Red cells collected and washed apparently under identical conditions may not yield a deposit of the same density. A 5 per cent, or 3 per cent, suspension made from the deposit will consequently differ fronn day to day. The minimum haemolytic dose of the complement obtained therefore is not comparable on different days. Besides, with a suspension thicker than usual an M. H. D. is obtained which ...

although the most common hematological disturbance in thymoma is pure red cell aplasia, pancytopenia is a very rare paraneoplastic syndrome in this disorder. we only found one case in literature reviews. we report a 36 year old female with an anterior mediastinal mass and severe pancytopenia. with a mediastinotomy incision, biopsy of the tumor was obtained. the report of the pathologist was thy...

Pyoderma gangrenosum is an inflammatory condition of the skin commonly associated with inflammatory bowel disease and rheumatoid arthritis, but also associated with various hematological malignancies. We describe its association with pure red cell aplasia in a four year old boy who presented with progressive skin lesions, fever and pallor, and improved with corticosteroid therapy.

Pure red cell aplasia (PRCA) is a bone marrow failure disorder. Several drugs have been reported as having induced PRCA, but lenalidomide-induced PRCA is rarely reported. Here we present a patient with myelodysplastic syndrome (MDS) who developed PRCA after treatment with lenalidomide. A 47-year-old male presented with a history of weakness with effort intolerance for 5 months. Examination show...
