Incidentally Discovered Persistent Müllerian Duct Syndrome in a 45-year-old male presenting with germ cell tumor and bilateral cryptorchidism: A rare case report and review of the literature

Misdiagnosis and mistreatment of transverse testicular ectopia-two case report and review of literature

RATIONALE

Transverse testicular ectopia (TTE) is a rare congenital malformation with a high rate of misdiagnosis and mistreatment before operation, which cannot be diagnosed even during operation due to lack of knowledge.

PATIENT CONCERNS

Two patients with ectopic testes who were misdiagnosed as right inguinal hernia for the first time and underwent surgery. The "ovary" and "testicle" like structures was seen in the right inguinal region during the first operation. After being transferred to our hospital for laparoscopic surgery, it was found that the left spermatic cord and testis were transversely transverted to the right, the left testis was fixed at the right inner ring, and agglomerated soft tissue could be seen in the right inguinal canal, which was suspected to be Muller tube.

DIAGNOSES

Based on preoperative images and intraoperative findings, both cases were diagnosed with Transverse testicular ectopia (TTE). The postoperative pathology report for the second patient revealed the presence of an in situ spermatogenic cell tumor in the ectopic testis.

INTERVENTIONS

Preperitoneal tension-free repair of right inguinal hernia and resection of left cryptorchidism were performed on the 2 patients.

OUTCOMES

Postoperative pathology of the first patient confirmed that the resected specimens contained tubal-like and uterine-like structures. The postoperative pathology of the second patient showed that the resected tissue consists of immature testis, epididymis, uterus and seminal vesicle glands, in which an in situ spermatogenic tumor could be seen in the testicular tissue. Postoperative diagnosis: left transversal testicular ectopia and right indirect inguinal hernia.

LESSONS

The clinical misdiagnosis and mistreatment rate of TTE is very high. Once the patients with cryptorchidism complicated with inguinal hernia are found in clinic, the possibility of the disease must be considered. For the patients whose cryptorchidism does not descend into the ipsilateral scrotum and it is difficult to diagnose, laparoscopy can be used for both diagnosis and treatment. If a patient has both inguinal hernia and cryptorchidism, it is crucial to rule out a diagnosis of TTE to prevent misdiagnosis and inappropriate treatment.

Identification of four novel variant in the AMHR2 gene in six unrelated Turkish families

PURPOSE

Persistent Müllerian duct syndrome (PMDS) is characterized by the persistence of Müllerian structures in male with normal phenotype. Most cases occur as a result of mutations in the anti-Müllerian hormone (AMH) or AMHR2 genes. In this study, we aim to discuss the results of clinical, laboratory, and molecular genetic analysis of cases detected to have AMHR2 gene mutation.

METHODS

A total of 11 cases from 6 families were included in the study. AMHR2 gene mutation analyses were performed by sequencing of the coding exons and the exon-intron boundaries of the genes. The American College of Medical Genetics guidelines were used for the classification of the detected variants.

RESULTS

Six of the 11 cases were admitted due to bilateral undescended testes and five cases due to inguinal hernia (three transverse testicular ectopia and two hernia uterus inguinalis). All cases had normal AMH levels. Seven different variants were identified in the six families. The variants detected in four cases were considered novel (c.78del, c.71G > A, c.1460dup, c.1319A > G). Two of the novel variants were missense (exon 2 and exon 10) mutations, one was deletion (exon 2), and one duplication (exon 11).

CONCLUSION

We identified four novel mutations in the AMHR2 gene resulting in PMDS. Duplication mutation (c.1460dup) in the AMHR2 gene causing PMDS was demonstrated for the first time. The most important complications of PMDS are infertility and malignancy. Early diagnosis is vital to preventing malignancy. Vas deferens and vascular structures may be injured during orchiopexy. Therefore, patients should always be referred to experienced clinics.

Bilateral intra-abdominal testicular tumor: Case report

INTRODUCTION

Bilateral intra-abdominal testis is a very rare clinical entity. These testes may develop cancer in an adult patient with empty scrotum.

CASE PRESENTATION

A case of a huge intra-abdominal solid mass in a 32-year-old gentleman is presented. Physical examination revealed an empty scrotum. Laboratory investigations, imaging studies, laparotomy and histopathological examination showed that the solid mass was a mixed germ cell tumor of the left testis. The contra-lateral testis also had a tumor. Resection of the solid mass and contra-lateral orchiectomy was performed. Adjuvant chemotherapy was given. Six months after surgery, his follow-up parameters were all within normal limits.

DISCUSSION

Since bilateral intra-abdominal testis tumor is a very rare clinical entity, there are no patient management guidelines available. Management strategies differ significantly among groups and they are based mainly on the experience reflected in the context of anecdotal case reports.

CONCLUSION

Surgical exploration and adjuvant chemotherapy seems as a reasonable treatment option in the setting of bilateral intra-abdominal testis tumor in an adult patient.
