An immunohistochemical study of 15 ovarian @entity406 -fixed, @entity982 -embedded @entity5000 showed positive staining of @entity5 cells for @entity2277 in all cases. @entity5000 stained for @entity2873 . @entity2283 positivity of @entity5 cells was detected in four @entity5000 . Glial fibrillary acidic protein was present in two @entity5 . Prominent @entity1 beta chorionic gonadotropin staining was seen in one @entity5 . S-100 protein was found in two and carcinoembryonic antigen in one of the @entity5000 . Placental alkaline phosphatase was present in 12 of the 15 @entity5 studied. The heterogeneity of the cytoskeletal profile and of other markers showed some similarities to our previously published results on @entity4797 . Thus, in contrast to previous concepts, @entity5000 , as is the case with its testicular counterpart the @entity4797 , appears to be capable of further differentiation, albeit at a primitive level. Our observations also may help to elucidate the relationship between @entity5000 and other nondysgerminomatous @entity43 , and may be of help in the differential diagnosis with poorly differentiated @entity43 , or other germ cell @entity5 .
