Transformation of an AFP-positive yolk sac carcinoma
into an AFP-negative neoplasm: evidence for in vivo cloning of the human parietal yolk sac carcinoma
Yolk sac carcinoma
(endodermal sinus tumor): ultrastructure and histogenesis of gonadal and extragonadal tumors in comparison with normal human yolk sac.
And in the ones with original liver HAC metastasis, other cancerous changes such as original HCC, hepatoblastoma, and germ cell tumors (especially yolk sac carcinoma
), in addition the rare case of papillary or tubular gastric carcinoma type with higher serum AFP, should be ruled out .
The first patients in the registry include 17 survivors of lymphoma, 8 survivors of sarcoma, 5 survivors of Wilm's tumor, 4 survivors of neuroblastoma, and 1 survivor each of hepatoblastoma, ovarian germ cell tumor, yolk sac carcinoma
, and Triton tumor.
