The [[pathophysiology]] of testicular cancer depends on the [[histological]] cell subtypes and findings. Most testicular cancers derived from the lack of differentiation of [[Primordial germ cells|primordial]] [[germ cell]] into [[spermatogonia]]. [[Germ cells]] testicular tumor have some [[genetic]] component while most sex [[Stromal|cord stromal]] testicular cancer have are [[hormonal]] dependent. Most gross [[pathology]] of testicular tumors look similar on the physical appearance. On [[microscopic]] [[histopathological]] analysis of testicular cancer, fried-egg appearance is the characteristic finding of [[seminoma]]; marked [[nuclear]] [[atypia]] is the characteristic finding of [[embryonal carcinoma]]; hyaline-type globules, and Schiller-Duval bodies are characteristic findings of [[yolk sac tumor ]] ; syncytiotrophoblasts and [[cytotrophoblast]] cells are the characteristic findings of [[choriocarcinoma]], [[Polymorphism]] with"spirene" [[chromatin]] for spermatocytic.

Overview

The pathophysiology of testicular cancer depends on the histological cell subtypes and findings. Most testicular cancers derived from the lack of differentiation of primordial germ cell into spermatogonia. Germ cells testicular tumor have some genetic component while most sex cord stromal testicular cancer are hormonal dependent. Most gross pathology of testicular tumors look similar on the physical appearance. On microscopic histopathological analysis of testicular cancer, fried-egg appearance is the characteristic finding of seminoma; marked nuclear atypia is the characteristic finding of embryonal carcinoma; hyaline-type globules, and Schiller-Duval bodies are characteristic findings of yolk sac tumor  ; syncytiotrophoblasts and cytotrophoblast cells are the characteristic findings of choriocarcinoma, Polymorphism with"spirene" chromatin for spermatocytic.
