The neoplastic cells are not cohesive. There is an edematous stroma present; lymphocytic infiltrates are rarely seen. Most patients are older males."

Treatment with radiotherapy is highly successful when the tumor is diagnosed in localized stages, which represents the majority of presentations of seminoma."
