[>Femoral bone infarction revealing compound heterozygous SC sickle cell disease in a Moroccan patient]. / Infarctus de l´os fémoral révélant une drépanocytose composite SC chez un patient marocain.

Double heterozygosity SC is a major sickle cell syndrome. Its course may be marked by severe or irreversible complications, such as bone infarction. We here report the case of a 17-year-old patient presenting with compound heterozygous SC sickle cell disease following severe knee pain (gonalgia) in order to highlight the risk of delayed diagnosis as well as the need for prevention policies guiding early screening, thus improving patients' management and prognosis.
