A cytomorphological study of malignant cells in the ascites of ovarian cancer was made. Cytological specimens were obtained from the patients with ovarian carcinoma at the operation. The results of this study are as follows.
1. The shape and size of cellular clusters were helpful in identifying the histopathologic patterns to some degree.
2. In serous cystadenocarcinoma, isolated and scattered malignant cells or cellular clusters of various sizes were frequent, and cellular clusters mostly appeared like muscats. The presence of cilia or psamomma bodies in ascites strongly suggested that the primary site was serous cystadenocarcinoma of the ovary.
3. In Krukenberg tumors, malignant signet ring cells were found occasionally. Generally, cytoplasmas were scanty in Krukenberg tumors, but abundant in mucinous cystadenocarcinoma.
4. PAS staining was not helpful in identifying the tumor type.
