Morphofunctional findings in adenocarcinoma of endometrium.

Ten cases of adenocarcinoma of the endometrium were studied using histochemical methods for mucopolysaccharides and immunocytochemical methods for the localization of various markers, such as EMA (epithelial membrane antigen), GCDFP-15 (gross cystic disease fluid protein) and CEA. Four cases appeared to contain High Iron Diamine-positive substance and 6 cases were positive using an immunocytochemical method with a polyclonal anti-CEA antiserum. In contrast, no cases stained when a monoclonal anti-CEA antiserum was employed. This suggested that HID- positive material could be a sign of differentiation towards cells with a secretory function.

Morpho-functional changes in normal cyclic endometrium.

Eight cases of normal endometrium in the early proliferative phase and an equal number of cases in the late secretive phase were stained histochemically for acidic mucosubstances and immunocytochemically for epithelial membrane antigen (EMA), carcinoembryogenetic antigen (CEA) and Gross Cyst Disease Fluid Protein -15 (GCDFP-15) production. Alcian blue positive material was observed in both phases of the cycle, although the distribution was different. Sulphated mucosubstances were only present in the secretive phase. No CEA nor GCDFP-15 immunoreactive material was detected. EMA positive staining was observed in all cases, but the distribution varied according to the two different phases of the cycle.

Sclerosing stromal tumor of the ovary. A hormonal, histochemical and ultrastructural study.

Three new cases of sclerosing stromal tumor of the ovary have been studied by hormonal, immunohistochemical and electron microscopic analysis. The results confirm that this tumor may have hormonal activity. Ultrastructural study shows findings different from those previously reported. The authors propose an origin from the ovarian stroma with luteinization of stromal tumor cells.

Behavior of some steroids in endometrial adenomatous and atypical hyperplasia.

Endometrial adenomatous and atypical hyperplasia are the histopathological pictures that more frequently may develop into an adenocarcinoma. It is believed that a hormonal action may favour the genesis of endometrial cancer. We studied the plasmatic levels of some steroids, considered to be responsible for neoplastic changes, in patients with adenomatous and atypical hyperplasia. With this object we measured plasmatic levels of estrone, estradiol, androstenedione, DHEA-S and testosterone in postmenopausal patients with adenomatous and atypical hyperplasia and in fertile women, both in proliferative and secretory phases. We didn't find any difference in the steroid pattern in the two groups.

Behaviour of some steroids in postmenopausal women with coelomic ovarian tumors.

In order to study the hormonal pattern in ten postmenopausal women with coelomic ovarian tumors we measured Estrone, Androstenedione, DHEA-S and Testosterone plasmatic levels before and after surgery. Estrone and Androstenedione plasmatic levels were significantly higher in patients with coelomic ovarian tumors than in the control group and they showed a rapid and constant decrease after surgery. Nevertheless we didn't find any ovarian histological picture to explain the hormonal increase.
