The right testicular parenchyma (a) is effaced by a neoplastic proliferation of Leydig cells with multifocal scattered microhaemorrhages (arrows). The right testicular parenchyma (a) is effaced by a neoplastic proliferation of Leydig cells with multifocal scattered microhaemorrhages (arrows). The mitotic index is low with 1–2 mitoses per high power field. The left testicular parenchyma (b) is characterised by an intratubular proliferation of neoplastic Sertoli cells showing moderate features of atypia (arrows) and surrounded by abundant fibrovascular stroma.
