Clinicopathological Study of Regressed Testicular Tumors (Apparent Extragonadal Germ Cell Neoplasms)

Abstract

Spontaneous regression of a germ cell testicular tumor should be considered in each patient with extragonadal germ cell neoplasms. Ultrasound diagnosis of and surgical treatment for these primary testicular tumors appear critical to prevent relapse because residual disease develops in a significant proportion of cases.
