bulky disease.
- Diagnosis was achieved rapidly via flow cytometric analysis of pleural or peritoneal cells.
Findings:
- Flow cytometry identified specific cell surface immunophenotypes and cell cycle fractions consistent with lymphoma.
- This presentation of lymphoma is unusual and previously undescribed in medical literature.
Implications:
- Lymphoma should be considered in the differential diagnosis of patients presenting with anasarca.
- Flow cytometry offers a rapid and effective method for confirming lymphoma in such cases.
- This rare presentation may indicate a negative prognostic impact, necessitating early intervention.
