title: Unusual presentation on the right side of ectopic testicular spleen.
abstract: An unusual case of right-side testicular spleen is presented. Although described as early as 1889, all cases except one were described to have occurred on the left side. This report documents a second case of extra-testicular spleen occurring on the right side. Since ectopic spleen is an extra-testicular mass and invariably benign, it must be recognized and considered in the primary differential diagnosis of any intrascrotal mass. Since ectopic intrascrotal spleen occurs in the majority of clinical cases under 20 years of age, a preoperative diagnosis of ectopic spleen will prevent possibly unnecessary radical testiculectomy in this age group. Radioactive sulphur colloid will localize in the ectopic spleen, and therefore this modality can be used as an additional preoperative diagnostic tool. Since ectopic testicular spleen was found in up to 25% of all reported cases during orchiopexy and/or herniorrhaphy repair, this entity must be familiar to general and urological surgeons.
