This case report describes a unique case of acquired elliptocytosis presumably related to MDS, with a high percentage of ring sideroblasts.
While the causal factor(s) leading to acquisition of elliptocytosis in cases of MDS have not been definitively identified, several cases have noted decreased levels of human erythroid protein 4.1 in association with del(20q) [9-11].
A correlation between deletions on the long arm of chromosome 20 and acquisition of elliptocytosis in MDS has emerged since the first patient with acquired elliptocytosis in what we now call MDS was reported by Hartz et al.
