Non-germ cell testicular tumors are rarely seen. Sex-cord stromal tumors, which make up the majority of testicular tumors other than germ cell tumors, share common immunohistochemical and histomorphological features. Our aim in presenting this case is to define the Sertoli cell nodule (SCN), which is one of the relatively rare primary testicular pathologies that can be detected in half of adult undescended testes, with its histomorphological and immunohistochemical features, and to make its differential diagnosis.
