Two kinds of endometrial neoplasia arising from different origins in the uterine corpus: comparison of p53 expression and sex steroid receptor status.

This study presents a case of endometrial clear cell adenocarcinoma complicated by complex atypical glandular hyperplasia surrounded by adenomyosis in the uterine myometrium. The former was immuno-negative for estrogen receptor (ER) and positive for p53, whereas both of the latter were immuno-positive for ER and negative for p53. Therefore, there were two kinds of neoplasia arising from different origins in the uterine corpus.

Thyroid function in early pregnancy in Japanese healthy women: relation to urinary iodine excretion, emesis, and fetal and child development.

CONTEXT: The effect of constant rich iodine intake, especially during pregnancy, has not been well understood. OBJECTIVE: The objective was to examine urinary iodine excretion and thyroid function in early pregnancy in Japanese healthy women. We also studied fetal maturation and child development in these women. DESIGN AND SETTING: This study was an observational, prospective study conducted at a maternity hospital. SUBJECTS: Subjects were 622 pregnant women who visited a maternity hospital consecutively in early gestation. Subjects with positive thyroid antibodies were excluded, and finally 514 subjects were examined. Offspring subjects were infants born to the maternal subjects. MAIN OUTCOME MEASURES: Thyroid function, serum thyroperoxidase antibodies, and urinary concentrations of iodine were measured at the initial obstetrical visit. The fetal maturation scores estimated by the Dubowitz and Ballard methods in newly born infants were assessed. A child developmental test was performed using the Enjoji Scale up to 12 months of age. RESULTS: The distribution of urinary iodine concentrations was large, and the average was extremely high. There were significant positive correlations between urinary iodine and serum TSH (r = 0.1326; P < 0.005). Serum TSH during early pregnancy in mothers had no relevance to parameters in neonates, scores of fetal maturation, or child developmental testing in their infants. CONCLUSIONS: Iodine excess during early pregnancy seems to have no adverse effects on the fetus in healthy Japanese women. To avoid hypothyroidism, reducing excess dietary iodine intake to moderate intake may be beneficial for pregnant woman in Japan.

The relationship between endometrial carcinoma and coexistent adenomyosis uteri, endometriosis externa and myoma uteri.

The relationship between endometrial carcinoma and coexistent adenomyosis uteri, endometriosis externa and myoma uteri has been reported in only a few studies. We studied the characteristics of the endometrial carcinomas accompanied by these benign diseases. The total number of endometrial carcinoma cases was 179, consisting of 29 (16%) endometrial carcinomas with adenomyosis uteri, 12 (7%) with endometriosis externa, 51 (28%) with myoma uteri, and 87 controls (49%) without these benign diseases. Seventy-nine, 75, and 65% of the endometrial carcinomas with adenomyosis uteri, endometriosis externa and myoma uteri, respectively, showed a low histologic grade (G1). In particular, the patients with adenomyosis uteri and endometriosis externa were relatively younger than the control patients (54.2, 54.1 years old versus 57.7 years old). Furthermore, these patients were all treated at stage 1 and had a good prognosis. In brief, there are some clinicopathologic differences between the endometrial carcinoma cases with benign hormone-dependent disease and the cases without these disease.
