We report a case of @entity420 in an 86-year-old woman. Serum AFP was elevated (7824ng/ml) on admission. The surgical specimen obtained by simple hysterectomy and bilateral salpingo-oophorectomy showed an exophytic @entity5 , 10.5cm 6.0cm 3.7cm in size, in the uterine corpus. Microscopically, @entity5 cells proliferated in trabecular or cord-like arrangement, which was considered as "hepatoid appearance". An adenocarcinomatous component was intermingled. The expressions of liver-enriched transcription factors, @entity5456 , @entity4009 , @entity5907 , and CCAAT/enhancer binding protein ( @entity9322 , were investigated in the present case and in 19 cases of @entity4348 (11 cases of Grade 2 and 8 cases of Grade 3), because these nuclear factors are involved in embryonal hepatogenesis. @entity5907 was diffusely positive in the present case, but negative in all cases of @entity4348 . @entity4009 and @entity9322 were positive for the present case and control @entity420 cases ( @entity4009 , 36.8% and @entity9322 , 84.2%). @entity5456 was negative for both the present case and @entity4348 . This is the first report to demonstrate @entity5907 expression in this rare uterine @entity5 .

Primary XXXX of the uterine corpus: A case report with immunohistochemical study for expression of liver-enriched nuclear factors.
