Testicular germ cell tumor (TGCT) is a most common testicular malignancy with an increasing incidence, and its pathogenesis and mechanisms are not yet clear. The next generation sequencing has become the main tool to uncover the underlying mechanisms of TGCT. The differential gene expressions, gene mutation, predisposing gene-dominated signaling pathways, and changes of the relevant genes in the sex chromosome are largely involved in the occurrence and development of TGCT. Studies on the genomics of TGCT contribute a lot to identifying the pivotal pathogenic genes and paving a theoretical ground for the early screening and targeted therapy of TGCT. This paper summarizes the advances in the studies of the genomics of TGCT so as to reveal thetmechanisms of the disease at the genetic level.

Embryonic-type neuroectodermal tumors (ENTs) arising from testicular germ cell tumors (GCTs) is a relatively common type of somatic transformation in GCTs with poor prognosis and limited therapeutic options, particularly when patients develop disease recurrence or metastasis. Knowledge of key events driving this transformation is limited to the paucity of comprehensive genomic data. We performed a retrospective database search in a CLIA- and CAP-certified laboratory for testicular GCT-derived ENTs that had previously undergone NGS-based comprehensive genomic profiling during the course of clinical care.

(1) Background: Testicular cancer, although accounting for only 0.5% to 1% of all solid male cancers, is the most common malignancy in males aged 15 to 35 years. Non-seminomatous germ cell tumors (NSGCT) represent nearly half of all testicular germ cell tumors and are associated with a more aggressive clinical course.

Androgen secretion by testicular germ-cell tumors (GCTs) appears to be markedly rare and likely underreported in the literature. This case study highlights a patient with such a rare tumor, underscoring a notable and yet easily avoidable diagnostic oversight in one of the most prevalent cancers among men. We advocate for increased vigilance and the inclusion of specific symptomatic screening for hyperandrogenism of select patients in existing guidelines and, where appropriate, the implementation of standardized hormonal laboratory analyses in both pre- and post-orchidectomy assessments.

Spermatogonial stem cells (SSCs) form haploid gametes through the precisely regulated process of spermatogenesis. Within the testis, SSCs undergo self-renewal through mitosis, differentiation, and then enter meiosis to generate mature spermatids. This study utilized single-cell RNA sequencing on 26,888 testicular cells obtained from five Holstein bull testes, revealing the presence of five distinct germ cell types and eight somatic cell types in cattle testes.

Germ cell tumors, the most common of the testicular neoplasms, originate from primordial germ cells. These tumors are known for their totipotent nature, capable of differentiating into various cell types. This case report presents a rare occurrence of mucinous cystadenoma in a patient who received chemotherapy for metastatic left non-seminomatous germ cell tumor (NSGCT) of the testis.
