Fig. 24. A 59-year-old male with a painless left testicular mass.

A, B. Transverse gray-scale ultrasonogram shows a predominantly hypochoic lobulated mass in the testicle (A), with increased internal vascularity (B). The patient underwent left orchiectomy and the pathology was consistent with a Leydig cell tumor. C. Macroscopic pathology specimen consisted of the left testicle and spermatic cord. The testicle is bivalved to reveal mass (arrows) measuring 5.0×3.0×2.0 cm with a heterogeneous solid cut surface and areas of hemorrhage and necrosis. The residual testicular parenchyma appears tan-pink and unremarkable.
