Three testicular tumor types are recognized. Non expansive scrotal Interstitial Cell Tumors (benign), expansive testicular Seminomas (benign and malignant forms) and retained Seritoli Cell Tumors. Seritoli cell tumors often have a feminizing syndrome associated with their development. Interstitual Cell Tumors are associated with testosterone but do not have a dramatic clinical presentation to their presence. Most are often found by incidental physical examination.
