I'm not sure if you are describing a mass within the scrotum, or a mass above the scrotum (i.e., in the groin). In any case, most such masses are benign, and can include hernias, hydroceles, and cysts, among other lesions. Testicular masses should always be further evaluated, however, to rule out the possibility of testicular cancer.
