A histological review of radical orchiectomy specimens was performed to assess the impact of testicular cancer on spermatogenesis. Slides from 28 patients with testicular cancer were available for review, consisting of 14 pure seminomas, 12 embryonal carcinomas and 2 mixed tumors. For each specimen tubules adjacent (less than 3 mm.) to the tumor and distant (more than 3 mm.) from the tumor were evaluated. This study indicates that marked impairment of ipsilateral spermatogenesis is associated with testicular carcinoma, particularly in the vicinity of the tumor. The quality of distant spermatogenesis appears to be influenced by tumor type and not by elevation of known serum tumor markers, such as human chorionic gonadotropin and alpha-fetoprotein, nor by the presence of carcinoma in situ.

Ex Vivo Fluorescence Confocal Microscopy Meets Innovation and Revolutionary Technology, for "Real-Time" Histological Evaluation, in Pediatric Surgical Oncology.

Background And Aim: Ex vivo fluorescence confocal microscopy (FCM) systems are innovative optical imaging tools that create virtual high-resolution histological images without any standard tissue processing, either freezing or fixing in formalin and embedding in paraffin. These systems have opened an era that would revolutionize pathological examination by providing rapid, real-time assessments across various pathology subspecialties, potentially replacing conventional methods that are tissue- and time-consuming. This study aimed to present the first utilization of FCM in pediatric surgical oncology, focusing on assessing the benefits, particularly in facilitating rapid and accurate diagnosis.

Background/objectives: Testicular germ cell tumors (TGCT) are common in young adult men and have high cure rates. Conventional serum tumor markers and imaging are not able to differentiate between histologic subtypes of the disease, which portend different prognoses and require distinct therapeutic strategies. Micro-RNAs (miRNAs) are small non-coding transcripts involved in the post-transcriptional regulation of gene expression, which have emerged as promising biomarkers in a variety of tumors.

Genitourinary (GU) malignancies are common and associated with significant morbidity and mortality. In patients with localized GU cancers, surgical resection or definitive radiation remain the mainstays of treatment. Despite definitive treatment, many patients with high-risk localized disease experience recurrence.

Introduction: Choroidal metastases from systemic malignancies are the most common intraocular malignancies in adults. External beam radiation (EBR) has historically been first-line therapy for metastatic tumors to the choroid. However, good responses have been described with newer targeted biologics.

Rhabdoid differentiation is an indicator of poor prognosis that is often seen in renal cell carcinoma; however, it is also rarely seen in non-renal tumours. Therefore, pathologists should carefully review this finding and report. This report describes the first case of a seminoma of testicular origin that developed rhabdoid differentiation.
