We present a 6-year-old girl with skin hyperpigmentation, leukoplakia, and onychodystrophy, the classic mucocutaneous triad usually associated with dyskeratosis congenita. The patient also had premature graying of the hair, bone marrow failure, hepatitis, exudative retinopathy, osteopenia with multiple long bone fractures, and intracranial calcifications and brain cysts. Coats plus syndrome is a rare disease with a clinical and genetic overlap with dyskeratosis congenita. This disease is reviewed, with a focus on the pathogenesis of the genetic anomalies and its background as a telomere biology disorder.
我们报告一名6岁女孩,有皮肤色素沉着、黏膜白斑和甲营养不良,这是通常与先天性角化不良相关的典型黏膜皮肤三联征。该患者还出现了头发过早变白、骨髓衰竭、肝炎、渗出性视网膜病变、伴有多处长骨骨折的骨质减少以及颅内钙化和脑囊肿。科茨加综合征是一种罕见疾病,在临床和遗传方面与先天性角化不良有重叠。本文对该疾病进行了综述,重点关注基因异常的发病机制及其作为端粒生物学障碍的背景。
