Congenital adrenal hyperplasia (CAH) is rare autosomal recessive disease. CAH due to 21-hydroxylase deficiency accounts for 95% of cases. We aimed to share the first case of coexistence of simple virilizing-type congenital adrenal hyperplasia [I172N mutation in the CYP21A], triple translocation [t(9;11;12)], and ovarian granulose cell tumor.
A 59-year-old female patient was presented to our clinic, complaining with abdominal pain and distension. Physical examination revealed palpable abdominal mass, virilism, ambiguous genitalia, clitoramegaly, and hyperpigmentation. Contrast-enhanced abdominal computed tomography showed a giant mass originating from the right tubo-ovarian structure.
The patient was operated in the light of the clinico-radiological features mentioned above. A giant mass weighing 3500 g was detected on the right tubo-ovarian structure during laparotomy, and mass was excised with right tubo-ovarian structure. Immunohistochemical examination revealed ovarian granulosa cell tumor. The high serum concentration of 17-OH progesterone was measured at baseline and after 250-μg bolus of synthetic ACTH. In genetic analysis, we screened for six-point mutations, large deletions, and non-common mutations using restriction fragment length polymorphism (RFLP) methods, PCR, and sequencing of CYP21 gene respectively. The patient was detected to be homozygous for the I172N mutation. In addition, 50% of the metaphases examined had triple translocation [t(9;11;12)].
The coexistence of congenital adrenal hyperplasia, triple chromosomal translocations, and ovarian granulosa cell tumor has not been described previously. This coexistence may be a sign of a new syndrome.
先天性肾上腺皮质增生症(CAH)是一种罕见的常染色体隐性遗传病。21-羟化酶缺乏引起的 CAH 占 95%。我们旨在分享首例单纯男性化型先天性肾上腺皮质增生症(CYP21A 的 I172N 突变)、三体型(t[9;11;12])和卵巢颗粒细胞瘤共存的病例。
一位 59 岁女性患者因腹痛和腹胀就诊于我院。体格检查发现可触及的腹部肿块、男性化特征、外生殖器模糊、阴蒂肥大和色素沉着过度。增强腹部计算机断层扫描显示起源于右侧输卵管卵巢结构的巨大肿块。
根据上述临床-影像学特征对患者进行了手术。剖腹术中发现右侧输卵管卵巢结构上有一个重达 3500g 的巨大肿块,并切除了肿块和右侧输卵管卵巢结构。免疫组织化学检查显示卵巢颗粒细胞瘤。基础和 250μg 合成 ACTH 冲击后,检测到血清 17-羟孕酮浓度升高。在基因分析中,我们使用限制片段长度多态性(RFLP)方法、PCR 和 CYP21 基因测序分别筛查了六点突变、大片段缺失和非常见突变。该患者被检测为 I172N 突变纯合子。此外,50%的中期分裂象存在三体型[t(9;11;12)]。
先天性肾上腺皮质增生症、三体型染色体易位和卵巢颗粒细胞瘤共存以前尚未描述。这种共存可能是一种新综合征的表现。
