Bilateral abdominal cryptorchidism with large left testicular seminoma and failed right urogenital union

Abstract

This is a case report of a 32-year-old male with bilateral intra-abdominal cryptorchidism. A large seminoma had developed on the left testis with paraaortic lymph nodes metastasis. The tumour was excised easily. The right testis was found just inside the deep inguinal ring, without the vas deferens in the spermatic cord. The patient requested orchidopexy despite the well-explained risk of cancer development. Therefore, a second right groin incision was performed. In the right inguinal canal, there was a normal-looking vas deferens that ended in an atrophic nubbin of fibrous tissue without an epididymis. This is the sixth case in the literature of failed urogenital union resulting in complete separation of testis and vas deferens. The patient underwent orchidopexy and had four cycles of chemotherapy, which led to complete remission of the metastasis. This case highlights the fact that an impalpable undescended testis and finding of blind-end vas deferentia are not enough to establish the diagnosis of vanished testis. The decision to undergo orchiectomy in cases of bilateral cryptorchidism after puberty is also discussed. In our opinion, the choice should be made by the patient after a discussion of the risk for cancer development in the salvaged testis.
