โฆ Synopsis
A patient with pure red cell aplasia and expansion of the peripheral blood natural killer (NK) cell population is described. Despite normal absolute and differential leukocyte counts, NK cells were increased at diagnosis and at relapse. Furthermore, these cells were not morphologically recognizable on the peripheral blood smear examination. A favorable clinical response to glucocorticoid therapy was accompanied by a decrease in NK cells.

Several investigators have reported patients with acute pure red cell aplasia (PRCA) caused by anticonvulsants, antibiotics, or antithyroid agents. Allopurinol is known to be a causative agent of aplastic anemia, but there have been few reports of acute PRCA induced by allopurinol. We describe here
