case_images: Ultrasound of the right testis,
  longitudinal view. A hypoechoic lesion (arrow) is seen in the posterior testis,
  near the mediastinum testis.

case_images: An ultrasound (Figure 1) revealed an 8 mm x 8 mm x 6 mm intratesticular mass with calcifications.
case_images: Bisected radical orchiectomy
  specimen. The tumor can be seen as a smooth, round, pale lesion (arrow) at the
  mediastinum testis.

case_images: A 0.9 cm well-circumscribed, firm tan-white nodule was identified in the testicular hilum (Figure 2).
case_images: (a) Closer view of gross specimen
  demonstrating discrete white nodule which was firm. (b) A spindle cell
  proliferation was intimately associated with unremarkable ductules within the
  rete testis. (c) Higher power view
  illustrating bland spindled cell proliferation without mitotic activity.
