BACKGROUND: @entity189 is a rare @entity43 and is thought to be a different histopathologic subtype from hepatoid-type yolk sac @entity5 based upon its pathologic features. However, the cytopathologic characteristics of @entity43 ( @entity43 ) have not been reported previously. We report the clinicopathologic and cytopathologic features and immunoreactivity of a case of @entity43 . CASE: A 36-year-old @entity1 presented to our department with lower @entity490 . @entity43 was found on pelvic examination, magnetic resonance imaging and computed tomography. The @entity5 was diagnosed as a @entity189 of the left ovary based upon the histopathology of the surgically resected specimen. Cytopathologic specimens from a @entity5 touch preparation of the @entity5 exhibited @entity5 cells with abundant cytoplasm. The nuclei contained rough, granular chromatin and large, prominent nucleoli. Several @entity5 cells were multinucleated. @entity5 cells were immunoreactive for @entity160 ( @entity160 ). @entity1710 and @entity1711 staining revealed that the @entity5 cells were in a sinusoidal pattern resembling @entity157 without any glandular formation. The @entity5 cells were negative for @entity1 chorionic gonadotropin while positive for @entity160 , alpha-1-antitripsin, CA-125 and carcinoembryonic antigen. CONCLUSION: Cytopathologic examination is of considerable aid in the diagnosis of @entity43 since cytopathologic preparations highlight the characteristic cell pleomorphism.
