| Abstract: | The accuracy of endometrial aspiration smears obtained with the Isaacs cell sampler in the diagnosis of malignant mixed mesodermal tumors (MMMT) was compared to the results obtained with routine cervical and vaginal smears in five cases of MMMT found in a series of 220 endometrial aspirations. Cervical and vaginal smears previously taken on these patients were positive for adenocarcinoma or MMMT in two cases and suspicious for adenocarcinoma in the remaining three cases. Endometrial aspirates were positive for MMMT in three cases and positive for adenocarcinoma or MMMT in two cases. The endometrial aspiration smears contained a variety of cells: malignant glandular, squamous, spindly stromal, undifferentiated, osteoid and tumor giant cells; chondrocytes and free psammoma bodies were also observed. These cases indicated that endometrial aspiration can accurately detect the heterologous cellular elements found in MMMT and is an effective technique in its diagnosis. |
