Abstract:
Testicular tumors occur in 0.5 to 2 per 100,000 children. They are 1-2% of all solid tumors before puberty. The clinical history, testicular and abdominal ultrasonography, alpha-fetoprotein and human chorionic gonadotropin, estrogens and androgen levels, FSH and LH determine the diagnosis. The pathology determines the specific cell. We report seven cases, three germ cell tumors: a Yolk sac tumor in a child of 18 months and two mature teratomas in children between 2 and 11 years presenting as a painless testicular mass without other symptoms. Three tumors estrumales: one derived from Leydig cells and two of the granulosa cells, a palpable testicular mass was added precocious puberty in stage II-III of Tanner in the first, second gynecomastia in Tanner stage III and the third only with testicular mass. The seventh case, Lipoma para-testicular mass palpable. The treatment was radical orchiectomy in five cases. Testis-sparing surgery in Leydig cell tumor and resection of the paratesticular mass was performed through scrotal. The Yolk sac tumor requiring chemotherapy with good outcome. Retroperitoneal lymph node dissection is not recommended in prepubertal. Historically prepubertal testicular tumors have been treated in adults. Recent testicular preservation algorithms optimize and minimize the morbidity of adjuvant therapies. Many are benign and can be treated with preservation of the testis. Localized malignant tumors can be treated by orchiectomy.
