Diagnostic and therapeutic challenges with germ cell tumours associated with transverse testicular ectopia and persistent Müllerian duct syndrome.

Transverse testicular ectopia (TTE) is an infrequent ectopic testis where both testes descend via the same inguinal canal, located in the same hemiscrotum, and augments the risk of developing testicular tumours. Type II TTE is accompanied by persistent Müllerian duct syndrome, where the Müllerian structures persist for various reasons. Here, we present a case of an adult in his early 30s, who presented with a right testicular swelling and was diagnosed as type II TTE and testicular mixed germ cell tumour after surgery. We could find only 13 similar cases of TTE and testicular tumours in the literature. Our case highlights the importance of clinical acumen with detailed history, meticulous clinical examination, radiological investigations and a detailed pathological examination while dealing with such sporadic presentations.

Non-classical lipoid adrenal hyperplasia presenting as hypoglycemic seizures.

Introduction Primary adrenal insufficiency is a potentially life-threatening condition that can have many underlying causes. Mutations in the steroidogenic acute regulatory protein (StAR) gene produce lipoid congenital adrenal hyperplasia (LCAH) which usually presents in the infantile period with severe symptoms of adrenal insufficiency. Less commonly, a non-classical form is identified which may present at a later age in affected individuals. Till date, around 30 individuals with the non-classical form have been described. Case presentation We describe a 4-year-old 46, XX Indian girl who presented with hypoglycemic seizures and was subsequently diagnosed as non-classical LCAH on genetic analysis, with homozygous R188C mutation in the StAR gene. Conclusions StAR mutations may have a variety of clinical presentations and are likely under-diagnosed. Genetic diagnosis is important for treatment as well as monitoring of reproductive function.

A Simplified Management of Transverse Testicular Ectopia in Patients with Persistent Mullerian Duct Syndrome.

Persistent müllerian duct syndrome (PMDS) in the majority of cases is discovered during surgery for inguinal hernia or cryptorchidism. A transverse testicular ectopia (TTE) with cryptorchidism may be very rarely associated to PMDS. Assuming that müllerian remnants have a very low malignant degeneration potential if compared to the malignancy risk of an undescended and not relocated testis, we describe a simplified surgical technique of orchiopexy that avoids an extensive anatomical dissection, in this way minimizing the risk of losing the deferential blood supply to the testis.

Pregnancy and Live Birth In Women With Pathogenic LHCGR Variants Using Their Own Oocytes.

CONTEXT: The LH/chorionic gonadotropin receptor (LHCGR) is mainly expressed in gonads and plays important roles in estradiol production, ovulation, and luteal formation. Women with pathogenic LHCGR variants suffer from infertility, and successful fertility treatments for such women have never been reported. OBJECTIVE: The purpose of this study was to determine whether women with pathogenic LHCGR variants can achieve successful pregnancies through in vitro fertilization. DESIGN: Three women with LH resistance and infertility and their parents underwent exome sequencing. The biochemical characteristics and functional effects of LHCGR mutation were assessed in transfected human embryonic kidney -293T cells and primary granulosa cells. RESULTS: All affected women harbored pathogenic LHCGR variants. The LHCGR variants lacked cell surface localization and signal transduction abilities in vitro and in vivo. After dual triggering and prolonging the interval between triggering and oocyte pick-up, all three patients achieved oocytes and high-quality embryos. After frozen embryo transfer, one woman successfully birthed twins, and one woman successfully birthed a live boy. Apart from difficulties in oocyte retrieval, no obvious abnormalities in fertilization or during embryo development and pregnancy were identified in these patients. CONCLUSIONS: This study is, to our knowledge, the first to report successful assisted reproductive treatment of women with pathogenic LHCGR variants using their own oocytes. Our results supported that defects in LHCGR disrupted ovulation but had no effect on fertilization and embryo development.

Transverse testicular ectopia associated with persistent Müllerian duct syndrome treated by transseptal orchiopexy: A case report.

RATIONALE: Persistent Müllerian duct syndrome (PMDS) is rare form of male pseudohermaphroditism characterized by the presence of uterus and fallopian tubes with normal external genitalia and secondary sexual characteristics. Transverse testicular ectopia (TTE) is also a rare form of testicular ectopia that may be associated with PMDS. PATIENT CONCERNS: We present a 2-year-old boy who presented with bilateral non-palpable testes with left inguinal mass. DIAGNOSIS: TTE with PMDS. INTERVENTIONS: On exploration, both testes were present in the left inguinal region. Uterus and fallopian tubes were located between the testes. A hysterectomy was perfomed with resection of the underdeveloped fallopian tubes. Bilateral orchiopexy was performed by placing both gonads into subdartos pouches in each scrotum with transseptal approach. OUTCOMES: Both testes were palpable in both the scrotum at 1-year postoperative follow-up and we are planning a regular follow-up. LESSONS: In case of TTE with PMDS, optimal surgical approach with orchiopexy and excision of Müllerian duct should be needed. A long-term postoperative follow-up is necessary for assessment of malignant transformation and infertility.

[A rare cause of cryptorchidism, the persistence of müllerian ducts syndrome]. / Une cause rare de cryptorchidie le syndrome de persistance des structures müllériennes.

The Persistent Müllerian Ducts Syndrome (PMDS) is a rare congenital syndrome. It is one of abnormalities of genito-sexual development that is found on the normally virilized boy (46XY). It is characterized by the development of both Wolf structures and Müller duct. The pathophysiology can be explained by an action deficit of the anti-müllerian hormone (AMH). Its clinical presentations vary depending on the localization of the testis and the associated symptoms. Its discovery is mostly fortuitous and generally made in per-operative surgery of cryptorchidism or inguinal hernia. Treatment should be surgical. It relies on two aspects : ensuring the testicular descent and performing the excision of the müllerian duct. The follow-up is identical to the cryptorchid testes and the fertility problems will be influenced by the surgical procedure as well as the timing of the treatment.

Le syndrome de persistance des canaux mullériens (PMDS) est un syndrome congénital rare donnant des anomalies du développement génito-sexuel chez le garçon normalement virilisé (46XY). Il se caractérise par le développement à la fois des structures de Wolf et des canaux de Müller. Sa physiopathologie s'explique par un défaut d'action de l'hormone anti-müllérienne (AMH). Il existe différentes présentations cliniques qui varient en fonction de la localisation du testicule et des symptômes associés. Sa découverte est fortuite et généralement faite en per-opératoire d'une chirurgie de cryptorchidie ou d'hernie inguinale. Le traitement doit être chirurgical. Il repose sur deux aspects : assurer la descente testiculaire et réaliser l'exérèse des canaux müllériens. Le suivi est identique à celui d'un testicule cryptorchide et le risque de trouble de la fertilité varie en fonction de l'âge de prise en charge et du geste chirurgical.

Prostatic adenocarcinoma in the setting of persistent müllerian duct syndrome: a case report.

Persistent müllerian duct syndrome (PMDS) is a form of disordered sex development in which rudimentary müllerian structures are identified in phenotypically and genotypically normal males. It is caused by defects in the anti-müllerian hormone (AMH) system. Since patients with PMDS present with undescended testes, testosterone production by Leydig cells later in life is often decreased. The role of androgens in prostate cancerogenesis is well known. Cryptorchid testes and diminished testosterone levels in post-pubertal life in patients with PMDS play a protective role against prostate cancer, and hence, prostate cancer is a rare event in patients with PMDS. Herein, we present a patient who underwent prostatectomy for high-grade prostatic adenocarcinoma with persistent müllerian structures (such as rudimentary uterus, fallopian tubes, and cervix) identified during surgery. To our knowledge, this is the second case reported in the English language literature where PMDS was associated with prostate cancer.

Coincidence of Persistent Müllerian duct syndrome and testicular tumors in dogs.

BACKGROUND: Persistent Müllerian duct syndrome (PMDS), a rare form of male pseudohermaphroditism in dogs, is an abnormal sexual phenotype in males that is characterized by the existence of a hypoplastic oviduct, uterus, and cranial part of the vagina. Dogs suffering from PMDS are often accompanied by cryptorchidism. To date, it has been mainly found in the Miniature Schnauzer breed. CASE PRESENTATION: In this report, two cases of PMDS with a malignant testicular tumor originating from cryptorchidism in breeds other than the Miniature Schnauzer breed are described. The patients were a seven-year-old male Maltese dog and a 17-year-old male mixed-breed dog weighing 3.8 kg. They also exhibited an enlarged prostate with or without abscess and an elevated serum estradiol level and were surgically treated to remove the testicular tumor and Müllerian duct derivatives. CONCLUSIONS: It is recommended that PMDS should be differentially diagnosed by ultrasonography and that orchiectomy be performed at an early age in patients suspected to have cryptorchidism to prevent the ectopic testes from becoming tumorous.

[Persistent mullerian duct syndrome : Rare incidental finding during treatment of pediatric inguinal hernia]. / Das persistierende Müller-Gang-Syndrom : Ein seltener Zufallsbefund bei der Versorgung kindlicher Leistenhernien.

BACKGROUND: Persistent mullerian duct syndrome (PMDS) is a rare, autosomal recessive disorder. It is a form of male disorder of sexual differentiation in which mullerian duct structures are present in male phenotypes and 46XY karyotypes. In affected individuals, uterus, fallopian tubes, cervix and vagina are present. METHODS: A 2-month-old boy was admitted to hospital with a right-sided inguinal hernia. The physical examination showed a phenotypically normal boy with a right sided indirect inguinal hernia and impalpable testis. During herniotomy, a uterus and two fallopian tubes were found in the pelvic peritoneum adjacent to the two gonads. Initial biopsies were taken from the gonads and blood was sent for karyotyping. RESULTS: The biopsy showed normal testicular tissue without any ovarian tissue and the karyotyping result was 46XY; therefore, the diagnosis of persistent mullerian duct syndrome (PMDS) was made. In a second laparoscopically assisted operation the uterus and fallopian tubes were dissected, an orchidopexy of the left testis and an orchiectomy of the right testis were performed. The postoperative course was uneventful. CONCLUSION: In the case of an incarcerated inguinal hernia in combination with impalpable testis, a PMDS should be considered as a differential diagnosis.

[Intra-Abdominal Germ Cell Tumor in Persistent Mullerian Duct Syndrome].

A 46-year-old man was admitted to hospital presenting with a lower abdominal mass. The patient's testes were not palpable in the scrotum, and the levels of lactic dehydrogenase, α-fetoprotein and human chorionic gonadotropin were all elevated. Enhanced computed tomography revealed that the lumen of the mass had penetrated the prostate. Pathological analysis of biopsy tissue indicated that the mass was a seminoma. Residual tumor resection was performed after chemotherapy. On histological examination, the lumen proved to be a Mullerian structure. Our diagnosis was an intra-abdominal germ cell tumor and persistent Mullerian duct syndrome.

Gonadal malignancy in 202 female patients with disorders of sex development containing Y-chromosome material.

The objective of this study was to examine risks for gonadal malignancy in a large sample of adult female patients with disorders of sex development (DSD). A retrospective-observational study was conducted from July 1992 to March 2015 and 202 women with DSD were enrolled. Tumor risks for different types of DSD were measured. We found that the patients' total gonadal-malignancy risk was 18.3% (37/202). Tumors included gonadoblastoma (n = 11), seminoma (n = 8), dysgerminoma (n = 5), choriocarcinoma (n = 1), sertoli cell tumors (n = 11), and leydig cell tumors (n = 1). The incidence of gonadal malignancy in patients with complete androgen insensitivity syndrome (CAIS), pure 46, XY gonadal dysgenesis, 45 X/46 XY mixed gonadal dysgenesis, 17α-hydroxylase/17, 20-lyase deficiency and partial androgen insensitivity syndrome (PAIS) were 27.1% (13/48), 22.4% (15/67), 10.9% (5/46), 10% (2/20) and 9.5% (2/21), respectively. Our results suggest that the incidence of gonadal malignancy increases with age for female patients with Y-chromosome material. Upon diagnoses, immediate, prophylactic gonadectomies should be considered for adult female patients with DSD containing Y chromosome material if they cannot receive regular follow-ups.

Vaginoplasty Using Human Amniotic Membranes A Report of Five Patients.

OBJECTIVE: To present our experiences with an innovative surgical approach for vaginal agenesis that uses amnion as the allograft to create a functional neovagina. STUDY DESIGN: This study involved 5 patients with diagnosed vaginal agenesis. One patient had karyotype 46,XY and was diagnosed with complete androgen insensitivity syn- drome, whereas the others had karyotype 46,XX and were diagnosed with Mayer-Rokitansky-Kiister-Hauser syndrome. All patients underwent Mclndoe vagino- plasty using amnion and were followed up at 2 weeks, 3 months, 6 months, and 12 months postsurgery. Functionality of the neovagina was assessed by Rosen Female Sexual Function Index (FSFI) questionnaire. RESULTS: At the 12-month follow-up 1 patient report- ed. an inability to use the vaginal dilator effectively; for the other 4 patients the mean depth of the neovagina was 9.5 cm and the mean width was 3.5 cm. The mean overall FSFI score was 28.3. CONCLUSION: McIndoe vaginoplasty is a simple, safe, and quick operative method that results in a ftnctional vagina. The amnion is a suitable material to apply to the surface of the neovagina because it is readily avail- able and does not have any associated immune reiection problems or costs.

[Persistent Müllerian ducts syndrome: one case of late hypofertility]. / Syndrome de persistance des canaux de Müller de type féminin : un cas de diagnostic tardif dans le cadre d'une infertilité

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.

Acute urinary retention caused by seminoma in a case of persistent Mullerian duct syndrome.

Urinary symptoms have been described secondary to a pelvic mass originating from the ovary, uterus, cervix, prostate, or rectum. Persistent Mullerian duct syndrome is a rare form of intersex disorder, characterized by the presence of uterus and fallopian tubes in an otherwise 46 XY male. We report an adult male with bilateral cryptorchidism and a pelvic mass, who presented with acute urinary retention, and was diagnosed with a seminoma of the right testis, intratubular germ cell neoplasia of the left testis with the presence of Mullerian remnants. Pelvic mass was caused due to seminoma is a rare cause of urinary retention.

Transverse testicular ectopia: a rare presentation with persistent Müllerian duct syndrome.

Undescended testes can be found in the inguinal channel or in the abdomen. Rarely, undescended testes can present with transverse testicular ectopia (TTE) and very rarely, with residual Müllerian duct (MD) structures. This latter presentation is called persistent MD syndrome (PMDS). PMDS is mostly discovered during surgery for inguinal hernia or cryptorchidism. TTE is a rare congenital anomaly in which both testes descend through a single inguinal canal. Patients with TTE present with symptoms of unilateral cryptorchidism and contralateral inguinal hernia. Herein, we report two TTE cases: one associated with PMDS and the other having only cross ectopia. For patients with inguinal hernia and cryptorchidism associated with TTE, PMDS should be kept in mind and radiologic evaluation with ultrasonography or magnetic resonance imaging of the genitourinary system and karyotyping are recommended. Radiologic evaluation can be helpful in the diagnosis of TTE; however, it cannot diagnose the malignancy itself. Laparoscopy is very useful for both diagnosis and treatment of TTE.

[Questions and dilemmas in the management of hypospadias]. / A hypospadiasis ellátásában felmerülo kérdések, dilemmák.

Hypospadias is the second most common congenital malformation in males. Etiology remains unknown in about 70% of the cases. Distal hypospadias is considered not only developmental abnormality of the urethra in males, but it may also constitute a mild form of sexual development disorder in 46,XY males. Most urologists and endocrinologists consider that it is necessary to perform a detailed investigation of children presenting with proximal hypospadias associated with a small phallus or poorly developed scrotum and undescended testes. Currently, there is no generally accepted recommendation for the preoperative evaluation of hypospadias and, therefore, masculinizing surgery without preoperative evaluation is performed in these children. The authors summarize the international literature data and their own experience for the assessment and management of hypospadias concerning questions and problems related to preoperative investigation, masculinizing surgery and additional surgery. A detailed algorithm is presented for preoperative evaluation of both proximal and distal hypospadias.

Persistent Mullerian duct syndrome with transverse testicular ectopia and seminoma.

Persistent Mullerian duct syndrome (PMDS) is a rare form of the 46 XY disorders of sexual differentiation, characterized by the presence of a uterus and fallopian tubes due to the failure of Mullerian duct regression in genotypically normal males. More than 150 cases have been recorded, most of them in adults. In most cases, the PMDS is discovered during surgery for inguinal hernia or cryptorchidism, or by the presence of transverse testicular ectopia (TTE). The presence of PMDS with TTE is even more uncommon. In TTE, both testes descend through the same inguinal canal into the same scrotal sac. Patients with TTE present with symptoms of unilateral cryptorchidism and a contralateral inguinal hernia. For patients with inguinal hernia and cryptorchidism associated with TTE, PMDS should be kept in mind, and radiologic evaluation such as ultrasonography or magnetic resonance imaging of the genitourinary system and karyotyping are recommended. Whereas radiologic evaluation could be helpful in the diagnosis of TTE, it cannot diagnose the malignancy itself. The case explained in this report will offer urologists additional useful treatment strategies for patients with inguinal hernia and cryptorchidism.
