The nuclear DNA content of trophoblasts was measured in 25 cases of normal pregnancy, 46 cases with hydatidiform mole, ten cases with destructive mole and six cases of chorionepithelioma (choriocarcinoma). In normal pregnancy, DNA distribution in syncytiotrophoblasts and cytotrophoblasts showed a sharp peak at the diploid region, although a few cytotrophoblasts with increased DNA content were observed in the first trimester. In chorionepithelioma the DNA content of the trophoblastic cells showed extremely wide distribution without any special peak. In destructive mole, although a wide distribution was observed, the sharp peak was usually noted at the diploid range. Cases with hydatidiform mole were divided into two categories according to the DNA distribution patterns. Type I showed the patterns similar to the first trimester of normal pregnancy and type II resembled the patterns of destructive mole. In hydatidiform mole of type II, subsequent progress towards destructive mole was frequently encountered.

Malignant lymphoma of the uterine cervix. Cytologic diagnosis of a case with immunocytochemical corroboration.

The cytologic findings in a case of primary malignant lymphoma of the uterine cervix initially suggested the presence of a malignant neoplasm. By the use of immunologic methods, the lymphoma cells were shown to possess the nature of B lymphocytes. The need for cytochemical study to make a definitive diagnosis of this rare condition is emphasized. The cytologic findings are compared with those of cytologically similar conditions in the cervix: reticulum-cell sarcoma, chloroma and endometrial stromal sarcoma.

Adenocarcinoma of the uterine cervix metastatic from primary stomach cancer. Cytologic findings in six cases.

The cytologic features of six cases of stomach cancer metastatic to the uterine cervix are presented. Atypical cells were found in cytology samples from four patients. Fewer atypical cells, larger cellular and nuclear areas, more discrete vacuoles, increased frequencies of thickening of the nuclear membrane and more coarsely granular chromatin patterns were the characteristic cytologic findings of metastatic cervical adenocarcinoma as compared with primary endocervical adenocarcinoma.

Cytologic findings of ascites from patients with ovarian dysgerminoma.

The cytomorphologic observations of ascites from three patients with ovarian dysgerminomas are presented. As compared with those in adenocarcinoma, the cytologic findings in this rare malignant ovarian tumor showed more cells lying isolated or in sheetlike arrangements, fewer cells with discrete cytoplasmic vacuoles, less frequent thickening of the nuclear membrane and more frequent multinucleolation.
