Findings

No curated finding names testicular seminoma yet. Everything below is reference data from Mondo, HPO and GenCC, not evidence about what affects it.

Definition

A malignant germ cell tumor arising from the testis. It is believed that it is derived from the sexually undifferentiated embryonic gonad. Treatment with radiotherapy is highly successful when the tumor is diagnosed in localized stages, which represents the majority of presentations of seminoma.
