The cytologic findings in two cases of stromal sarcoma of the uterus

The cytologic findings in two cases of stromal sarcoma of the uterus are presented. The morphologic features useful in the cytologic diagnosis of this neoplasm are discussed, including: (1) the presence of isolated tumor cells; (2) the uniform pattern of tumor cells in spite of marked nuclear variations; (3) the "comet" appearance of some tumor cells; and (4) the presence of bizarre, multinucleated, giant tumor cells.
