[Carpal Extensor Tenosynovitis and Adult Sickle Cell Vaso-Occlusive Crisis].

If the acute and chronic osteo-articular complications of sickle cell anemia are well-known to the rheumatologist, certain forms including hand-foot syndrome are less so since they almost exclusively concern small children less than 4 years of age. We report here the observation of a hand-foot syndrome in a 36-year-old adult, homozygous sickle cell disease (SS), during a vaso-occlusive crisis, manifested by tenosynovitis of carpal extensors. After eliminating the other etiologies, notably infectious of palmar tenosynovitis, the vaso-occlusive origin will be confirmed by the rapidly favorable evolution of the clinical picture.
