Spontaneous remission in pure red cell aplasia associated with thymoma

A 57-year-old woman with thymoma-associated pure red cell aplasia (PRCA) manifested spontaneous recovery of erythropoiesis. Anemia recurred before the surgical removal of her thymoma, however, and the second anemic remission following surgery did not occur promptly. In this report, we describe a rare occurrence of spontaneous remission in PRCA.
