## Abstract

Well-differentiated neuroendocrine tumors of the testis are exceedingly rare. Here, we report the case of a 47-year-old male patient complaining of cardiac symptoms with a right testicular mass. A right radical orchiectomy was performed. The histopathological findings showed a well-differentiated neuroendocrine tumor with positive synaptophysin and chromogranin A immunostains.
