[Clinical, hormonal and histological features in ovarian stromal hyperthecosis].

The aim of our study was to investigate clinical, hormonal and histological features of ovarian stromal hyperthecosis We have studied 104 patients with a histological diagnosis of ovarian stromal hyperthecosis and hyperplasia. Analyzing the results we can conclude that clinical features of ovarian stromal hyperthecosis and hyperplasia with polycystic ovarian disease and without it were identical and characterised by virilization syndrome, disorders of menstrual cycle and reproductive function; metabolic and vegeto-vascular disorders; breast and endometrial hyperplasias, high blood level of testosterone . The histological study of ovarian stromal hyperthecosis has showed that superficial part of ovarian cortex is hypocellular and fibrotic, contains scattered follicles with few granulosa cells, luteinized internal theca cells, hyperplasia of deep cortex and medulla, corpus luteus is absent.

Meigs' syndrome. A case report.

A case of Meig's syndrome is reported and the rarity of this condition is emphasised. The need for exploratory laparotomy in patients with solid ovarian tumours associated with ascites and pleural effusion, and free of malignant cells, is stressed.

[Hyperplastic processes and endometrial cancer in patients with hormone-producing ovarian tumors].

Status of the endometrium was assessed in 357 patients with hormone-producing tumors of the ovaries of major histological types such as theca cell (161 cases), granulosa cell (123) and mixed theca-granulosa cell tumors (22) as well as androblastoma (23) and Brenner's tumor (28 patients). Hyperplastic lesions of the endometrium, cancer included, were established in 250 (74.8%) patients with feminizing hormone-producing tumors whereas androblastoma patients showed either atrophic or normal endometrium (78.3% cases) and failed to reveal atypical hyperplasia or cancer of that site.

[Serum estradiol as a marker in recurrent granulosa-theca-cell tumor].

A case of a granulosa-theca-cell tumour of the ovary in a 39-year-old woman is reported. Despite benign histology and apparently radical operation, tumor growth relapsed twice before apparent cure. Oestradiol in serum proves valuable as a tumour marker and correlates well with tumour relapse.

Serum 17 alpha-hydroxyprogesterone in patients with gestational trophoblastic neoplasms.

Serum 17alpha-hydroxprogesterone (17-OHP), progesterone (P), and human chorionic gonadotropin (hCG) levels were measured by specific radioimmunoassay in 19 patients undergoing laparoscopy or laparotomy with either unevacuated molar pregnancy or nonmetastatic gestational trophoblastic neoplasms (GTN), in 10 normal pregnant patients at equivalent gestational age (7-21 weeks), and in 4 patients with metastaic GTN following hysterectomy and bilateral salpingo-oophorectomy. All patients with theca lutein cysts had significantly elevated serum 17-OHP levels compared to those in 1) normal pregnancy, 2) patients with GTN and normal-size ovaries, 3) patients with metastatic GTN in the absence of ovaries (P less than 0.02). Levels of serum 17-OHP but not P correlated with the degree of ovarian enlargement (r = 0.87, P less than 0.05). Serum P concentrations in patients with theca lutein cysts, although higher than the levels in cases of GTN with normal-size ovaries, were not significantly different from the levels in normal pregnancy (P greater than 0.05). Serum hCG levels in patients with theca lutein cysts, though higher than the normal pregnancy levels (P less than 0.05), were not significantly different from those in cases of GTN with normal-size ovaries and GTN without ovaries (P greater than 0.05). Under the conditions studied, no correlation was observed between serum hCG and P levels in our cases of GTN. Increased serum 17-OHP level in a patient with GTN suggests the presence of theca lutein cysts.

Endometrial cancer associated with feminizing ovarian tumor and polycystic ovarian disease.

Feminizing ovarian tumors and polycystic ovarian disease may cause endometrial cancer by abnormal, unopposed endogenous estrogenic stimulation. We reviewed the clinical course of 72 endometrial cancer patients with a concomitant feminizing ovarian tumor or polycystic ovarian disease and compared tumor characteristics and treatment results with those exhibited by 523 patients treated for endometrial cancer alone. With functioning ovarian tumor and with polycystic ovaries, the cancer tended to be more often low-grade, low-stage, and superficial than did endometrial cancer alone. The high 5-year and 10-year survival rates observed in our functioning ovarian tumor-polycystic ovary patients support the conclusion that endometrial carcinoma with a coexistent endogenous estrogenic stimulus has a more favorable prognosis (P less than 0.01) than endometrial carcinoma alone.

Gonadotropin receptors in experimentally induced ovarian tumors in mice.

Gonadotropic hormones are required for the induction and maintenance of tumors arising in ovaries that have been transplanted to the spleens of gonadectomized mice. The characteristics of gonadotropin receptors for human chorionic gonadotropin (HCG)-luteinizing hormone on cells from these tumors of varying size, age, and morphology have been determined. The specific binding of 125I-labeled HCG to cells obtained by collagenase digestion, 15 to 65 weeks postimplantation from granulosa cell or luteinized cell, or mixed granulosa-luteal tumors was analyzed by Scatchard plot. Neither the size, weight, duration of implantation, nor histological morphology affected the receptor-binding affinity [equilibrium dissociation constant (Kd), 6 X 10(-10) M], and, presumably, the receptor is qualitatively similar. In contrast, the number of HCG receptors per cell increased 17-fold and was related to the degree of morphological luteinization of the tumor. HCG-sensitive adenyl cyclase was also demonstrated and compared to HCG binding in a highly luteinized tumor.

The Brenner tumor: a clinicopathologic review.

The Brenner tumor of the ovary has been the topic of voluminous clinical and pathologic literature since its original description by Macnaughton-Jones in 1898. One of the major problems confronting most investigators of this uncommon neoplasm has been the question of histogenesis. There is general agreement that the tumor is derived from surface (coelomic) epithelium, as are the serous and mucinous cystadenomas. Most Brenner tumors are asymptomatic except for some which have features suggestive of estrogen production. The major pathologic variants are the proliferating and the malignant Brenner tumors; a poor prognosis is associated with the latter neoplasm. Approximately 30% of all benign Brenner tumors have a second histologic type of tumor in the ipsilateral or contralateral ovary, a serous or mucinous cystadenoma in most cases. Brenner tumors have also been reported in the broad ligament and in the testis on rare occasions.
