Abstract
Knowledge of the evolution of clear cell adenocarcinomas of the vagina and cervix in diethylstilbestrol-exposed progeny has remained elusive despite the known topographical association of these tumors with the tuboendometrial form of vaginal adenosis and cervical ectropion. Twenty radical hysterectomy or radical hysterectomy and vaginectomy specimens of clear cell adenocarcinoma of the vagina or cervix were serially blocked in toto; tuboendometrial epithelium was found in the vagina in 19 (95%) of the cases, usually in greatest concentration at the margin of the tumor, particularly inferiorly. Foci of atypical tuboendometrial epithelium were identified in 16 (80%) of the cases, almost always immediately adjacent to the tumor. Twenty-five of a second group of 47 specimens in which only substantial portions of the vagina or cervix adjacent to a clear cell adenocarcinoma were available for examination also had foci of atypical tuboendometrial epithelium. The frequency with which atypical tuboendometrial glands in the vagina and cervix were associated with the carcinomas and the proximity of the former to the latter provide strong evidence that atypical vaginal adenosis and atypical cervical ectropion of the tuboendometrial type are precursors of clear cell adenocarcinoma.

Abstract
Five thousand seven hundred seventy-eight adenomas or adenomas containing carcinoma from 3215 patients were examined by routine histologic methods for the presence of epithelial metaplasias. Three forms of epithelial metaplasia were encountered: squamous cell metaplasia (0.44%), Paneth cell metaplasia (0.20%), and melanocytic metaplasia (0.017%). In several instances multiple forms of metaplasia were encountered in the same polyp. In those cases in which the paraffin blocks were available, a Grimelius stain was performed. Grimelius-positive cells were present in 63% of the adenomas containing a metaplastic cell type. All cases with Paneth cell differentiation were immunoreactive for lysozyme; all lesions containing areas of squamous differentiation were immunoreactive for keratin except 2. The histopathologic features of these cases are discussed, and it is concluded that rather than representing a true metaplastic process, Paneth cell, squamous cell, and melanocyte differentiation represent the full range of cellular differentiation that endodermally derived tissues can exhibit, particularly when they undergo neoplastic alterations.

Abstract
Among women exposed in utero to diethylstilbestrol (DES) and enrolled in the Diethylstilbestrol Adenosis (DESAD) Project, structural anomalies of the cervix or vagina were found in 25% of the 1,655 subjects identified by review of prenatal records, 43% of the 800 who themselves requested entry into the project, and 49% of the 1,089 referred by physicians but in only 2% of the 963 control subjects. Among the 367 cases found by record review to have complete information on the DES exposure, multivariate analysis indicated close association of the anomalies with the gestational week of first exposure and the total dose. Also, the prevalence rate of the anomalies was lower among subjects who had been pregnant and higher among those with later age at menarche.

Abstract
A study was undertaken to determine whether immunoperoxidase stains for keratin and involucrin, the latter a protein present in cells of stratified squamous epithelium that have differentiated beyond the basal stage, distinguish any differences in squamous cells present in the adenoacanthoma from those in the adenosquamous carcinoma of the uterine corpus. Forty-eight tumors were studied, of which 33 were adenoacanthomas and 15 adenosquamous carcinomas. The patients with adenoacanthomas were slightly younger (mean 61.5 vs. 64.5 years) and had tumors that were generally better differentiated than the adenosquamous carcinomas. The squamous epithelium in every tumor, regardless of histologic type, stained positively for keratin. There were no obvious differences in staining when tumors were stratified for histologic type, grade, or location within the tumor. The glandular portion of both tumor types stained irregularly, but nonetheless positively, for keratin in 71% of the cases. Involucrin was detected in 57% of adenoacanthomas and 87% of adenosquamous carcinomas. The deeper or more central portion of the squamous morules stained only if the more superficial or peripheral areas were positive. The extent of the involucrin staining was less in the adenosquamous carcinomas than in the adenoacanthomas. The glandular component of the tumors did not stain for involucrin. It is concluded that no qualitative differences in the staining reactions with respect to keratin and involucrin distinguish the adenoacanthomas from the adenoaquamous carcinoma. These findings support the argument that the adenoacanthoma and adenosquamous carcinoma represent a spectrum of squamous differentiation in a single tumor type.

Abstract
Forty cases of ovarian lymphoma and two of extramedullary leukemia were examined with emphasis on histologic types correlated with age, modes of presentation, operative findings, including frequency of bilaterality and omental spread, clinical course following therapy, and problems in differential diagnosis. Although most cases were referred with diagnoses other than lymphoma (granulosa cell tumor or dysgerminoma, occasionally anaplastic tumor, Krukenberg tumor, or metastatic breast carcinoma), utilization of sections cut at 4 mu and stained with hematoxylin and eosin, or sections stained by the methyl green pyronine (MGP), naphthol-ASD esterase (NASD) or periodic acid-Schiff (PAS) methods helped bring out the lymphoid or hematopoietic nature of the cells. Sixteen patients were under 20 years of age. They had small noncleaved cell lymphoma (undifferentiated Burkitt's and non-Burkitt's, 10 cases), diffuse immunoblastic large cell lymphoma (4 cases), or acute granulocytic leukemia (2 cases). Twenty-six patients were 29 to 74 years of age and had diffuse large cell lymphoma (10 cases), diffuse immunoblastic large cell lymphoma (9 cases), follicular (nodular) lymphoma (6 cases) or small noncleaved cell lymphoma (1 case). Pain with an abdominal or pelvic mass was the most common presentation. Nine tumors were discovered during investigation of other gynecologic complaints. At laparotomy, the tumors in 55% of cases involved both ovaries, and in 64% also involved extragonadal sites (usually omentum, fallopian tubes, or lymph nodes). Seventeen patients had tumor affecting one ovary, seven of these without any evidence of extragonadal spread. Forty-two percent (15) of 37 patients with follow-up were alive after 2 years. Only nine patients survived more than 5 years; two subsequently died of lymphoma. Favorable prognostic features included: (1) FIGO stage IA; (2) unilateral ovarian involvement; (3) focal involvement of one ovary; and (4) follicular (nodular) lymphoma.

Abstract
Fifty-four cervical condylomatous lesions, with and without nuclear atypia, from 42 women, were studied with the Feulgen microspectrophotometric technique for nuclear DNA quantitation and an immunoperoxidase technique for human papillomavirus (HPV) antigen. All ordinary cervical condylomas (without atypia/dysplasia) had a diploid or polyploid nuclear DNA distribution; 61% had detectable HPV antigen. Among the cervical condylomas with atypia/dysplasia, 55% (17/31) had diploid or polyploid nuclear DNA pattern, and, of these, 59% (10/17) had demonstrable papillomavirus antigen. Fourteen (45%) were aneuploid lesions, 2 of which had a small number of cells with papillomavirus antigen (14%). These findings suggest that the majority of cervical condylomas are related to papillomavirus infection. That lesions with dysplasia, including high degrees of dysplasia, may also exhibit coexistence of papillomavirus infection suggests the possibility of an infectious etiology in the genesis of cervical squamous neoplasia.

Abstract
A total of 452 women with documented exposure in utero to diethylstilbestrol (DES) with epithelial findings present at the time of their initial examination have been evaluated prospectively to determine whether these findings changed over a period of 3 years. The examinations were all performed according to a strict protocol. Findings present at the time of the third annual examination were verified at a fourth examination. A verified decrease in the extent of epithelial findings occurred in 29.2% of these women and a verified increase in 6.6%; 53.1% had no change in the extent of epithelial findings, and 11.1% had a change that could not be verified at the time of the fourth visit. Analysis of many variables failed to identify a strong association between any variable and a decrease in the extent of the findings. It appears that the most important factor in the occurrence of changes in DES-associated findings is the passage of time.

Abstract
A study was performed to determine if ploidy levels of nuclear DNA content could be used as a prognostic index of the biologic behavior of clear cell adenocarcinoma of the vagina and cervix in young females. Forty tumors were examined. Four patterns of nuclear DNA distribution were identified: (1) peridiploid stem cell lines (2N to 3N); (2) peritetraploid stem cell lines (3N to 5N); (3) hypertetraploid stem cell lines (greater than 5N); and (4) highly aneuploid without detectable stem cell lines. Tumors having peridiploid and peritetraploid stem cell lines (low ploidy group) were most often clinical Stage I or II (87%) and were in general associated with a favorable prognosis. Tumors having hypertetraploid stem cell lines and highly aneuploid distribution (high ploidy group) were usually clinical Stage III or IV (65%). Clinically advanced tumors (Stage III or IV) had poor prognosis irrespective of ploidy level. Among the clinical Stage I and II tumors, the low ploidy group had a slightly better prognosis than the high ploidy group. This difference, however, was not statistically significant.

Abstract
Seven cases of ovarian yolk sac tumor (endodermal sinus tumor) with patterns resembling those of hepatocellular carcinoma were encountered in patients 7-43 years of age. Two of the patients had gonadal dysgenesis with a 46XY karyotype. At operation three tumors were confined to the ovary and four were associated with intra-abdominal metastases. Two of the Stage I tumors recurred within one year. The hepatoid pattern was a prominent feature of all the tumors and was exclusive in four of them. In one specimen it merged almost imperceptibly with a polyvesicular vitelline pattern. The hepatoid component of the tumors was characterized by discrete masses, nests and/or broad bands of large polyhedral cells with central nuclei and prominent nucleoli; gland-like spaces, some of which contained mucin, were occasionally evident. Each tumor contained numerous PAS-positive, diastase-resistant intracytoplasmic and extracytoplasmic hyaline bodies. Alpha-fetoprotein and alpha-1-antitrypsin were identified by immunoperoxidase and immunofluorescence techniques in four tumors and albumin in two. Immunoperoxidase stains for chorionic gonadotropin were negative in four cases. Ultrastructural analysis of two specimens disclosed features similar to those of hepatocellular carcinoma.

Abstract
Twenty specimens of uterus and vagina removed because of clear cell adenocarcinoma of the cervix or vagina in women exposed prenatally to diethylstilbestrol were serially blocked and sectioned to study the topographic relation between the carcinoma and the cervical ectropion and vaginal adenosis. Three tumors were cervical; 17 were vaginal. Iodine staining performed on 8 specimens indicated that the carcinoma developed consistently just above the distal limit of the cervical or vaginal surface that failed to stain with iodine, a location that usually corresponds to the distal limit of abnormality visible by colposcopic examination. Microscopic examination disclosed the presence of both cervical ectropion and vaginal adenosis in all the specimens. Mucinous glands were abundant above the tumor. In 18 of the 20 cases, tuboendometrial glands were intimately related to the carcinoma, either surrounding it or abutting its inferior border. These data, in addition to other evidence, suggest that tuboendometrial epithelium, whether in the ectocervix or vagina, provides the bed from which clear cell adenocarcinoma develops.

Abstract
Autoradiographic analysis of [3H]-estrogen nuclear binding sites was performed on developing genital tracts (uterus, cervix and vagina) of mice 1 to 90 days postpartum. During days 1 to 15 postpartum, nuclear estrogen binding sites were observed exclusively within mesenchymal cells; epithelial cells did not exhibit nuclear labelling. At 18 days postpartum vaginal and cervical epithelial cells exhibited nuclear estrogen binding sites for the first time, whereas the initial appearance of estrogen receptor activity in the epithelium of the uterus was detected at 20 days postpartum. Thereafter, nuclear estrogen binding sites were maintained in both epithelial and stromal cells into adulthood. The acquisition of nuclear binding sites within epithelium of female genital organs at 18 days is discussed in terms of epithelial-mesenchymal interactions and the acquisition of growth responsiveness.

Abstract
The clinical and pathologic aspects of 21 cases of mixed gonadal dysgenesis (MGD) were studied. The gonads in 15 patients consisted of a macroscopic testis and a streak gonad; six patients had variants, including two with bilateral testes and four with bilateral streak gonads or tumors. Functionally, the gonads were incompetent. Testes 1) failed to completely inhibit müllerian development, 2) failed to support full differentiation of mesonephric duct structures, 3) failed to adequately masculinize development of the external genitalia, or 4) often failed to mediate their own descent, resulting in asymmetry of the internal and external genitalia. None of the streak gonads mediated normal female adolescent development or fertility. Microscopic examination revealed that every gonad, regardless of its gross appearance, was morphologically abnormal. Although gonads with seminiferous tubules usually developed to a moderately advanced state, macroscopically resembling testes, the hilar zone remained architecturally disorganized; the cortex invariably lacked more than a rudimentary tunica albuginea or exhibited partial ovarian differentiation, sometimes even with a rare primordial follicle. Over time, the seminiferous tubules atrophied and hyalinized. Gonads that grossly resembled streak gonads were observed microscopically to be composed of a stroma resembling that of normal ovarian cortex. In patients more than several years of age, the entire complement of germ cells in streak gonads disappeared. It is suggested that patients with MGD be raised as females. Early removal of gonads will prevent the development of gonadoblastoma and dysgerminoma. If the uterus is retained and the patient is subsequently given exogenous estrogen, care should be taken to detect early any signs of the development of endometrial carcinoma or its precursor, to which these patients may be prone.

Abstract
An in vivo model is described for the study of human uterovaginal development in the presence and absence of the teratogenic drug diethylstilbestrol (DES). Intact reproductive tracts from fragments of 29 human embryos and fetuses 5.0 to 17.7 weeks of age obtained after dilatation and curettage were grown for four weeks in vivo in athymic (nude) mice that were either untreated (control) or implanted subcutaneously with a DES pellet. Control specimens grown in vivo continued their anticipated morphogenesis for equivalent in-utero ages; the normal processes observed included fusion of the paired embryonic müllerian ducts into a single uterovaginal canal, stratification of endometrial and tubal mesenchyma into inner (presumptive endometrial stroma) and outer (presumptive myometrium) layers; plication of tubal and endometrial mucosa; uterine gland formation; and stratification (transformation) of the simple columnar epithelium of the vagina and cervix into a stratified squamous plate. Specimens exposed in vivo to DES exhibited anomalies, many of which mimicked those observed clinically in young women exposed prenatally to DES. Glandular epithelium (adenosis) was found in the vagina. The upper genital tract was malformed; its growth was stunted, and the inner and outer stromal layers of the uterine corpus and fallopian tubes failed to segregate. The authors conclude that the in vivo model that they describe, with its built-in controls, provides a valid approach for examining the dynamics of morphogenesis and cytodifferentiation in developing human genital tracts under experimentally regulated conditions.

Abstract
Eighty-one primary ovarian carcinoids and intraovarian metastases from six mid-gut carcinoids were examined for the presence of tumor cells immunoreactive with antisera raised against various neurohormonal peptides, mostly of gastroenteropancreatic (GEP) origin. Twenty of the primary and two of the metastatic carcinoids contained such tumor cells. The incidence of tumors with any kind of neurohormonal peptide immunoreactive tumor cells was 53% in the trabecular carcinoids, and 42% in the strumal carcinoids, whereas the incidence was much lower (7%) in the insular type. Immunoreactive pancreatic polypeptide (PP), glucagon, enkephalin, and somatostatin were those neurohormonal peptides most commonly observed in the tumor cells of the primary carcinoids. Those less commonly found were substance P, calcitonin, VIP, neurotensin, beta-endorphin, and ACTH. Four metastatic carcinoids were nonreactive with all the antisera used. Cells storing immunoreactive insulin, glucagon, PP, VIP, gastrin, substance P, or enkephalin were found in one of the two remaining metastatic carcinoids; in the other only gastrin-immunoreactive tumor cells were observed. The occurrence and distribution of tumor cells storing the neurohormonal peptides in ovarian carcinoids are discussed in relation to their possible origin in the ovary and to carcinoids in the gut.

Abstract
The slides of 233 patients included in a case-control study of estrogens and endometrial cancer were reviewed to determine how often endometrial cancer was misdiagnosed and whether patients with uterine cancer had other coexistent endometrial diseases. Reasonably close agreements were found among the original diagnoses and those of three additional reviewers (the total range of disagreements among all pathologists was from 2% to 16%). Proliferative and hyperplastic endometrium coexisted in many specimens from patients with endometrial cancer, and especially in those who had used estrogen replacement therapy. In contrast, estrogen therapy had seldom been used by patients whose cancers were not accompanied by these proliferative and hyperplastic lesions. In addition, these changes were found significantly more often in women with grade 1 cancers than grade 2 or 3 cancers. We conclude from these data that diagnostic misclassification is uncommon and that coexistent proliferative and hyperplastic lesions occur frequently, especially among women with grade 1 cancers. The data also suggest that the frequent finding of grade 1 cancer in estrogen users is due to bleeding that results from the stimulated coexistent benign proliferating endometrium.

Abstract
Metastases which present as palpable masses in the pelvis occasionally masquerade as primary neoplasms of the ovary. Although most such cancers originate in the stomach and large intestine, the histories of two patients are presented in whom the ovarian tumors were discovered prior to the detection of the breast primary. Three similar cases were found in the literature and are reviewed.

Abstract
This report presents the cytologic findings and the rates of dysplasia for 4,589 young women enrolled in the National Cooperative Diethylstilbestrol-Adenosis (DESAD) Project. Mucinous columnar cells and/or metaplastic squamous cells with or without mucinous droplets were encountered in 22% of vaginal scrape smears from all diethylstilbestrol (DES)-exposed participants identified by review of prenatal records and in 43% of women in whom vaginal epithelial changes (VEC) were observed by colposcopy or by iodine staining. The frequency of cellular findings in the vaginal scrape smears was closely related to the timing of the administration of the DES to the mother. With increasing age of the daughters, the overall frequencies of both the mucinous and metaplastic cells decreased; relative to each other, an increasing proportion was metaplastic squamous cells. These data suggest that, as the women grow older, vaginal adenosis regresses by the process of squamous metaplasia. Endometrial type cells were found in 2% of vaginal scrape smears. Their cyclical occurrence during the menstrual cycle and lack of correlation with the presence of VEC indicated an origin from the uterine corpus rather than the tuboendometrial type of adenosis. Squamous cell dysplasia of the vagina and cervix was detected by biopsy or scrape smear specimens in 1.8% of DES-exposed women in the record review group. The rate of unexposed women was twice as high. In general, the rates of dysplasia were higher in the cervix than vagina, and the more severe degrees of dysplasia were encountered only in those women who were referred to the DESAD Project or who themselves requested entry. Four patients who were referred or who themselves requested entry were found to have clear cell adenocarcinoma of the vagina. The vaginal smear provided the first clue to the presence of an abnormality in three of them.
