A man in his early 50s underwent radical orchiectomy due to a 5.5 cm solid mass in the left testis and a partial orchiectomy for a 1.2 cm solid mass in the right testis. The left testicular mass is shown in figures 1 (gross), 2, 3 and 5. Figure 4 shows the tumor in the right testis, and its transition from a solid mass to areas of intratubular growth (which were absent in the larger mass).
