Abstract:
Teratomas of the testis in infants are rare tumors which often display immature elements, disturbing in their histologic appearance. Although the presence of similar histologic features worsens prognosis in testicular teratomas in adults and in teratomas of infants and children presenting at other anatomic sites, the presence of immature elements in testicular teratomas of infancy does not appear to affect prognosis. Therefore, orchiectomy alone is adequate therapy for these neoplasms. The case of an 8-month-old infant with a teratoma of testis is presented.

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
