患者男,20岁.约5岁开始上胸部皮色加深伴指甲发育不良,后皮损渐扩展至头面部及躯干,近5年皮损发展较快,大部分指、趾甲萎缩,未曾诊治.4个月前因发热、咳嗽在当地医院诊断为“肺结核”,给予抗结核治疗3个月,病情无改善.于2005年9月6日和9月30日分别行骨髓细胞学检查,结果为巨核细胞减少、功能差和骨髓造血组织功能极度低下.因病情持续加重于10月5日入住我院.诊断:①间质性肺炎;②再生障碍性贫血.给予抗感染对症治疗.因全身皮肤色素沉着请我科会诊.父母非近亲结婚,否认家族中有类似疾病患者. 相似文献

先天性角化不良(dyskeratosis congenita,DC)是一种以皮肤萎缩、网状色素沉着、色素减退,以及甲营养不良、黏膜白斑为特征的先天性综合征,伴随多系统外胚叶和一些中胚叶的变化。临床罕见,现将我院1例报告如下。l临床资料 患者男,19岁。因“甲变形9年余,面部、躯干、四肢皮肤异色7年余”来院就诊。9年前无明显诱因部分指甲板出现萎缩、变尖、弯曲并脱落。1年内其它指甲板和趾甲板也开始脱落。2年后双前臂出现褐灰色色素沉着,无自觉症状,呈网状分布,后皮损逐渐扩大,蔓延至面部、颈部及双小腿,皮损无日晒后加重现象。患者无牙龈增生、畏光、流泪及吞咽、排尿困难等不适。 相似文献

先天性角化不良(DC)是一种罕见的遗传性皮肤病,其临床特征为皮肤色素沉着、甲营养不良、黏膜白斑和骨髓增生障碍。分子遗传学研究显示,本病存在遗传异质性,其遗传方式为X连锁隐性遗传、常染色体显性遗传和常染色体隐性遗传3种,目前发现前2种遗传类型的致病基因为DKC1和TERC。该病治疗比较棘手,目前尚无根治方法。 相似文献

先天性角化不良是一种少见的先天遗传性皮肤病,其临床三联征包括:甲板营养不良,口腔或阴道等可出现白斑,皮肤异色症样的色素沉着。先天性角化不良是与编码角化不良蛋白基因、编码端粒酶的RNA组份基因、编码端粒酶的逆转录酶基因突变及其他未确认的致病基因突变引起的基因病,其遗传方式有:X-性联隐性遗传、常染色体显性遗传及常染色体隐性遗传。治疗上还缺乏有效的治疗方法。文中从先天性角化不良的发病机制、突变类型、临床表型以及治疗方面综述先天性角化不良的研究进展。 相似文献

Pulmonary arteriovenous malformations (PAVMs) are rare lesions known to cause cyanosis due to abnormal communication between the pulmonary arteries and veins. They are commonly seen in association with hereditary hemorrhagic telangiectasia, congenital heart disease, hepatopulmonary syndrome, and portopulmonary shunting, but rarely in patients with dyskeratosis congenita (DC). We describe a patient previously diagnosed with DC confirmed to have microscopic PAVMs after bone marrow transplantation and discuss possible pathogenic mechanisms. 相似文献

Abstract: A case of dyskeratosis congenita (DC) of an 11-year-old male is reported. He presented with the characteristic clinical triad of reticular pigmentation of the skin, dystrophic nails and oral lesions, and up to the present he had not developed hematological compromise. Oral lesions consisted of extensive tongue erosions and keratosis, and exuberant gingivitis associated. Appropriate periodontal treatment was performed with discrete improvement only. We emphasize that severe gingival inflammation, although infrequent, may represent an alteration specific to DC and therefore should be considered as an additional sign of this syndrome. 相似文献

Hoyeraal–Hreidarsson syndrome is a rare telomere biology disorder that is recognized as a severe variant of dyskeratosis congenita. We present a Libyan boy with hematologic and neurologic abnormalities with typical dermatologic manifestations of dyskeratosis congenita. Death usually occurs before the age of 4 years as a result of pancytopenia or malignant transformation of mucocutaneous lesions. The boy presented survived longer than 5 years. Early recognition and appropriate genetic counseling are crucial because of the high mortality of this genetic disorder. 相似文献
