106例性别发育异常患儿性腺病理学特征及其临床意义的初步探讨

目的总结分析性发育异常(disorders of sex cdevelopmemt,DSD)患儿性腺的病理学特点及其临床意义。方法收集2010年8月至2018年1月间于浙江大学医学院附属儿童医院就诊并获取性腺病理学检查结果的DSD患儿临床资料,同时根据染色体结果分成性染色体DSD组、46,XX DSD组、46,XY DSD组共3组进行对比分析。结果共有106例DSD患儿获得性腺病理检查结果,肿瘤发生率为1. 8%。3组间EMS评分无统计学差异。性染色体DSD组21例,其中卵睾型DSD 10例(47.6%)、原始性腺7例(33.3%)、发育不良卵巢1例(4.8%)、发育不良睾丸3例(14.3%)。46,XX DSD组25例,其中卵睾型DSD 11例(44%)、原始性腺3例(12%)、发育不良卵巢9例(36%)、发育不良睾丸2例(8%)。46,XY DSD组60例,其中卵睾DSD 2例(3.3%)、原始性腺7例(11.7%)、发育不良卵巢5例(8.3%)、发育不良睾丸44例(73.3%)、性腺母细胞瘤2例(3.3%)。不同DSD染色体分型中各种病理类型的构成比存在统计学差异(P0.05)。结论对于诊断结果尚不明确、需要接受性腺病理检查的DSD患儿,EMS得分及性腺病理结果与染色体核型不存在较为明显的对应关系。性腺病理检查仍是DSD诊断及治疗的重要评估手段,这对DSD患儿的个体化处理具有重要意义。此外,性腺发生恶变的机率较小。     

卵睾型性发育异常单中心临床诊治分析

目的 总结卵睾型性发育异常的临床特点及诊治经验.方法 回顾性分析1993年1月至2015年12月就诊于医院并通过病理确诊卵睾型性发育异常的32例患儿临床资料和随访资料.社会性别:男30例,女2例.12.5％呈女性外貌,生殖器类别模糊,阴蒂1～3 cm,小阴唇发育差,有乳房发育;87.5％呈男性外貌,阴茎发育极差,重度下弯,尿道开口异常(位于阴囊处或会阴部),阴囊不同程度女性化,外形近阴唇貌,其中46.9％(15/32)伴有隐睾.染色体核型分析:46,XX卵睾型DSD 11例;46,XY卵睾型DSD 1例;性染色体异常DSD中的卵睾型性发育异常20例(嵌合性46,XY/46,XX6例;混合型14例).结果 11例行泌尿生殖系彩超和排泄性尿道阴道造影,二者结合检出率为100％(11/11).5例行SYR基因筛查,1例45,X卵睾型DSD及1例45,X/46,XY卵睾型DSD为SYR阳性,1例45,X/46,XY SYR基因为阴性,余2例46,XX卵睾型DSD中,50％SYR基因为阴性.64个性腺中16个卵睾,25个睾丸,23个卵巢.性腺畸形:双侧型5例,单侧型6例,片侧型21例.30例按男性抚养者均完成阴茎矫直术和尿道重建术.对29例患儿进行8个月～9年的随访,其中3例术后反复发生尿瘘,多次行尿瘘修补术,阴茎及睾丸发育极差,生活质量差;4例术后尿道开口位于冠状沟部或阴茎体部,排尿可;3例进入青春期后有乳房发育;2例阴茎、睾丸发育稍差;余阴茎形态可,长2.5～4.0 cm,睾丸测值较同龄人稍小.2例按女性抚养者均完成阴蒂矫形术,均获得满意的外观,1例处于青春期发育阶段,另1例予雌激素替代治疗后获得青春期发育,外阴形态可,有乳房发育.结论 早期诊断,确诊后是否立刻性别选择行手术治疗仍有争议,我们认为应将患儿的心理性别、社会性别作为参考的首要标准结合激素水平评估、优势性腺评估最后选择性腺切除或重建手术并辅以激素治疗.对于维持患儿正常的性生理、性心理及社会生活具有重要的意义.     

卵睾型性发育异常的临床特征分析

儿童真两性畸形的诊断与外科处理探讨

目的探讨儿童真两性畸形的诊断与外科处理方法。方法回顾性分析2004年至2007年本院收治的9例儿童真两性畸形患儿病例资料。结果社会性别：男4例，女5例。染色体组型：46XX4例，46XY3例，45X01例，46XX／XY1例。性腺畸形：双侧型4例，单侧型2例，片侧型3例。4例选定作男性抚育者，于腹腔镜下切除卵巢组织及子宫附件，行隐睾下降固定，同期或二期行尿道成形术；5例选定作女性抚育者，于腹腔镜下切除睾丸组织或卵睾，同期行阴蒂成形术。所有患儿均无明显术后并发症，效果良好。结论早期诊断、早期治疗及综合判定，做出合理盼陛别选择对于儿童真两性畸形的诊治意义重大；外科处理应选择适宜的手术方式；腹腔镜在诊断与外科处理中可替代剖腹探查。     

混合性性腺发育不良的临床特点与误诊分析

目的探讨混合性性腺发育不良(mixed gonadal dysgenesis,MGD)患儿的临床特点、导致误诊的原因及处理方式。方法回顾性分析2013年5月至2018年4月收治的24例MGD患儿的临床资料。24例患儿的年龄在10~39个月,平均21个月;身高71~97 cm,平均83 cm,其中10例患儿身高低于同年龄段平均身高2个标准差;就诊时22例抚养性别为男,2例抚养性别为女。Prader分级Ⅱ级3例,Ⅲ级15例,Ⅳ级6例。分析患儿性激素测定、性发育相关基因检测结果。对8例常规核型分析性染色体为46,XY的患儿采用荧光原位杂交(fluorescence in situ hybridization,FISH)方法复测,光学显微镜观察患儿切除或活检的性腺组织。结果本组患儿AMH值在16.57~189.92 ng/ml,均值为69.42 ng/ml;hCG刺激实验后睾酮值在0.71~8.09 nmol/L,均值为4.93 nmol/L。基因检测发现WT1基因致病突变,合并低蛋白血症和蛋白尿1例,诊断为Denys-Drash综合征。核型分析示,12例核型为45,X/46,XY,10例为46,XY(其中8例完成FISH检查证实性染色体为X嵌合XY),1例为45,X/46,XY/47,XYY,1例为45,X/47,XYY/48,XYYY。24例均存在阴道,22例探查到子宫或半角子宫。送检48份性腺组织,其中24份有发育不良的睾丸,其中1份睾丸性腺中可见未分化性腺组织。19份有纤维条索性腺,1份未分化性腺组织曾被误诊为卵巢。4份可见条索状性腺伴性索状结构。所有性腺组织均未见肿瘤征象。结论MGD患儿以外阴性别模糊多见常伴苗勒管残件。临床中对考虑诊断MGD的患儿不能仅采用染色体核型分析,可疑者应完善外周血FISH性染色体嵌合型检查。MGD患儿性腺病理检查可见未分化性腺类型,病理易将其识别为卵巢组织,从而将混合性性腺发育不良误诊为卵睾型DSD。     

儿童真两性畸形诊断与治疗:附9例报告

目的 探讨儿童真两性畸形的诊断、合理的性别选择及恰当的治疗方式。方法 回顾性分析1994年至2002年9例儿童真两性畸性的临床资料。结果 社会性别：男6例，女3例；染色体组型：46XX4例，46XY1例，45XO1例，45XO／46XY嵌合型3例。性腺畸形为：双侧型2例，单侧型3例，片侧型4例。按男性抚育者，行卵巢组织及子宫附件切除，睾丸固定，同期或二期尿道下裂修复；按女性抚育者，切除睾丸组织或卵睾，同期行阴蒂会阴成形术。近期2例用腹腔镜行盆腔探查和性腺切除。5例获得6个月～3年的随访。结论 早期诊断、根据外生殖器及性腺优势作出合理的性别选择至关重要，儿童期应完成对与确定性别相抵触性腺的切除和外生殖器矫形，腹腔镜在诊断与治疗上有很好的价值。     

41例46,XY性别发育异常临床诊治及基因筛查结果分析

目的探讨儿童46,XY性别发育异常的诊疗策略,并总结其诊疗经验。方法回顾性分析41例2011年9月至2018年11月于中国医科大学附属盛京医院确诊为46,XY DSD患儿的临床表现、实验室及影像学检查结果、基因检测结果和病理结果等资料,并总结其临床特征。结果41例中社会性别男28例(68.3%),女13例(31.7%),初诊年龄3个月至15岁。外生殖器完全女性化3例,外生殖器明显男性化17例,外生殖器模糊21例。染色体检查结果均为46,XY,且SRY基因阳性。35例行HCG激发试验,23例行性别发育相关基因筛查,8例行组织学检查。其中性腺发育异常17例,雄激素合成或作用缺陷16例,苗勒氏管永存综合征6例,Kallmann综合征2例。6例接受性腺切除术,10例接受外生殖器整形术,11例接受睾丸固定术,2例接受性别重新认定,10例未进行性别选择,其余29例维持原来社会性别。结论46,XY DSD患儿临床表现个体间差异较大,除性腺发育异常及睾丸消失综合征外,其余患儿最终需要结合基因检测结果以明确诊断。性别选择是46,XY DSD治疗的关键,需要全面评估后进行慎重选择。对于睾丸功能良好的患儿,最好让患儿自己参与性别的选择,尽量避免不可逆的性腺切除及外生殖器手术。     

外生殖器畸形106例患儿病因分析

目的 分析外生殖器畸形患儿的临床特征并探讨其发病原因,以期提高该病的诊疗水平.方法 收集近几年因外生殖器畸形就诊于上海交通大学医学院附属瑞金医院的106例患儿的资料,总结其临床特征、行染色体核型分析及其他辅助检查.部分患儿抽提外周血基因组DNA进行相关基因突变筛查.结果 (1)106例外生殖器畸形患儿表型多样,从单纯阴蒂肥大/单纯尿道口开口异常,到外生殖器呈间性畸形、性别难辨.染色体核型分析:46,XX 42例(39.6％);46,XY 62例(58.5％);2例(1.9％)染色体核型异常.(2)42例46,XX核型患儿诊断为先天性肾上腺皮质增生症(CAH) 40例(95.2％),肾上腺肿瘤1例(2.4％),另有1例(2.4％)患儿性别决定基因(SRY)阳性.(3)46,XY核型中的53例(85.5％)行5α-还原酶2型基因(SRD5A2)、雄激素受体基因(AR)和类固醇生成因子-1基因(SF-1)突变筛查,发现8例患儿存在SRD5A2突变,存在AR和SF-1突变者各1例.(4)2例染色体异常患儿,1例染色体核型为46,XX/46,XY嵌合型;1例为46,XX/46,XY/46,X.+may.ish(DYZ3+)(DXZ1-)嵌合型.结论 (1)CAH是46,XX核型中呈现外生殖器畸形最常见的病因,少见因素如肾上腺肿瘤、SRY易位等.(2)46,XY核型的外生殖器畸形发病机制复杂,基因突变筛查是明确其病因的最有效方法.(3)染色体异常亦可以引起外生殖器畸形表型.     

The clinical and genetic heterogeneity of mixed gonadal dysgenesis: does “disorders of sexual development (DSD)” classification based on new Chicago consensus cover all sex chromosome DSD?

Clinical findings illustrate the wide spectrum of the phenotypic manifestations of 45,X/46,XY mosaicism in the sex chromosome disorders of sex differentiation (DSD). The objective of study is to evaluate the characteristics of 45,X/46,XY patients and questioning of their place within the DSD categorization. The clinical findings of 11 patients with 45,X/46,XY mosaicism are described including the presentation, gonadal morphology, genital anatomy, and the hormone levels among 285 patients with DSD evaluated. Sixty-seven patients were diagnosed with sex chromosome DSD (50 Turner, three Klinefelter, ten 45,X/46,XY gonadal disgenesis, one 45X/46,XY ovotesticular DSD, one 47,XYY ovotesticular DSD, and two 46,XX/46,XY ovotesticular DSD). The type and the percentage of patients with 45,X/46,XY mosaicism were as follows: Four cases of mix gonadal dysgenesis, four cases of partial gonadal dysgenesis, two cases of complete gonadal dysgenesis, one case of ovotesticular DSD. On the other hand, another patient that has 45,X/46,XX mosaicism was diagnosed with MGD with the presence of the streak gonad on the right side and the testis on the other side. Conclusion: We suggest that sex chromosome DSD categorization can include 45,X/46,XY PGD and 45,X/46,XY CGD. Mixed gonadal dysgenesis may be also placed among the disorders of testicular differentiation of 46,XY DSD subdivision.     

Impact of laparoscopy for diagnosis and treatment in patients with disorders of sex development

ObjectiveTo review laparoscopy in patients with disorders of sex development (DSD) in order to clarify its usefulness in diagnosis, devising subsequent therapeutic strategies and managing patients with various conditions.Patients and methodsBetween April 1992 and December 2012, 29 laparoscopic surgeries were performed in 25 DSD patients. Among them, ten were diagnostic laparoscopy including gonadal biopsy, and 19 were therapeutic laparoscopy. Surgical procedures and complications were evaluated.ResultsFor diagnostic laparoscopy, laparoscopic gonadal biopsy was performed in three patients. Inspection, with or without open gonadal biopsy, was performed on four out of seven patients with 46XY DSD or mixed gonadal dysgenesis (MGD). Additional surgery was planned and performed based on diagnostic laparoscopic findings in six out of seven patients. In the three patients with ovotesticular DSD, the gonadal pathology was diagnosed as: testis/ovary in one, testis/ovotestis in one and ovary/ovotestis in one – this was from the laparoscopic inspection and/or gonadal biopsy. However, the final diagnoses were bilateral ovotestis in two patients and ovary/ovotestis in one patient.For therapeutic laparoscopy, surgical procedures were: gonadectomy in 17 patients (bilateral in 13, unilateral in three, partial in two); hysterectomy in two patients; orchiopexy in one; and sigmoid vaginoplasty in one patient (included multiple procedures). There were no severe perioperative complications. In the four patients with a history of diagnostic laparoscopy, no severe intra-abdominal adhesions that would disturb therapeutic laparoscopic surgery were observed.ConclusionWhile diagnostic laparoscopy was helpful in devising a therapeutic surgical strategy in most of the patients with DSD who were suspected as having complex gonadal status or Müllerian duct derivatives, attention must be paid to precisely diagnosing the gonadal status in ovotesticular DSD. On the other hand, therapeutic laparoscopic surgeries were valuable procedures in treating DSD patients, even with a history of previous diagnostic laparoscopy.     

Disorders of gonadal development: a broad clinical, cytogenetic and histopathologic spectrum

The most complicated group of sexual differentiation disorders is that of gonadal development. Disorders of gonadal development form a wide clinical, cytogenetic and histopathological spectrum. There are still some unsolved difficulties of diagnosis, development of malignancy and the sex rearing of these patients. We reviewed 23 cases of gonadal developmental disorders among 169 patients with ambiguous genitalia or delayed puberty. Among 169 patients, 87 patients were 46,XY disorders of sex development (DSD), 59 patients were 46,XX DSD without disorders of gonadal development and the remaining 23 patients had disorders of gonadal development. Nine of these 23 patients were diagnosed as 46,XY gonadal dysgenesis, 7 patients had ovotesticular DSD, 5 patients had 45,X/46,XY mixed gonadal dysgenesis. Fourteen patients with disorders of gonadal development had genital ambiguity, 5 patients had a female genital phenotype with a palpable gonad and/or delayed puberty. Four patients had the male genital phenotype. Disorder of gonadal development is a very important clinical problem with different aspects of diagnosis, treatment, rearing sex and prophylaxis. Each patient should be evaluated individually employing a multidiciplinary approach.     

Pediatric disorders of sex development

The management of disorders of sexual differentiation (DSD) involves a multidisciplinary approach. The main aim of analysis was to study the phenotype-karyotype correlation in North Indian children with DSD. The records of pediatric DSD were retrieved and characteristics noted. Of total of 58 children, 43 (74.1%) and 10 (17.2%) were raised as males and females respectively. The mean age at presentation was 31.3±9 months. The karyotype was 46XY in 45 (77.6%) and 46XX in 12 (20.7%). CAH was commonest cause of DSD (36.2%), followed by gonadal dysgenesis. Of the 15 patients of 46 XY CAH, there were 5 with 17-α hydroxylase deficiency, 2 with 3-β HSD deficiency and one case of lipoid adrenal hyperplasia. There was an excess of genetic males, possibly due to prevalent socio-cultural factors and gender bias favoring males. There is a need to improve the diagnostic facilities and incorporate a team approach in management of DSD.     

尿生殖窦部分游离术在雄性化46,XX性别发育异常治疗中的应用

目的 探讨尿生殖窦部分游离术在雄性化46,XX性别发育异常(disorders of sex development,DSD)女性化手术中的应用,并对其疗效进行评估.方法 2010年5月到2015年2月,我院收治15例过度雄性化的46,XX DSD患儿,采用尿生殖窦部分游离(partial urogenital mobilization,PUM)术结合Poppas阴蒂整形术和阴唇成形术一期完成生殖器女性化手术.年龄5个月～13岁,中位年龄28.7个月.通过膀胱镜下测量尿生殖窦共同通道的长度,来决定是否实施PUM术.术后随访尿控情况、阴道口大小和位置及外阴外观等来判断PUM的疗效.结果 15例均获随访.随访时间1～5年,平均31.5个月.尿生殖窦共同通道长度1.2～3.0cm,平均1.7cm.外生殖器外观评估:12例(80％)为好,前庭部可见阴道开口,阴道内可进入8～15 mm的阴道扩张器(平均10mm).2例(13.3％)为一般,其中1例小阴唇偏短;另1例术后阴道口位置较深.不满意1例(6.7％),为尿生殖窦共同通道长度近3 cm的Prader V级患儿,术后阴道口较深,大阴唇外观皮肤冗多似阴囊,小阴唇偏短.但无一例出现阴道口狭窄.无一例出现尿失禁及尿频、排尿困难等下尿路症状;13例在术后1年以上做了尿流动力学检查,除3例有部分逼尿肌不稳定收缩外,余均无明显异常.结论 尿生殖窦共同通道长度小于2 cm的雄性化46,XX DSD,PUM术是治疗该畸形的有效方法,术后可获得开口于前庭的无狭窄的阴道、良好的尿控和满意的外生殖器外观.     

Gender assignment and hormonal treatment for disorders of sexual differentiation

Purpose  To study the gender assignment and hormonal treatment advocated for disorders of sexual differentiation (DSD). Methods  A study was done on patients who were reviewed in the Pediatric Intersex Clinic to evaluate the pattern of gender assignment and hormonal treatment advocated. Results and conclusion  The patients included male pseudohermaphrodite (MPH) 169; congenital adrenal hyperplasia (CAH) 91; mixed gonadal dysgenesis (MGD) 29; true hermaphrodite (TH) 25; pure gonadal dysgenesis (PGD) 2; persistent mullerian duct syndrome (PMDS) 2 and others (micropenis, severe hypospadias with cryptorchidism, 46XX male) 39. Out of 91 cases of CAH, 70 (76.9%) were on steroids (prednisolone, hydrocortisone) and/or mineralocorticoids (fluoricortisone) for adrenal suppression. Out of 146 cases of male pseudohermaphrodite and 21 cases of true hermaphrodite and 3 cases of mixed gonadal dysgenesis reared as males, testosterone was given for local application for phallic growth in 101 and/or as systemic injection for mental makeup after puberty in 41 cases. Systemic testosterone injection was also given for 7 cases of CAH reared as males. Out of 26, 15 cases with mixed gonadal dysgenesis and one out of 2 cases of pure gonadal dysgenesis that attained puberty after being reared as females, after female genitoplasty, were given conjugated oestrogen (Premarin) supplemented with progesterone, as the uterus was preserved. For 12 post-pubertal cases of complete androgen insensitivity syndrome (AIS), only premarin was given as there was no uterus. Growth hormone and Gn RH analogue was given in 2 patients with CAH to tide over the early bone maturation induced by hormones with equivocal results. Thus judicious hormonal supplementation based upon type of DSD and gender assigned can provide a psychological and cosmetic benefit to patients with DSD.     

先天性肾上腺皮质增生症致46XX性发育异常的外科治疗分析

目的 探讨先天性肾上腺皮质增生症(CAH)致儿童46,XX性发育异常(DSD)外科治疗最佳手术时机、手术方式及外科治疗效果.方法 回顾性分析2008年1月至2015年1月我院收治CAH致儿童46,XXDSD患儿共39例,18例定期门诊随访纳入本次研究,年龄1岁2个月～13岁3个月,平均4岁2个月,中位年龄3岁,随访时间3个月～7年.2例患儿仅表现为阴蒂肥大,行阴蒂整形术.16例同时伴有尿生殖窦共同开口,长度为0.5～4.0 cm,平均1.0 cm.8例阴道成形同时行尿道口前移;8例仅阴道成形术,未行尿道口前移.结果 15例术后会阴整体形态满意,3例因自行停用激素出现阴蒂肥大,18例患儿阴蒂触觉及温热觉正常;8例阴道成形、尿道口前移患儿中6例阴道口大小位置可;2例未遵医嘱行阴道扩张出现阴道狭窄;2例出现尿道口退缩;1例尿道阴道瘘.8例阴道成形患儿阴道口位置正常;2例未阴道扩张出现阴道狭窄.结论 CAH致儿童46,XXDSD最佳手术时机及手术方式仍存在争议.早期阴蒂整形术可以获得良好的会阴外观,且保持阴蒂的感觉功能;建议诊断明确及激素水平控制后尽早手术,最好于学龄前完成;早期阴道成形术后拥有满意疗效,但可能出现阴道狭窄,定期阴道扩张可能有助于减少阴道狭窄的发生;尿道口前移术后可能出现尿道口退缩、尿道阴道瘘等并发症.手术时机及手术方式需根据患儿激素水平、会阴发育情况及手术单位医疗水平综合进行考虑.
