Pure yolk sac tumor of testis in a 50 years old : A rare case report
2016
Yolk sac tumor (YST) is most common in infants and children in age range of 3-8 years in pure form; however in adults, YST rarely occurs in pure form, but commonly occurs in association with other germ cell tumors as mixed forms. Less than 10 adult testicular pure YSTs have been reported in literature. We report a 50-year-old male with testicular neoplasm involving the left testis, with pain following trauma. Alpha-fetoprotein was markedly raised 5726 IU/ml, and on histopathology, characteristic features of YST with abundant Schiller–Duval bodies associated with reticular and microcystic pattern, and focal solid areas of nests and trabeculae of cuboidal cells, with prominent nucleoli and mitotic figures, were noted, and extensive histopathological search did not reveal presence of any other type of tumor.
