ABSTRACT

BACKGROUND:

Although oncologic testicular sperm extraction (onco-TESE) has been increasingly practiced, the evidence of onco-TESE performed in patients with testicular cancer is insufficient. Furthermore, in bilateral testicular cancer, accounting for 0.5%-1% of testicular cancers, onco-TESE is more challenging and has been insufficiently reported. CASE PRESENTATION Here we report the case of a 25-year-old man who underwent onco-TESE from his residual single testis with a nonseminomatous germ cell tumor that occurred 5 years after orchiectomy of the contralateral testis. A second orchiectomy and simultaneous TESE from the noncancerous testicular tissue were performed. The pathological diagnosis was germ cell tumors, tumors of more than one histological type (embryonal carcinoma, immature teratoma, yolk sac tumor, seminoma, and choriocarcinoma; pT1N0M0). The patient subsequently married and hoped for fatherhood 3 years later. Whereas histological diagnosis of the normal testicular tissue was Johnsen score 6 (maturation arrest), morphologically normal and motile sperms were successfully retrieved from thawed TESE samples and used for multiple cycles of intracytoplasmic sperm injection. Although the conception has not been succeeded to date, ICSI attempts have been continuing.

CONCLUSION:

This case demonstrates the effectiveness of onco-TESE for challenging cases such as bilateral and nonseminmatous testicular cancer.
CONTEXTE Bien que l'extraction oncologique de spermatozoïdes testiculaires (onco-TESE) soit une pratique croissante, le bien-fondé de réaliser une onco-TESE chez des patients qui ont un cancer du testicule reste insuffisamment étayé. Par ailleurs, en cas de cancer bilatéral, qui représente 0,5­1% des cancers du testicule, l'onco-TESE est. plus difficile, et peu de cas ont été rapportés. CAS CLINIQUE Nous rapportons le cas d'un homme de 25 ans qui a bénéficié d'une onco-TESE pour tumeur à cellules germinales non séminomateuse sur testicule unique résiduel, survenant 5 ans après une orchidectomie controlatérale. Ont été réalisées simultanément une seconde orchidectomie et une TESE sur tissu testiculaire non tumoral. L'étude anatomopathologique a montré des tumeurs à cellules germinales de plus d'un type histologique (carcinome embryonnaire, tératome immature, tumeur vitelline, séminome, et choriocarcinome; pT1N0M0). Le patient a ensuite convolé en noces et le couple a souhaité avoir un enfant 3 ans plus tard. Alors que l'étude histologique du tissu testiculaire normal donnait un score de Johnsen à 6 (arrêt de maturation), des spermatozoïdes morphologiquement normaux et mobiles ont été retrouvés dans les échantillons de TESE décongelés; ces spermatozoïdes ont été utilisés pour réaliser plusieurs cycles d'injection intra cytoplasmique. Bien qu'aucune conception n'ait eu lieu à ce jour, les tentatives d'ICSI se poursuivent.

CONCLUSIONS:

Ce cas montre l'efficacité de l'onco-TESE face à des cas tels qu'un cancer testiculaire bilatéral et non séminomateux.
