We report the case of a 35-year-old patient with a syndrome of persistent Müllerian ducts (PMDS) of the female type (group A). The diagnosis was made in adulthood during an infertility workup. Clinical examination revealed an empty scrotum, a normal penis and bilateral inguinal cystic masses. The spermogram found azoospermia. Imaging using MRI and tomotensidometry found the presence of an uterus, two fallopian tubes and two inguinal positions of polycystic testes. A surgical management was performed for surgical testicular biopsy. Histological examination then found a cystic formation of multi-celled mesothelial origin, with atrophic testis Sertoli cell involution and without sperm. PMDS is a rare form of pseudo-internal hermaphroditism characterized by the presence in a man of the uterus, fallopian tubes and upper vagina with external male genitalia and virilized characters. About 200 cases are reported in the literature. The diagnosis is often made in children intraoperatively during a cure of testicular ectopia. The karyotype is 46 XY type. The pathogenesis is related to a deficiency of anti-Müllerian hormone (AMH) or tissue resistance to its action by receptor abnormalities. The regression of the Müllerian duct derivatives can give three types of PMDS : masculine type, feminine type and a transverse type. Surgical treatment is difficult but necessary because of the risk of infertility and ectopic testicular degeneration.
我们报告了一例35岁女性型持续性苗勒管综合征(PMDS,A组)患者的病例。该诊断是在成年期不孕检查期间做出的。临床检查发现阴囊空虚、阴茎正常以及双侧腹股沟囊性肿块。精液分析发现无精子症。MRI成像和张力测量法检查发现存在子宫、两条输卵管以及双侧腹股沟位置的多囊性睾丸。为进行手术睾丸活检实施了手术治疗。组织学检查随后发现了起源于多细胞间皮的囊性结构,睾丸萎缩,支持细胞退化,且无精子。PMDS是一种罕见的假性两性畸形形式,其特征为男性体内存在子宫、输卵管和上段阴道,同时伴有外生殖器男性化和男性化特征。文献报道约有200例病例。诊断通常在儿童期睾丸异位矫治手术中做出。核型为46 XY型。发病机制与抗苗勒管激素(AMH)缺乏或组织因受体异常而对其作用产生抵抗有关。苗勒管衍生物的退化可导致三种类型的PMDS:男性型、女性型和横型。由于存在不孕和异位睾丸退化的风险,手术治疗虽困难但很有必要。
