Fracture obstétricale bilatérale des jambes : complication très rare mais possible d´une présentation de siège

5q syndrome - is a unique paradigm of myelodysplastic syndrome (MDS) characterized by the correlation between cytology and cytogenetics and the low risk of clinical progression. It is a category apart in myelodysplastic syndromes (MDS) because of hematological peculiarities, the pathophysiology that remains unknown, and the refractoriness of the anemia with which it is associated. It is a pathology that affects the female sex with predilection. The prognosis of the disease remains good and the risk of malignant transformation into acute leukemia does not exceed 15%. In this work, we report a typical case of SMD with deletion of the long arm of chromosome 5 in order to describe the observation of this particular entity diagnosed in our formation, rare in our Moroccan context and that we must know how to evoke in front of a refractory anemia most often isolated.
