Long-Term Follow-Up of Testicular Microlithiasis in Children and Adolescents: Multicenter Prospective Cohort Study of the Italian Society of Pediatric Urology
Conclusion TM is a controversial entity, often associated with several inguinogenital features, which rarely can recover. Testicular malignancy, although present in TM, has not proven definitively associated to microliths. Proper counseling, yearly ultrasound, and self-examination are long-term recommended.[...]Georg Thieme Verlag KG Stuttgart · New YorkArticle in Thieme eJournals:Table of contents | Abstract | Full text
Conclusions KLHL11-abs associate with a spectrum of syndromes and tumors wider than those previously reported; 44% of patients have concurrent neuronal antibodies, some of them (anti-NMDAR) pathogenically relevant. Brain immunostaining is not useful for routine screening of KLHL11-abs.
Conclusions: Immune infiltrate/checkpoints associate with patients’ outcome, constituting novel (potentially targetable) disease biomarkers.
In conclusion, TCF7L1, highly expressed in non-seminomatous testicular germ cell tumors, might be used as a marker for diagnosis of testicular germ cell tumors, two therapeutically different entities, for better patient management. PMID: 31381875 [PubMed - as supplied by publisher]
AbstractTesticular germ cell tumors are the most frequent malignancies found in men between 15 and 44 years old. Although cellular apoptosis susceptibility (CAS) was demonstrated to be upregulated in breast cancer and colon cancer, the expression of CAS in the human testis and testicular germ cell tumors remained elusive. In the present study, CAS-positive signals were detected in the normal testi cular tissues, cancer adjacent normal testicular tissues, seminoma, yolk sac tumor, and teratoma. Interestingly, the expression level of CAS in testicular germ cell tumors (TGCTs) (but not seminoma) was significantly lower ...
In this study, we generated TCam-2 cells double-deficient for SOX2 and FOXA2 using the CRISPR/Cas9 technique and xenografted those cells into the flank of nude mice. Upon loss of SOX2 and FOXA2, TCam-2 maintained a seminoma cell fate for at least twelve weeks, demonstrating that both factors are key players in the reprogramming to an EC-like cell fate. Therefore, our study adds an important piece to the puzzle of GCT development and plasticity, providing interesting insights in what can be expected in a patient, when GCT cells are confronted with different microenvironments.
Abstract In 2016, the WHO classification of testicular germ cell tumors was revised considering advances in the understanding of their tumorigenesis and molecular features. This restructuring led to a division into two major groups with, on one hand, prepubertal-type tumors, not derived from germ cell neoplasia in situ (GCNIS), and on the other hand, postpubertal-type tumors, GCNIS-derived, which occur in youg men (seminoma and non seminomatous germ cell tumors - embryonal carcinoma, yolk sac tumor, teratoma and choriocarcinoma essentially). The term germ cell neoplasia in situ is consensually accepted as a new te...
Aditya Pratap Singh, Ramesh Tanger, Deepika Mishra, Maryem Ansari, Arun Kumar Gupta, Arvind Kumar ShuklaJournal of Indian Association of Pediatric Surgeons 2019 24(2):144-146 Testicular tumors are rare in children but highly treatable and usually curable. Seminomas are extremely rare in prepubertal children. Among nonseminomatous germ cell tumors, the most common are teratomas and yolk sac tumors. Mixed germ cell tumor (MGCT) contains more than one germ cell component. MGCT is very rare in prepubertal age group. Here, we are presenting a case of MGCT in a newborn child with a review of literature. It is the first reported...
CONCLUSION:: Primary neuroendocrine carcinoma of the testis is a very rare malignant tumor. Immunohistochemistry contributes to its diagnosis in relation to other metastatic neuroendocrine carcinomas, carcinoid tumor teratomas, seminoma, and Sertoli cells.

In conclusion, neuroglial differentiation and neoplasms are rare in testicular germ cell tumors and are most commonly associated with teratomas; they can be seen in primary and metastatic sites. They exhibit the full range of neuroglial differentiation including developing CNS to gliomas/glioneuronal tumors WHO grades I-IV. None of the cases showed results consistent with ATRX, IDH or BRAF alterations, suggesting they have different oncogenic mechanisms than their CNS counterparts.
CONCLUSION: Finally, the pathogenesis of testicular germ cell tumor needs to be deeply understood so that it will improve data on stem cells, tumorigenesis and disease tumor management by more selective treatment. PMID: 30636617 [PubMed - as supplied by publisher]
