Synchronous bilateral testicular cancer with discordant histopathology occurring in a 20-year-old patient: A case report and review of the literature

Testis sparing surgery for Leydig cell tumor, surgical approach, and clinical outcome: A case report and review of literature

Testicular Leydig cell tumors are rare neoplasms of the testes. These tumors are generally benign but malignancy and metastatic potential have been described. Here, we present a case of Leydig cell tumor in a 49-year-old male, incidentally discovered as a testicular mass. The patient had no significant previous medical history. Ultrasonography revealed a hypoechoic, well-defined, vascularized lesion measuring 7 × 7 × 4 mm adjacent to the tunica albuginea. The patient underwent testis sparing surgery, employing a modified approach including intraoperative ultrasound-guided localization, en-bloc wedge resection of the lesion with surrounding tunica albuginea and seminiferous tubules, and gubernaculum sparing surgery. Postoperatively, the patient had an uneventful recovery and was discharged on the same day. Histopathological examination confirmed the diagnosis of Leydig cell tumor, with no high-risk pathological features observed. Regular follow-up intervals were scheduled to monitor for potential recurrence, emphasizing the importance of vigilant postoperative surveillance in cases of testis-sparing surgery for Leydig cell tumors.

Bilateral Synchronous Testicular Cancer with Discordant Histopathology: A Case Report

Bilateral testicular tumors account for 1 to 5% of all testicular tumors. Most bilateral tumors are observed metachronously. Synchronous tumors usually present with the similar histological pattern. Bilateral synchronous testicular tumors with discordant pathology are extremely rare. Only 56 cases have been documented since Bidard first described synchronous testicular tumors with discordant pathology in 1853. To our best knowledge, this study will be the 57th case in the literature.

Ex vivo microscopic testicular sperm extraction at the time of radical orchiectomy in men with nonobstructive azoospermia (NOA): a scoping review

Testicular tumor is the most common solid malignancy in males under 40 years of age. This malignancy is known to have a negative impact on male fertility. Therefore, several techniques for sperm retrieval have been proposed, including microdissection testicular sperm extraction (mTESE). The objective of this study was to review the literature on the outcomes of oncological (Onco)-mTESE at the time of radical orchiectomy. We conducted a comprehensive literature search through PubMed, Scopus, and Cochrane Central Controlled Register of Trials. Only studies reporting ex vivo mTESE in patients with testicular tumor were considered. Twelve papers met the inclusion criteria and were included in this review. Tumor size was identified as the sole preoperative factor influencing spermatogenesis. The considered studies demonstrated a satisfactory success rate for Onco-mTESE, associated with a similarly valid percentage of live healthy births through assisted reproductive technology. Currently, no comparison has been made between Onco-mTESE and conventional Onco-TESE, hence further assessment is required. In cases where the tumor completely replaces the cancer-bearing testicle, a contralateral micro-TESE may be a viable alternative. However, the surgeon should evaluate associated risks and benefits preoperatively. In conclusion, Onco-mTESE at the time of radical orchiectomy appears to be a promising therapeutic option for young patients with testicular tumors. Nevertheless, additional studies are necessary to achieve a definitive conclusion.

Synchronous Bilateral Testicular Tumors With Discordant Histopathology: A Rare Case in an Infertile Male

Testicular cancer, accounting for 1-1.5% of male malignancies, rarely presents bilaterally, with only 2-3% of cases being bilateral and a mere 10% being synchronous, typically sharing histological patterns in both testes. Discordant histological presentation is exceedingly rare, with only a few reported cases. In this report, we detail a case involving a 35-year-old infertile male with bilateral synchronous testicular tumors, each exhibiting different histopathologies. This case highlights the diagnostic intricacies and the necessity for tailored management in the face of such uncommon presentations. The implications of oncological treatment and fertility preservation significantly affect the patient's overall quality of life.

Onco-TESE (Testicular Sperm Extraction): Insights from a Tertiary Center and Comprehensive Literature Analysis

Background and Objectives: The peak of incidence of testicular cancer (TC) occurs among individuals in their reproductive age, emphasizing the importance of fertility preservation as an integral aspect of disease management. Sperm cryopreservation performed before orchiectomy is ineffective in azoospermic men, necessitating alternative approaches such as microdissection testicular sperm extraction (mTESE) at the time of orchiectomy (onco-mTESE) to obtain viable sperm. This study presents the findings from our institution's experience with onco-mTESE and critically discusses our results in light of the existing body of literature. Materials and Methods: This is a tertiary center retrospective analysis of onco-mTESE procedures performed at a single center between December 2011 and July 2022. The included patients were post-puberal men with testicular tumors requiring orchiectomy, along with concomitant severe oligozoospermia or azoospermia. Bilateral mTESE was performed in all cases. Surgical outcomes, sperm retrieval rates, the usage of preserved viable sperm, assistive reproductive techniques' results, and post-operative serum testosterone were recorded. Results: A total of nine patients were included, with a median age of 34 (IQR 29-36) years. All patients had germ cell tumors (GCTs), with seminomatous and non-seminomatous GCTs accounting for 44.4% (n = 4) and 55.6% (n = 5) of patients, respectively. Sperm retrieval occurred in three (33%) patients: one patient in the ipsilateral testis, one in the contralateral testis, and one in both testes. No complications were reported during the procedure, and no post-operative hypogonadism was observed. Among the three patients with successful sperm retrieval, an intracytoplasmic sperm injection (ICSI) was performed in two patients, resulting in two pregnancies, leading to one healthy live birth and one miscarriage. Conclusions: In the context of TC, it is essential to conduct a thorough evaluation of testicular function, including a semen analysis and cryopreservation. Onco-mTESE has proven its safety in preserving fertility in azoospermic cases while ensuring the efficacy of oncological treatment.

Benign cystic Teratoma and Gonadoblastoma developed in bilateral abdominal undescended testis

Cryptorchidism is one of the most common congenital malformations in humans and one of its most important consequences is the development of testicular cancer. While germ cell tumors (GCTs) and sex cord-stromal tumors are major testicular tumors. Gonadoblastoma is a rare neoplasm composed of a combination of germ cells and gonadal stromal elements. In this study we present a patient with bilateral abdominal undescended testis with gonadobelastoma in the left and benign cystic teratoma in the right testicle.

Synchronous Testicular Cancer in Monozygotic Twins

Testicular cancer is the most common neoplasm in men aged 15-45 years old, with several established risk factors such as cryptorchidism, age, and family history. We report a case of a 44-year-old man with a history of cryptorchidism who presented with lesions in his right testis, a large retroperitoneal mass, and diffuse nodal lesions in his lungs. He underwent radical orchiectomy that showed testicular cancer and was immediately inducted into systemic therapy based on bleomycin, etoposide, and cisplatin. Two weeks later, his monozygotic twin brother, also reporting cryptorchidism at a young age, presented with a painless mass in his left testis. He underwent radical orchiectomy that revealed testicular cancer and received adjuvant chemotherapy. The first patient, after two cycles of chemotherapy, suffered from an episode of massive hematochezia and died while his brother remains relapse-free.

Epidemiology of Male Hypogonadism

The epidemiology of male hypogonadism has been understudied. Of the known causes of endogenous androgen deficiency, only Klinefelter syndrome is common with a likely population prevalence of greater than 5:10,000 men (possibly as high as 10-25:10,000). Mild traumatic injury might also be a common cause of androgen deficiency (prevalence 5-10:10,000 men), but large, long-term studies must be completed to confirm this prevalence estimation that might be too high. The classic causes of male androgen deficiency-hyperprolactinemia, pituitary macroadenoma, endogenous Cushing syndrome, and iron overload syndrome-are rare (prevalence < 10,000 men).

Synchronous Bilateral Primary Testicular Tumors With Discordant Histopathology

Concomitant presentation of histologically distinct bilateral testicular tumors is exceedingly rare. Here we report the case of a 20-year-old male who presented with a left testicular mass. He was found to have bilateral testicular masses on ultrasound and underwent bilateral orchiectomy. Left testicular pathology revealed a mixed germ cell tumor consisting of teratoma, seminoma, and germ cell neoplasia in situ; right testicular pathology revealed two foci of pure seminomas. He is currently on active surveillance and remains in remission at 18-month follow-up. Our case demonstrates the rare occurrence of bilateral primary synchronous testicular tumors with different histopathology in each testis. Despite the rarity of this condition, its treatment is based on standard management of unilateral testicular carcinoma, with the added element of prioritization of one tumor over the other. It is important for clinicians to tailor management for bilateral testicular germ cell tumors according to the most aggressive component.
