BACKGROUND: While standard blood tests are often sufficient for an anaemia workup, sometimes more invasive diagnostic testing is required to exclude rare conditions.
CASE PRESENTATION: A man in his forties contacted his general practitioner because of increasing functional dyspnoea. He had completed a course of dicloxacillin a few months previously for a skin abscess on his abdomen. Bloodwork revealed severe anaemia (haemoglobin 5.4 g/dL), which required transfusion. Subsequent testing excluded iron and vitamin deficiency anaemia, haemolysis and malignancy. Initial bone marrow biopsy was of suboptimal quality. However, repeat tissue sample supported a diagnosis of pure red cell aplasia. The patient improved with ciclosporin treatment, which was gradually tapered.
INTERPRETATION: Pure red cell aplasia should be considered in patients with new onset isolated anaemia with severe reticulocytopenia. Diagnosis depends on obtaining representative tissue from bone marrow biopsy. It is difficult to conclude for this patient whether the aetiology of his pure red cell aplasia was idiopathic or secondary to recent dicloxacillin use.
