Background:
T-cell large granular lymphocytic leukemia (T-LGLL) is a rare type of aplastic anemia with diverse clinical manifestations. Concomitant diseases are often present at the first manifestation. We describe the treatment of a patient with CD57-negative γδT-LGLL with pure red cell aplasia (PRCA).
Case Summary:
A 34-year-old woman with a 20-year history of anemia visited our hospital owing to severe dizziness and was admitted. Her condition was diagnosed as CD57-negative γδT-LGLL with PRCA through bone marrow cytology, bone marrow pathology, bone marrow flow cytometry, bone marrow multiplex polymerase chain reaction combined with fluorescent fragment analysis, and other tests. Treatment with prednisone, methotrexate, and subcutaneous erythropoietin did not significantly change her hemoglobin level. After treatment with oral cyclophosphamide for 3 mo, her hemoglobin level increased to approximately 100 g/L. After 5 mo of treatment, the patient could perform activities of daily living independently.
Conclusion:
The treatment of CD57-negative γδT-LGLL with PRCA with cyclophosphamide helps to improve prognosis.
