Is pure red cell aplasia (PRCA) a clonal disorder?
Pure red cell aplasia (PRCA) is an uncommon disorder, many cases lacking a well defined aetiology. This report describes three cases of PRCA (two idiopathic and one associated with B-CLL) who were investigated to assess the possibility of their PRCA being associated with a clonal proliferation of T-lymphocytes. The results show that one patient had evidence of T-cell receptor (TCR) gamma chain rearrangement, and the other had a TCR delta chain rearrangement. These two cases raise the possibility of PRCA being associated with a clonal proliferation of T-cells and further studies are warranted.
