McCune-Albright syndrome is an inherited disease characterized by the association of fibrous dystrophy of bone, café-au-lait skin spots and precocious puberty revealing endocrine hyperactivity. Genetically, this disease is due to a mutation of the Gs protein responsible for activation of adenylate cyclase with excessive production of cAMP. The particular morphology of café-au-lait spots should suggest early diagnosis. Its treatment depends on the endocrinopathy from which the patient suffers and the extent of the fibrous dysplasia. Bisphosphonates have proven their effectiveness on bone pain and the limitation of fibrous dysplasia. Surgery retains its place in complicated forms. We report a rare case of McCune-Albright syndrome complicated by a femur fracture in a 12-year-old girl and we discuss the clinical and paraclinical characteristics of this pathological entity.
McCune-Albright综合征是一种遗传性疾病,其特征为骨纤维营养不良、咖啡斑皮肤斑点和提示内分泌功能亢进的性早熟同时存在。从遗传学角度来看,该疾病是由于负责激活腺苷酸环化酶的Gs蛋白发生突变,导致环磷酸腺苷(cAMP)过度产生。咖啡斑的特殊形态应提示早期诊断。其治疗取决于患者所患的内分泌病以及纤维发育异常的程度。双膦酸盐已证实对骨痛和纤维发育异常的限制有效。手术在复杂病例中仍有其地位。我们报告了一例12岁女孩并发股骨骨折的罕见McCune-Albright综合征病例,并讨论了该病理实体的临床和辅助检查特征。
