[Ovarian carcinoid tumors: immunohistochemical and ultrastructural study of 8 cases].

Eight ovarian carcinoids, 4 trabecular and 4 strumal have been studied immunohistochemically for polypeptide hormones; three of them were also examined with the electron microscope. Seven of eight cases were positive for at least one polypeptide hormone. The trabecular parts of the 4 cases of strumal carcinoid were positive for pancreatic polypeptide. As the vesicular regions of these 4 cases were positive for thyroglobulin and for pancreatic polypeptide, we suspect the existence of "hybrid" thyroid and neuroendocrine cells. The electron microscopic examination revealed: the cell in the insular carcinoid had no distinct polarization and contained electron-dense granules of varying shape; in the trabecular part of the strumal carcinoid the cells were polarized and contained round electron-dense granules.

Epidemiologic pathology of ovarian cancer from the Vaud Cancer Registry, Switzerland.

OBJECTIVE: To provide further information on the descriptive epidemiology and survival of ovarian cancer patients by specific histologic types. STUDY DESIGN: Descriptive epidemiological study. Cases of ovarian cancer registered between 1974 and 1988 in the Vaud Cancer Registry, Switzerland (based on a population of approximately 530,000 inhabitants), were analysed. RESULTS: A total of 649 cases were registered, corresponding to an overall age-standardized (world population) incidence of 9.6/100,000. The most common histotype was serous carcinoma (41%, incidence rate 4.0/100,000), followed by endometrioid (13%), mucinous (12%), clear cell (5%), and undifferentiated carcinomas (3%); 20% of the cases were classified as 'epithelial, unspecified', and 6% were non-epithelial cancers. There was a tendency for the incidence of all epithelial types to rise up to the seventh decade of age, and to level off thereafter. The increases between the ages of 45 and 65 were, however, mostly in serous carcinomas whose proportion of total ovarian epithelial cancer peaked in middle age. Overall, 5-year relative survival was 32%. Survival rate was 32% for serous carcinomas, but was significantly higher for endometrioid (51%) and, among nonepithelial neoplasms, for germ-cell cancers (68%). Survival rates were poor for undifferentiated and 'epithelial, unspecified' carcinomas (16%). Relative survival was systematically higher below age 60 than at age 60 or over. In the two subsequent calendar periods examined (divided according to the approximate time when the use of platinum-based chemotherapy began to spread, i.e., 1982), 5-year relative survival rates were 28% and 36%, respectively (chi 1(2) = 6.1, p = 0.02). CONCLUSION: The present report is a population-based description of the epidemiologic pathology and prognosis of ovarian cancer, and provides evidence of a significant improvement of survival over the past decade. This may be due to changed diagnostic methods (e.g., ultrasonography), improved surgical approach, (platinum-based) chemotherapy, or a combination of all these factors.

[Malacoplakia of the vagina. Cytological, histological and ultrastructural study of a case].

A case of vaginal malakoplakia is reported in a 65 year old patient receiving prednisone for fifteen months for the treatment of collagen colitis. The macroscopic and microscopic appearance, cytological examination of the vaginal smear and ultrastructural examination were typical of malakoplakia. To our knowledge, this is the seventh detailed case of vaginal malakoplakia and the twenty-sixth case of malakoplakia of the female genital tract.

[Necrotic oophoritis due to cytomegalovirus].

In a 54-year-old woman with malignant lymphoma, cytomegalovirus oophoritis was disclosed at autopsy. The virus, which is recognized by its typical nuclear inclusions, reaches the cortical stroma of the ovaries and causes zones of necrosis there. Its presence is confirmed by ultrastructural and immunohistochemical examination. The real frequency of ovarian involvement is difficult to evaluate since histological examination of ovaries is not routinely performed at autopsy. As far as we know the present case is the seventh detailed observation of cytomegalovirus oophoritis published in the literature.

Cervical intraepithelial glandular neoplasia (adenocarcinoma in situ and glandular dysplasia). A correlative study of 23 cases with histologic grading, histochemical analysis of mucins, and immunohistochemical determination of the affinity for four lectins.

Twenty-three cases of cervical intraepithelial glandular neoplasia (CIGN)--a term encompassing adenocarcinoma in situ and glandular dysplasia of the uterine cervix--were studied histologically, histochemically for mucins (neutral mucins, sialomucins and sulfomucins), and immunohistochemically for the affinity of four lectins (WGA, PNA, RCA, UEA). For comparison, six cases of cervical invasive adenocarcinoma and ten cases of cervices without tumor were similarly studied. Criteria for histologic grading of CIGN into three degrees were proposed according to the hyperchromasia and the stratification of nuclei, number of mitoses, and amount of intracellular mucin. Two different types of CIGN were distinguished according to their histological aspect and their mucin pattern: CIGN type A, where the mucin pattern was qualitatively similar to that of normal endocervical mucosa, i.e., neutral mucins, sulfomucins and sialomucins; and CIGN type B, where the glandular cells resembled small intestinal goblet cells and the mucins consisted of neutral mucins and sialomucins with the absence of sulfomucins. Nine cases of CIGN were of type A, 2 of type B, and 12 of both type A and B. Differences in lectin binding existed between normal columnar cells, CIGN, and invasive adenocarcinomas, as well as between CIGN of type A and B. The intensity of the positive immunochemical reaction varied, as well as the type of binded lectin and its localization in the cell. There was a great heterogeneity in the same histologic group from one case to another, and even in the same case from one cell to another.

[Detectability of glaucomatous visual field defects with the Octopus automatic perimeter. A comparison between program G-1 and programs 31 and 32 and their combinations].

Twenty-three patients between 31 and 76 years of age suffering from either hypertension or glaucoma underwent automatic perimetry with Octopus programs 31 or 32, followed by program G-1. This was done to compare the information content of the latter, new program with that of the former two, long-used in different combinations. Only one eye of any one patient was considered in this study. Using an evaluation program, the G-1 program calculates the so-called "field indices" which help to interpret the results. These field indices are the mean differential light sensitivity threshold (mDLS), the mean defect (MD), the loss variance (LV), and the corrected loss variance (corrected for short-term fluctuations (CLV)). In order to compare programs 31, 32, and their combination 31 + 32, with the field indices of program G-1, the mean DLS was taken from the Delta evaluation program, while the mean defect, the loss variance, and the corrected loss variance were calculated on the basis of programs 31, 32, and the combination of them. The mDLS and mean defect determined with program G-1 were significantly different from those found with programs 31, 32, and the combination of them. On the one hand, this was due to the difference in test patterns, that of G-1 being more centrally weighted; on the other hand, this is indicative of the precision and discrimination capability of Octopus measurements. Calculation of loss variance and corrected loss variance reveals no significant difference between the examination methods as regards these field indices, that is, between G-1 and 31, 32, or 31 + 32.(ABSTRACT TRUNCATED AT 250 WORDS)

[Early diagnosis of premalignant and malignant lesions of the endometrium. Evaluation of a device for collecting intrauterine samples (the Inocurette) compared with exploratory curettage].

Screening methods for detecting more accurately carcinoma of the endometrium is becoming increasingly important because of the rising incidence of the condition. Inocurette has recently been invented to combine a scraping action with suction. This study investigates 385 patients who were admitted for diagnostic curettage or hysterectomy to which were added a series of 120 patients who were examined as out patients. Inocurette has a sensitivity of 86% and a specificity of 99%. It therefore can be considered as a reliable method of screening for the limits within which fractional diagnostic curettage should be used. Marked pain and great difficulty in introducing the apparatus made its use limited in respectively 15% and 14.5% of cases. So, the method is acceptable and useful within these limits. The results could be improved if on the one hand a thinner apparatus could be designed and on the other hand a substance could be found to soften the cervix so that it became easier to introduce the apparatus.

[Prevalence of infectious diseases at the Vaud University Hospital Center].

The prevalence of infectious diseases at our hospital (Centre hospitalier universitaire vaudois, Lausanne [CHUV], 900 beds) was studied retrospectively over a two years period (1980-1981). The medical diagnosis of 30203 patients recorded in the computerized medical archives, representing 93% of the patients admitted during the period of observation, was reviewed. To assess the reliability of the computerized data, quality control was carried out through detailed analysis of all the histologically proven appendicitis recorded during 1981. 88% of the histologically proven appendicitis were registered in the computer and the diagnosis was specific in 87% of cases. An infectious disease was the primary reason for admission in 12.8% of the patients (3873) during the study period. Altogether, 20.2% of patients presented with an infection during their hospital stay. Because of the retrospective nature of the study it was not possible to determine whether these additional infections were nosocomially acquired. The organ systems most frequently infected were the respiratory tract (28.5% of all infections), the digestive tract (20.5%), the skin and osteoarticular system (16%) and the urogenital tract (11.6%). An infection was the primary reason for admission of 40.2% of the patients hospitalized in the dermatology service, of 19.7% of patients admitted in internal medicine, of 15-17% of the patients admitted in pediatrics, ENT and general surgery, and of 1-2% of the patients admitted in neurosurgery and radiotherapy. These observations highlight the continuing importance of infectious diseases in a modern hospital, in spite of high socio-economic levels, stringent hygiene and epidemiologic measures, and modern antibiotic availability.

Adenocarcinoma in situ and invasive adenocarcinoma of the uterine cervix. An immunohistologic study with antibodies specific for several epithelial markers.

The distribution of carcinoembryonic antigen (CEA), secretory component (SC), fat globule membrane antigens ( FGMA ), and keratin was determined immunohistochemically in 22 invasive adenocarcinomas of various types and in 9 adenocarcinomas in situ of the uterine cervix. In the invasive adenocarcinomas 77% were positive for CEA, 47% for SC, 89% for keratin, and 77% for FGMA . In adenocarcinomas in situ 67% were positive for CEA, 11% for SC, and 44% for keratin. The location of the markers was variable in the cells, and the cells in a tumor were irregularly positive. For a given histologic type there were several phenotypes. No correlation was found between histologic types of invasive adenocarcinomas and the various phenotypes. It remains to be shown whether a particular phenotype has a particular biological behavior. The detection in the serum of the markers shown in histologic preparations could be useful in the postsurgical monitoring.

Autoimmune oophoritis.

A 43-year-old para 3 woman presented with a six-year history of progressive oligomenorrhea and hypomenorrhea. A total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed for the suspicion of ovarian cysts. On histologic examination, the ovaries contained lymphocytic and plasma cell infiltrates in relation to the theca interna of growing follicles, to the corpora lutea and to the endocrine hilar cells. The infiltrates increased in density with the follicular maturation and culminated against the corpora lutea. The plasma cell population was polyclonal. No antibodies to ovarian tissue components could be demonstrated in the patient's serum by means of immunohistochemistry; but antibodies to the zona glomerulosa of adrenal cortex were detected by serologic means. Although a rare disease, autoimmune oophoritis must be recognized histologically because it is a cause of ovarian failure and because it indicates that the patient is at risk of developing associated Addison's disease.

Placental site trophoblastic tumor (trophoblastic pseudotumor) of the uterus with metastases and fatal outcome. Clinical and autopsy observations of a case.

A 41-year-old woman who 5 years earlier had a hysterectomy for a placental site trophoblastic tumor (formerly called trophoblastic pseudotumor) was readmitted to the hospital with pelvic recurrence and multiple lung metastases. Despite an initial decrease in the size of the lung metastases and concomitant lowering of the serum values of human chorionic gonadotropin (beta-HCG) from 2,200 to 40 ng/ml, combined chemotherapy became ineffective. The patient died 4 months later with widespread metastases. The clinical course and the autopsy findings of this case are reported and compared with the two similar cases reported in the literature.

Endolymphatic stromal myosis. Surgical and hormonal treatment of extensive abdominal recurrence 20 years after hysterectomy.

This report describes the clinicopathologic features of a 49-year-old woman who was reoperated on for bulky abdominal metastases 20 years after hysterectomy for endometrial stromal myosis (ESM). The levels of estrogen (ER) and progesterone (PR) receptors measured in the resected tumorous tissue amounted to 48.3 and 71.4 femtomoles (fmol)/mg cytosol protein, respectively. After medroxyprogesterone acetate (Depo-Provera; Upjohn) treatment of 16 months duration, the unresected pelvic tumor mass compressing the bladder and the left ureter had decreased in volume and hydroureteronephrosis had regressed. The efficacy of the therapy was monitored by computed tomography. Two years and nine months after surgery, the evolution of the tumor seems well-controlled by continuous progestin therapy and the patient is living without symptoms.

Morphology of adenocarcinoma in situ of the uterine cervix: a study of 14 cases.

Fourteen cases of adenocarcinoma in situ (ACIS) of the cervix in patients 30 to 52 years old were studied. In its pure form (four cases, ACIS was discovered cytologically, but when associated with a squamous abnormality (ten cases), it was found histologically. Two different types of ACIS were distinguished both histologically and cytologically. The first type, which was similar to the common form reported in the medical literature, predominated in 12 cases, and consisted of cells with hyperchromatic and pseudo-stratified nuclei. The second type, which predominated in two cases, displayed a conspicuous structural disorder with unequal, larger, and often clear nuclei containing enlarged nucleoli.

Ovarian hypoplasia with follicular calcifications.

The clinical features and the ovary biopsy findings of two cases of ovarian hypoplasia are presented. Both patients, 20 and 34 years of age, complained of primary amenorrhea. One patient presented growth retardation with genital and breast infantilism. The other patient, who received substitutive estrogen therapy, displayed normal adult secondary sexual characteristics. The chromosomal karyotype was 46,XX in both patients. The internal genital organs were hypoplastic. In the ovaries, the follicular maturation did not go beyond the secondary follicles which underwent atresia with a strange process of calcification beginning in the ova. The etiologic factors of this phenomenon are unknown. The authors found only one analogous case in the literature.

[Giant cell arteritis affecting the female genital tract. 2 case reports].

Localisation of giant cell arteritis in the female genital organs is very rarely found in sections removed at operation, although this kind of arteritis is a systemic condition. This article reports two new cases to add to the seven cases that have already been reported in the literature. The first case was that of a woman of 78 year of age who was investigated because she had fever, dyspnoea, pains in her chest, pronounced debility and loss of weight. A salpingo-oophorectomy was carried out because she had a parovarian cyst which proved to be benign. Unexpectedly however histological examination revealed that she had giant cell arteritis in the ovary and in the tube, and this diagnosis explained the clinical picture. The second case was that of a 75 years old woman treated intermittently over two years with Prednisone for vague arthralgia. When she had had a sub-total hysterectomy with bilateral salpingo-oophorectomy because of fibroids the organs were removed in order to improve her urinary incontinence and the giant cell arteritis was discovered histologically in the uterus, the ovaries and the tubes. In this second case the unexpected diagnosis clarified the clinical picture.

Trophoblastic pseudotumor of the uterus: clinicopathologic report with immunohistochemical and ultrastructural studies.

The clinicopathologic feature of two cases of trophoblastic pseudotumor of the uterus are presented and compared with previously reported cases. In both cases, cancer was erroneously diagnosed. One patient, 27 years of age when first examined, presented metrorrhagia 10 months after a full-term delivery. The lesion was entirely removed by curettage and was no longer found in the hysterectomy specimen. The patient is alive and well more than 17 years after therapy. The other patient, 36 years of age at the initial examination, presented with metrorrhagia 23 months after a therapeutic abortion. The pseudotumor infiltrated the full thickness of the uterine wall. The patient is alive and well 3 years and 7 months after hysterectomy and radiation therapy. Histologically, the tumor consisted of large cells invading the myometrium in small clusters either as cords or as single cells. There were 2 mitoses/10 HPF of which some were atypical. Tumor cells containing chorionic gonadotropin (hCG) and a pregnancy-specific protein (SP1) were demonstrated immunohistochemically (alpha 2-PAG) and placental lactogen (hPL) in one case. Ultrastructurally, trophoblastic pseudotumor closely resembled cytotrophoblastic cells of the basal plate of the placenta.
