Bilateral polyorchidism with ipsilateral two undescended testes: a rare congenital anomaly

Embryological basis of polyorchidism including classification, reproductive potential, and risk of malignancy: A review

Polyorchidism, a congenital malformation characterized by supernumerary testes (SNTs), is usually revealed incidentally during ultrasound or open scrotal surgery. In the approximately 200 cases so far published in the literature, the left side is affected more often than the right. Despite the rarity of this anomaly, a surgeon must have basic knowledge of its embryological basis and classifications to implement proper treatment and avoid overlooking it, since the consequences could harm the patient. This review summarizes previous classifications. It can be assumed that determining the risk of malignancy, and the level of reproductive potential based on location, vascularization, ductus deferens drainage, and environmental factors (e.g., temperature) affecting the SNTs, indicates the best approach to management. Therefore, we have created a new classification based on previous ones, addressing the aforementioned issues, which will guide the clinician to select the most appropriate treatment.

Polyorchidism: An Up-to-Date Systematic Review

Polyorchidism is a rare male urogenital tract anomaly characterized by at least one supernumerary testis in the scrotum or ectopically. According to data based on our systematic review, 76% of the supernumerary testes (SNTs) were located in the scrotum, and 24% were extra-scrotal (p < 0.001). Among testes located outside the scrotum, 87% were found in the inguinal canal and 13% in the abdominal cavity. In 80% of cases, the diagnosis of SNT was made based on imaging tests, and the remaining 20% of cases were detected incidentally during surgery. The imaging tests performed (US or MRI) resulted in a significantly higher rate of patients who qualified for observation vs. surgical treatment (45% vs. 35%, p < 0.001). The most common conditions associated with SNT were ipsilateral inguinal hernia (15% of cases) and cryptorchidism (15% of cases). Surgery (orchidopexy/orchidectomy) was performed on 54% of patients with SNT, and the decision to observe the SNT was made in a total of 46% of patients (p = 0.001). The therapeutic approach depends on the location of the SNT and the presence of factors that raise suspicion of neoplastic proliferation.

Case Report: Testicular Torsion in Unilateral Supernumerary Testis

Supernumerary testis (SNT), or polyorchidism, is a rare congenital anomaly of the genitourinary tract, described as the presence of more than two testicles. Testicular torsion (TT) in unilateral SNT is extremely rare. We report a case of unilateral SNT in a 16-year-old boy accompanied by TT, which was diagnosed preoperatively based on the outcomes of physical examination and ultrasound and confirmed intraoperatively. We opted for orchiectomy of this SNT because of the long-time hypoperfusion. And as for the normal testis, orchidopexy was performed. His clinical presentation subsided after surgery, and the patient was discharged 3 days later.

A rare case of polyorchidism in a 40-year-old man. A case report

Introduction

and importance Polyorchidism is defined as the presence of three testes or more. Approximately, there are about 200 cases of polyorchidism in the medical literature. In the past, surgical treatment was done but now with imaging studies, less aggressive approach is recommended.

Here we present a case of 40-year-old man who was diagnosed incidentally with polyorchidism in the right hemiscrotum which is quite unusual in this age.

Case presentation

A 40-year-old man presented to the emergency department with a swelling and pain in the left hemiscrotum. In palpation, we noticed a scrotal mass in the right hemiscrotum. His parents had first noticed a scrotal mass when he was two years old and was incorrectly diagnosed as hydrocele by an unauthorized practitioner.

In the left hemiscrotum, Doppler confirmed acute epididymitis diagnosis that was treated conservatively with antibiotics and NSAIDs. In the right hemiscrotum, MRI showed that the lump had separate epididymis and shared a common vas deferens with the right testis, which confirmed the diagnosis of supernumerary testis and the patient underwent a follow-up ultrasound after a month and after six months of his presentation.

Discussion

Triorchidism is the most common type of polyorchidism. Polyorchidism is diagnosed incidentally hence it is asymptomatic. There are many types of Polyorchidism and tow classification have been described. When the patient is asymptomatic the concentrative treatment is recommended.

Conclusion

Polyorchidism is a rare congenital anomaly in the genitourinary tract. It is diagnosed incidentally. Ultrasound or MRI are used to diagnose polyorchidism cases.

•

This Case Report is about a rare condition (polyorchidism) in a 40-year-old man which is very unusual in this age.

•

Diagnosis has been made by imaging studies only. No need for aggressive treatment in uncomplicated cases.

•

This case report provided a brief review about the classification of Polyorchidism and other differential diagnosis.

Neoplasm of a supernumerary undescended testis: A case report and review of the literature

•

Polyorchidism is a rare congenital abnormality. To the best of our knowledge, this is the first report of leiomyoma in supranumerary testis (SNT).

•

Most cases of polyorchidism are found incidentally during surgery for inguinal hernia, undescended testes, torsion or testicular tumor.

•

There is no consensus regarding the management of SNT. If the SNT is scrotal, most authors recommend conservative management.

•

If nonscrotal SNT is found incidentally during surgery, orchiectomy could be performed because of increased risk of malignancy.

•

Treatment of intratubular germ cell neoplasia includes surveillance, orchiectomy, or low-dose external radiation.

Introduction

Polyorchidism, defined as the presence of more than two testicles, is a rare congenital abnormality of the male genital tract. There is no consensus regarding the management of supranumerary testis (SNT) due to its rareness. To the best of our knowledge, this is the first report of leiomyoma in SNT.

Presentation of case

We report the case of a 41-year-old man with two right testes sharing a common vas deferens and separate epididymides. Orchiectomy of right testes was performed. Pathology examination found that the superior testis was the site of a leiomyoma and the lower tesits was the site of an intratubular germ cell neoplasia (IGCN). Orchiopexy and biopsy were later performed for the left testis. Histology was compatible with IGCN. We opted for follow-up to avoid risks of hypogonadism.

Discussion

Polyorchidism is usually asymptomatic and found incidentally during surgery for inguinal hernia, undescended testes as in our case, torsion, hydrocele or testicular tumor. If the SNT is scrotal, and there is no other indication for surgery, most authors recommend conservative management with regular ultrasound follow-up. If nonscrotal SNT is found incidentally during surgery, orchiectomy could be performed because of increased risk of malignancy. Treatment of IGCN includes surveillance, orchiectomy, or low-dose external radiation.

Conclusion

Different factors come into account for polyorchidsm management: the drainage system, the fertile potential of the supernumerary gonad, and its localization. In cases of uncomplicated polyorchidism, a conservative treatment, with US or MRI follow-up seems to be a rational choice without surgical complications.

Novel Variant of the Androgen Receptor Gene in a Patient With Complete Androgen Insensitivity Syndrome and Polyorchidism

Introduction: Complete androgen insensitivity (CAIS) in 65-95% cases is caused by pathogenic allelic variants (mutations) in the gene encoding androgen receptor (AR gene) and is characterized by female phenotype development with a male karyotype (46, XY). Patients are usually diagnosed during puberty and undergo gonadectomy due to increased testicular germ cell tumor risk. Only a few outcomes have been reported in older individuals with postponed gonadectomy. Case presentation: A 48-year-old CAIS patient presented with polyorchidism (four testes) without gonadal malignancies. Genetic testing identified a novel allelic variant in the AR gene [c.2141T>G (p.Phe805Cys)] causing the clinical symptoms. Conclusion: We have described a unique patient with CAIS and polyorchidism without malignancies in her late 40's bearing a novel likely pathogenic variant in the AR gene.

Management of Bilateral Undescended Bilobed Testes and Review of the Literature

Polyorchidism is a rare anomaly of testicular development. Particularly, a bilobed testis is an extremely rare congenital malformation, which is thought to be a variant expression of polyorchidism. Only 5 cases of bilobed testis have been reported in the literature to date. This report is of bilateral, undescended, bilobed testes in a 15-month-old boy who has multiple other malformations of possible genetic etiology.
