考虑透明细胞癌
Clear cell adenocarcinoma -
tubular-cystic, or solid; papillary cores have prominent hyalinization; large tumor cells, some with nuclei that protrude into lumina (hobnail), clear cytoplasm (glycogen, mucin, fat); resembles mucinous tumor on frozen section
Positive stains: keratin, hepatocyte nuclear factor 1 beta
Negative stains: AFP, WT1, ER, usually GPC3
DD:
yolk sac tumor (AFP+, GPC3+) ,
Granulosa cell tumor-juvenile (inhibin, calretinin)VS CCC(older patients, diffuse hobnail cells, no follicles, no juvenile granulosa type cells)
