1. When vaginal or endometrial cytology is positive and biopsy from the portio or the endometrium is negative, we should suspect the malignancy of the fallopian tube or the ovary. 2. Laparoscopy will be useful to detect the focus, even when we cannot palpate or demonstrate it by ultrasonography or computed tomography. 3. Ultramicroscopic findings, especially ultrastructual alveolar space may be aid of making diagnosis of the eartly malignant lesion of the fallopian tube. 4. The definitions of intraepithelial or early invasive carcinoma of the fallopian tube have not been established. We must be careful in making the diagnosis of intraepithelial or early invasive carcinoma of the fallopian tube, because proliferative and atypical pattern are also demonstrated in some cases of chronic or acute salpingitis and the other lesions. 5. We felt that mitotic activity, nucleolar variability, cribriform pattern and stromal invasion enabled us to make the diagnosis of early invasive carcinoma. 6. Atypical cells of the endometrial aspiration cytology have relatively rich cytoplasm and sheet like arrangement, so we needed the differentiation from repair cells. Hyperchromasia and loss of polarity may be the differential point. Compaired with normal pattern, nuclear and nucleolar enlargement was evident in the touch smear of the operated sample.
