Quando il dolore osseo viene… dal sangue

The paper describes the case of an 8-year-old Moroccan girl who presented with recurrent multi-focal bone pains associated with negative flogosis indexes and standard radiological exams. The magnetic resonance exam of her thighbones showed a multi-focal inflammation; bone biopsy showed that the inflammation was aseptic and secondary to an osteonecrosis caused by vaso-occlusive crisis. After the haemoglobin electrophoresis performed in consideration of the persistent evidence of a mild microcytic anaemia with anisocytosis, the diagnosis was of thalasso-drepanocytosis. Thalasso-drepanocytosis is one of the sickle cell syndromes characterised by heterozygosis associated with thalassemic haemoglobinopathy. It can be clinically similar to homozygote drepanocytosis and therefore it needs the same therapeutic approach and follow-up. The case highlights the importance of thinking about sickle cell crisis, also in absence of important anaemization, when foreign patients coming from world’s endemic areas for thalassemic haemoglobinopathy present with recurrent bone pains.
