Cytology of yolk-sac tumor of the ovary in ascitic fluid. Report of a case

Abstract

The cytologic, serologic, immunocytochemical and histologic findings of a yolk-sac tumor of the ovary in which the diagnosis was suggested by the cytologic examination of ascitic fluid specimens are reported. The case emphasizes the importance of evaluating, in addition to smears, the cytologic findings of a cell block specimen (which is generally prepared from an effusion) to obtain more diagnostic clues. A preliminary cytomorphologic diagnosis of this highly malignant tumor is valuable as a guide in planning further immunocytochemical and serologic studies.
