Cytologic findings of ascites from patients with ovarian dysgerminoma

The cytomorphologic observations of ascites from three patients with ovarian dysgerminomas are presented. As compared with those in adenocarcinoma, the cytologic findings in this rare malignant ovarian tumor showed more cells lying isolated or in sheetlike arrangements, fewer cells with discrete cytoplasmic vacuoles, less frequent thickening of the nuclear membrane and more frequent multinucleolation.
