Testicular Tumors: A Contemporary Update on Morphologic, Immunohistochemical and Molecular Features.

Adv Anat Pathol 2021 Jul;28(4):258-275

Department of Pathology & Laboratory Medicine, Indiana University School of Medicine, Indianapolis, IN.

Testicular tumors are incredibly diverse and one of the most challenging areas in surgical pathology. Because of the rarity and overlapping features with numerous entities occurring in the testis and paratestis, these tumors pose a diagnostic challenge even to the most experienced general pathologists. In 2016, the latest "World Health Organization (WHO) classification of testicular tumors" was released, which incorporated several updates to the previous 2004 classification system. Read More

Testicular and paratesticular tumors and tumor-like lesions in the first 2 decades.

Semin Diagn Pathol 2014 Sep 15;31(5):323-81. Epub 2014 Jul 15.

The James Homer Wright Pathology Laboratories, Massachusetts General Hospital, Harvard Medical School, Boston, Massachusetts.

The spectrum of testicular tumors and tumor-like lesions that affect young patients (defined for purposes of this article as less than 20 years old) differs significantly from that in an older age group. Although germ cell tumors remain the single largest category, they are a smaller proportion than in adults. Furthermore the pathogenesis and behavior of comparably named germ cell tumors differ depending on whether or not they have developed in prepubertal or postpubertal patients. Read More

Testicular and paratesticular tumours in the prepubertal population.

Lancet Oncol 2010 May;11(5):476-83

Division of Surgery and Interventional Sciences, University College London and UCH/UCL Comprehensive Biomedical Research Centre, London, UK.

Prepubertal testicular and paratesticular tumours are a rare group of tumours, distinct from postpubertal paediatric and adult tumours of this region. Tumours within this group are testicular germ-cell tumours (such as benign teratoma, epidermoid cyst and malignant yolk-sac tumours) and stromal tumours (such as juvenile granulosa-cell, Leydig-cell, and Sertoli-cell tumours). Paratesticular tumours can be benign (lipoma, leiomyoma, haemangioma) or malignant (rhabdomyosarcoma, melanotic neuroectodermal tumour of infancy). Read More

Prepubertal testis tumors: actual prevalence rate of histological types.

J Urol 2004 Dec;172(6 Pt 1):2370-2

Department of Urology, Children's National Medical Center, Washington, DC, USA.

Purpose: Tumor registries, urological textbooks and literature surveys all assert that yolk sac tumors are the most common primary testicular tumors in boys 12 years and younger. In contrast, several individual institutions have reported that benign tumors are more common than malignant tumors. To clarify these discordant findings, we surveyed the primary pathology records from 4 major pediatric centers. Read More

Pediatric urologic oncology: bladder, prostate, testis.

Urol Clin North Am 2004 Aug;31(3):619-27, xi

University of Pittsburgh and Department of Urology, Children's Hospital of Pittsburgh, 4A-424 Desoto Wing, 3705 5th Avenue, Pittsburgh, PA 15213, USA.

Although treatment for bladder, prostate, and testis cancer comprises a large part of adult urologic practice, the tumors that affect these organs in children are rare. Rhabdomyosarcoma,which affects the bladder, prostate, vaginal, and paratesticular areas,is treated with a combination of surgery, chemotherapy, and radiation. Most transitional cell carcinomas of the bladder and prepubertal testis tumors are managed surgically owing to the low stage at presentation. Read More
