In the present report, we discuss an extremely rare case of adult-onset MGCT composed mainly of yolk sac tumor (YST) around the pineal gland. Case description: A year-old Japanese man presented with disturbance of consciousness, Parinaud's syndrome, and gait disturbance. Magnetic resonance imaging revealed a pineal mass lesion, and subtotal resection of the tumor was achieved. Tumors arising from the yolk sac; Choriocarcinoma. Embryonic tumors Extraembryonic tumors. This histological classification reflects the degree of differentiation that the cells have reached before they degenerate malignantly. This can happen to the cells at the following stages: In an adult woman.
Primary yolk sac tumor of the liver is extremely rare in adults. We report a case of a young man with an unresectable primary yolk sac tumor of the liver, who had a platinum-refractory disease that progressed despite 2 lines of chemotherapy. We review the literature pertaining to primary yolk sac tumor of the liver and its management. Yolk sac tumor (YST) is most common in infants and children in age range of 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.
