Mixed germ cell tumors represent 40-60% of testicular tumors, they can occur in undescended testicles or not, and Extratesticular sites. They are associated with conditions such as cryptorchidism, testicular atrophy and inguinal hernia. They may present with symptoms including unilateral scrotal volume increase, with or without pain. Microscopically various combinations of components observed histological germ is indispensable determining the percentage of each, and measurement of tumor markers for prognostic implications. Treatment is based on surgical resection plus chemotherapy and / or adjuvant radiotherapy. In treated patients, survival is good, even in advanced stages of the disease. Male 20 years presents with sudden onset of pain and sensation of mass in the right testicle. Ultrasound reveals solid lesion that compromises testicular parenchyma. Radical orchiectomy is done. Pathological study shows malignant tumor with solid and cystic areas, with mixed germ cell tumor type component of embryonic carcinoma, teratoma, endodermal sinus tumor and without seminoma component.
