Solid pseudopapillary tumor: a new tumor entity in the testis?

We greatly appreciated the case by Michal et al [1] reporting on a pancreatic analogue solid pseudopapillary tumor (SPT) of the paratesticular location. Analogously, we recently dealt with 2 cases arising in the right testis of a 60-year-old man and in the left testis of a 56-year-old man. The patients have an uneventful medical history, and the testicular nodules (1.5 and 3.2 cm, respectively) were incidentally disclosed during an ultrasound echosonography performed for hydrocele. Routine laboratory test results and serum tumor markers were unremarkable.
