We describe an unusual case of B-cell neoplasm accompanied by pure red cell aplasia (PRCA) and myelofibrosis in a 67-year-old male presenting with severe anaemia. A few unclassified, myeloperoxidase-negative blastoid cells were seen on bone marrow aspiration, and erythroid cell hypoplasia and myelofibrosis on bone marrow biopsy. An autoimmune PRCA was suspected, as serum CH50, C3 and C4 levels were consistently low. Ciclosporin was effective in treating the anaemia, but anaemia returned when the drug was discontinued. Thirteen months later, the patient was admitted with pleural effusion and ascites that contained monoclonal CD19+ CD20+ immature blast cells with a complex karyotype, thought to be neoplastic B-cells. The unclassified blastoid cells seen earlier may therefore have been from the same origin. The patient deteriorated rapidly and died. Only one case of non-Hodgkin’s lymphoma with PRCA and myelofibrosis has been reported previously. We discuss the possibility that dysregulated T-cells induced by neoplastic B-cells may have given rise to concomitant PRCA and myelofibrosis
