Nonepithelial malignant tumor (NEMT) of the uterine corpus is relatively rare and the prognosis is very poor. In 17 cases of uterine NEMT treated during a period of 14 years, from 1981 to 1994, the correlations between the results of preoperative intracavitary cytologic examination and histopathologic diagnosis, growth pattern of the tumor, surgical stage and symptoms were examined. All cellular samples were obtained from the uterine cavity by the Endocyte technique.<BR>Positive intracavitary smears were seen in eight cases (47.1%) of NEMT, 2/9 cases (22.2%) of leiomyosarcoma (LMS), 1/1 cases of rhabdomyosarcoma, 2/3 cases of high grade endometrial stromal sarcoma and 3/4 cases (75%) of malignant Mallerian mixed tumor (MMT), Though six cases with positive smears were suspected to be NEMT based on cytologic findings, one case was diagnosed only as an unclassified malignant tumor with degeneration, and another case (MMT) was suspected to have poorly differentiated adenocarcinoma.<BR>Five cases of LMS were the intramuscular localized type, all of whom were cytologically negative. The positive rates in surgical stage I and II-IV cases were 36.4%(4/11 cases) and 66.7%(4/6 cases) respectively, and six positive cases were found among 12 cases with genital bleeding, suggesting that the positive rate correlated with surgical stage but not with genital bleeding.<BR>The cytologic findings of MMT were characterized by admixture of carcinomatous cell clusters and single and dyshesive clusters of sarcomatous cells. Sarcomatous cells had ill-defined cytoplasm varying from scanty to abundant and wispy. The nuclei of these cells showed variations in size and shape. The chromatin structure appeared coarsely granular and unevenly distributed. The nucleoli were eosinophilic and prominent in some of the cells.
