NEJM:先天性角化不良-案例报道

2017-04-13 xing.T MedSci原创

先天性角化不良是一种遗传性疾病,是由端粒长度变短所致,主要表现为骨髓衰竭、癌症、肺纤维化。外周血白细胞检测证实,该患者的端粒长度低于其年龄层次的第一个百分位数。

患者为一名52岁的男性,因咳嗽和呼吸困难2个月而就诊。该患者既往有全血细胞减少的病史,虽然以前进行过检查,包括骨髓活检,但并未找到任何病因性诊断。该患者的弟弟因再生障碍性贫血接受骨髓移植后死亡。

体检发现身材矮小,细花白的头发,牙齿脱落,指甲营养不良(图A),舌白斑(图B),网状的颈部色素减退(图C)。胸部计算机断层扫描显示肺下叶纤维化的特征性表现。指甲营养不良、黏膜白斑和皮肤病变临床怀疑为先天性角化不良。

该患者开始服用丹那唑,一种合成雄激素,可以延长端粒,并随后增加他的血小板、红细胞、白细胞计数。
