A 42-year-old woman was admitted to our hospital because of easy fatigability in Jan. 1976. Laboratory examination revealed severe macrocytic anemia and slight lymphocytosis. She was diagnosed as having pure red cell aplasia (PRCA). She went into hematological remission 6 weeks following 40 mg/day treatment with prednisolone, but the anemia relapsed frequently when the dosage was lessened. She was then treated with 50 mg/day of cyclophosphamide, 50 mg/day of azathioprine, splenectomy, and methylprednisolone pulse therapy, but the recovery from anemia was temporary after each treatment. Since 1984, peripheral lymphocyte counts were 1∼30,000/μl, and reticulocyte counts were 0. She died of sepsis of Listeria in Sep. 1986.
Peripheral lymphocytes had large azurophilic granules and an immunophenotype of OKT3+8+11+Ia1+Leu7+.
