Abstract
Serous cystadenoma, often known as ovarian serous cystadenoma, is one of the common benign ovarian neoplasms. On the other hand, primary retroperitoneal serous cystadenoma is an extremely rare benign entity whose pathogenesis has not been well understood. Clinical presentation and symptomatology vary greatly and are highly dependent on the size and location of the lesion. Primary retroperitoneal serous cystadenomas are homogeneous, unilocular, thin-walled cystic masses. If they grow large enough, they tend to compress and deform adjacent organs, giving clinicians a misimpression of malignant pattern of behavior. Therefore, it is crucial to differentiate benign primary retroperitoneal serous cystadenomas from other epithelial and nonepithelial cystic lesions or masses involving retroperitoneal regions. Management-wise, complete cyst excision without rupture or spillage of the cyst contents is the recommended therapeutic method for primary retroperitoneal serous cystadenomas. This review will highlight the current knowledge on its pathogenesis and discuss its histopathologic features and differential diagnoses from the pathologist's point of view.

Abstract
Primary retroperitoneal serous cystadenomas (PRSCs) are rare cystic lesions whose pathogenesis is currently not well understood. Although the vast majority of tumors are benign, early recognition and resection is necessary to avoid malignant transformation, rupture, and secondary infection. Here we present the case of a 79-year-old woman who presented with confusion, visual hallucinations, and a history of fall. As part of the work-up for abdominal distension, computed tomography scan of the abdomen and pelvis was performed, which revealed a right-sided retroperitoneal cystic lesion measuring 26.6 × 16.7 cm in size. The lesion was resected laparoscopically, and the surgical specimen measured 28 × 17 cm. Histology revealed a serous cystadenoma. The postsurgical course was uneventful, and no radiological recurrence was noted on 3 months follow-up. Very few primary retroperitoneal cystic lesions have been reported in the literature. Most lesions are benign and predominantly occur in females. They may remain asymptomatic for long periods of time and are usually discovered when they reach very large in size. In rare cases, these lesions may have malignant potential. Diagnosis of PRSC should be considered in the differential diagnosis of all retroperitoneal cysts.

Abstract
This study correlated the histologic and immunohistochemical features of cervical and endometrial glandular carcinomas (adenosquamous carcinoma [ADENSQ] and ade nocarcinoma [AC] ) with clinical outcome. A series of 87 uterine glandular carcinomas (53 cervical, 33 endometrial, and 1 arising in both cervix and endometrium) were histologically classified into mullerian subtypes: 28 ADENSQ, 19 serous AC, 19 mu cinous AC, 15 endometrioid AC, and 6 clear cell AC. Utilizing both nuclear and archi tectural features, 66 glandular carcinomas were high histologic grade (3) and 21 were low histologic grade (1 or 2). Immunohistochemical studies performed on 83 of the cases showed: 33 + for monoclonal carcinoembryonic antigen (CEA-M); 38 + for polyclonal CEA (CEA-P); 26 + for placental alkaline phosphatase; 18 + for CA 125; 29 + for CA 19-9; 24 + for vimentin; 60 + for cytokeratin CAM 5.2; and 81 + for cytokeratin AE 1 : 3. The following significant correlations were identified. ADENSQ histology was associated with CEA-M staining (P < .025), and mucinous histology was associated with CA 19-9 staining (P < .025). Cervical primary site was associated with ADENSQ histology (P < .001) and staining with CEA-M (P < .025) and CEA-P (P < .05). Endometrial primary site was associated with endometrioid histology (P < .001). Forty-five patients had recurrent disease, 30 patients were disease-free for more than 1 year, and 12 patients had insufficient follow-up evaluation. Recurrent disease was associated with stage III or IV tumors (P < .001), grade 3 histology (P < .001), serous differentiation (P < .001), invasion to at least the middle third of the myometrium (P < .001) and large size of residual tumor at hysterectomy (mean 3.9 cm versus 1.3 cm, P < .005). Disease-free survival was associated with endometrioid differentiation (P < .05), strong CEA-M staining (P < .001), CEA-P staining (P < .025), and CA 19-9 staining (P < .05). Considering only stage 1 and 2 patients, grade 3 histology ( P < .025), deep myometrial invasion (P < .01), and size (P < .05) were still associated with recurrence and strong CEA-M staining (P < .025) was still associ ated with disease-free survival. However, strong CEA-M staining, deep myometrial invasion, and size of tumor after hysterectomy were all associated with histologic grade. Considering just histologic grade 3 carcinomas in stage 1 and 2 patients, absence of strong CEA-M staining, deep myometrial invasion, and size of tumor was no longer associated with recurrent disease. Histologic grade was the only independent predictor of prognosis in stage I and II patients. Int J Surg Pathol 1 (1): 13-24, 1993

Abstract
A series of 53 carcinomas of the uterine cervix with a component of glandular differen tiation were identified and included 29 pure adenocarcinomas and 24 adenosquamous carcinomas. Cervical adenosquamous carcinomas were defined as glandular carcino mas mixed with a squamous carcinoma component. Cervical pure adenocarcinomas were classified into various Mullerian subtypes analogous to other portions of the female genital tract yielding 14 mucinous/endocervical, 11 serous, 2 clear cell, and 2 endometrioid adenocarcinomas. A panel of immunostains including monoclonal carcinoembryonic antigen (CEA-M), polyclonal carcinoembryonic antigen (CEA-P), CA 125, CA 19-9, placental alkaline phosphatase, and vimentin showed no association with histologic differentiation except for mucinous/endocervical subtype (7 of 11 CEA- M or CEA-P positive and 7 of 11 CA 19-9 positive). Recurrent disease in adenocarci noma and adenosquamous carcinoma was associated with stage III or IV disease at presentation (P < .001), serous histology (P < .05), absence of strong CEA-M staining (P < .025), absence of strong CEA-P staining (P < 05), and presence of vimentin staining (P < .05). No association was found between survival and other histologic subtypes of adenocarcinoma (mucinous/endocervical, endometrioid, or clear cell), ad enosquamous carcinoma, histologic grade, lymphatic invasion, age, or immunohisto chemical staining for CA 125, CA 19-9, or placental alkaline phosphatase. When only stage I and II disease was considered, there was no correlation between histology or immunohistochemistry and outcome. Int J Surg Pathol 1(3):181-190, 1994

Abstract
MN protein is the product of the newly described endogenous MN gene that is expressed in the tumorigenic phenotype of HeLa X fibroblast somatic cell hybrids. MN protein has carbonic anhydrase and putative DNA binding activity. With the exception of gastric mucosa, MN protein is expressed in neoplasia, particularly uterine cervix carcinoma, but not in benign tissue. This investigation examined the pathogenetic and prognostic significance of MN-protein immunoreactivity in uterine cervix carcinoma with glandular differentiation. Paraffin sections from 77 cervix carcinomas with glandular differentiations including 36 pure adenocarcinomas and 41 adenosquamous carcinomas were immunostained with anti-MN-protein (M-75 monoclonal proprietary; Ciba Corning Diagnostics, Alameda, CA). A total of 64.9% of cervix carcinomas with glandular differentiation exhibit MN-protein immunoreactivity localized to plasma membranes, cytoplasm, and some nuclei of neoplastic cells only, but not in adjacent benign tissue. The MN-protein staining intensity and distribution was as follows: 37.7% strong diffuse (≥ 50% cells positive), 19.5% strong focal (< 50% cells positive), and weak (7.8%). Immunoreactivity occurred in both squamous and glandular areas of adenosquamous carcinomas and was unrelated to histopathologic features. Follow-up information was available on 67 patients: 31 exhibited recurrent disease (7 pelvic, 14 distant, and 10 both) at 1–144 months (mean 37, median 14), and 36 were disease-free at 12–216 months (mean 67, median 44.5). MN-protein immunoreactivity (all positives, both standard diffuse and strong focal, or standard diffuse only) exhibited no association with clinical outcome. Recurrent disease was associated with nuclear grade ( P < .001), lymphatic invasion ( P < .005), size on clinical examination or pathologic evaluation ( P < .005), pelvic lymph node involvement ( P < .05), and clinical stage ( P < .05). MN-protein immunoreactivity did not correlate with these features and did not help predict which patients would develop recurrence in the good prognosis groups. Our data show that expression of MN-protein is associated with cervix carcinoma with glandular differentiation carcinogenesis. MN-protein immunolocalization may have a diagnostic role in confirming cervix carcinoma with glandular differentiation in histologically challenging cases.

Abstract
Ovarian tumors comprise a heterogeneous group of lesions, displaying distinct tumor pathology and oncogenic potentiel. These tumors are subdivided into three main categories: epithelial, germ cell, and sex-cord stromal tumors. We report herein the newly described molecular abnormalities in epithelial ovarian cancers (carcinomas). Immunohistochemistry and molecular testing help pathologists to decipher the significant heterogeneity of this disease. Our better understanding of the molecular basis of ovarian carcinomas represents the first step in the development of targeted therapies in the near future.

Abstract
INTRODUCTION Retroperitoneal mucinous cystic neoplasms are uncommon, and little is known about the etiology of the disease. Malignant forms of these are extremely rare. Here, we report a case of primary retroperitoneal mucinous cystadenocarcinoma (PRMC), which demonstrated unexpectedly aggressive progression despite finding only a limited area of adenocarcinoma. PRESENTATION OF CASE A 62-year-old woman with a complaint of abdominal discomfort was admitted to the hospital. Abdominal CT and MRI showed multiple large retroperitoneal cysts dislocating the right kidney nearly to the center of the abdomen. Transabdominal resection of the cysts was performed. Those cysts contained 1100ml of mucinous fluids in total. Cytological examination of those fluids revealed no malignant cells. The cyst wall was lined with mucinous epithelial cells, and contained some ovarian-type stroma. Also, there was a focal area of adenocarcinoma in the cyst wall, and the lesion was diagnosed as primary retroperitoneal mucinous cystadenocarcinoma. Eight months later, the patient developed lumbar bone metastasis. Chemotherapy with S-1, an oral fluoropyrimidine, and docetaxel had been begun immediately; however, the disease had rapidly spread in the retroperitoneum. Eventually, the patient died of the disease 15 months after surgery. DISCUSSION Retroperitoneal mucinous cystic neoplasms are considered to be metaplasia of embryonal coelomic epithelium. Complete excision without rupture is essential. However, variance of biological aggressiveness might exist in PRMCs. CONCLUSION Retroperitoneal mucinous cystadenocarcinoma is a rare tumor, and it is urgently necessary to elucidate the etiology of an effective therapy for the disease.

Abstract
Primary retroperitoneal mucinous cystadenocarcinomas are rare tumors with a controversial pathogenesis. Present report describes a 74-year-old woman with a retroperitoneal cystic pelvic mass. Her past medical history included appendectomy, bilateral salpingo-oophorectomy, and a hysterectomy. An explorative laparotomy was performed and the mass was completely excised. Definitive pathology revealed a primary retroperitoneal mucinous cystadenocarcinoma of the ovarian type. Further management consisted of four cycles carboplatin. She had a recurrence after 8 months and died 31 months after the initial diagnosis. Primary retroperitoneal mucinous cystadenocarcinomas are distinct entity, with the same poor prognosis as their ovarian counterpart.

Abstract
Primary adenocarcinoma of the vagina is rare, and mucinous-enteric differentiation is exceptional. A few sporadic cases of primary vaginal adenocarcinoma with mucinous-enteric differentiation have been reported. Reports of the clinical histories, pathologic findings, and immunohistochemical studies of two cases of primary vaginal adenocarcinomas in a 67-year-old and in a 45-year-old woman are presented. Knowledge of the differentiation of Mullerian epithelium and immunohistochemistry studies are helpful to better characterize these tumors.

Abstract
OBJECTIVE Serous ovarian, Fallopian tube, and peritoneal adenocarcinomas are remarkably similar, both in their morphology, as well as in their clinical behavior. Despite extensive clinical and fundamental research, controversy still exists on the origin of serous female adnexal tumors. Difficulties in identification of site of origin at late stage the of disease at detection, when ovary, Fallopian tube, and the abdominal cavity are usually all involved, in addition to their macroscopic and microscopic resemblance, are major causes of this debate. In 3 hypotheses, 3 possible tissues of origin are proposed: the ovarian surface epithelium, the Fallopian tube epithelium, and the secondary Mullerian system. STUDY DESIGN We searched for all peer-reviewed articles and reviews that examined "serous ovarian carcinoma," "Fallopian tube carcinoma," "Mullerian system," "ovarian surface epithelium," "tubal epithelium," and "peritoneal." We included only articles that could give information on the origin of serous carcinomas. Additional articles were added by examining references of overview articles in relevant fields. RESULTS Discussed are the experimental data underlying these hypotheses. CONCLUSION An attempt is made to integrate the 3 hypotheses into a comprehensive model of serous intraperitoneal adenocarcinogenesis. It can be concluded that the Fallopian tubes play a major role in the development of female serous cancer.

Abstract
Primary retroperitoneal cystic tumor is extremely rare, and its histogenesis and biological behavior remain speculative. Two surgical cases of retroperitoneal mucinous cystadenoma (Case 1, an 18-year-old woman; and Case 2, an 85-year-old woman) are reported. The cystadenomas in these cases were mainly lined by a monolayer of columnar or thin flat cells. Case 1 was positive for mucin and epithelial membrane antigen, whereas Case 2 was positive for a mesothelial marker (calretinin). Ciliated epithelium was also interspersed in Case 2. Some parts showed papillary projections, resembling well-differentiated papillary mesothelioma. Within the cyst walls of both cases, ovarian-like stroma that was positive for both estrogen and progesterone receptors was found. Interestingly, focal nodular hyperplasia of the liver was also detected in Case 1. We believe the retroperitoneal mucinous cystadenoma might have arisen from the peritoneum via mucinous epithelial metaplasia with a phenotype of extragenital Mullerian system.

Abstract
OBJECTIVE We present a case of primary retroperitoneal mucinous cystadenocarcinoma in a 38-year-old woman. STUDY DESIGN The tumor was resected with a segment of adjacent descending colon. Five years after the operation, the patient is well, without evidence of recurring disease, based on clinical investigation and modern imaging techniques. RESULTS In the light of the literature, it appears most likely that this rare tumor is caused by coelomic metaplasia. On the basis of the histopathologic findings in our case and the reports from the literature, we recommend radical tumor excision en bloc with all infiltrated adjacent structures. CONCLUSION Added removal of unaffected uterus and adnexes makes young women infertile and climacteric and is not yet validated by long-term results.

Abstract
CONTEXT Endometrioid carcinoma is often preceded by characteristic histopathologic lesions known as endometrial hyperplasia. Estrogen appears to be involved in the development of endometrioid carcinoma. Other mechanisms of endometrial carcinogenesis include mutations in p53 and PTEN tumor suppressor genes and overexpression of cyclin D1. However, the pattern of cyclin D1 expression is not well defined in normal, hyperplastic, neoplastic, and metaplastic endometrium. DESIGN Cyclin D1 immunohistochemical analysis was used to evaluate 108 fixed, paraffin-embedded endometrial biopsy specimens and uterine resections obtained from 108 patients. Specimens included proliferative and secretory endometria, simple and complex hyperplastic lesions, and endometrioid adenocarcinoma. Normal and metaplastic surface epithelia were also evaluated independently of glandular morphologic features. RESULTS Cyclin D1 was significantly overexpressed in glands with complex hyperplasia and endometrioid adenocarcinoma compared with proliferative or secretory endometrium and simple hyperplasia. Significant overexpression was also noted in papillary, syncytial, and squamous metaplasias compared with normal surface epithelium or epithelium with tubal metaplasia. CONCLUSION Overexpression of cyclin D1 increases from normal endometrium to hyperplasia and carcinoma, suggesting that it may play a role in endometrial carcinogenesis. Overexpression of cyclin D1 in endometrial glands was independent from overexpression of cyclin D1 in surface metaplastic epithelium.

Abstract
A wide range of epithelial and mesenchymal pseudoneoplastic disorders of the urinary bladder may clinically and pathologically mimic a malignant neoplasm. These lesions usually require a tissue biopsy for definitive diagnosis. It is important to be aware of these lesions and their spectrum of morphologic appearances to avoid overdiagnosis and inappropriate aggressive therapy.

Abstract
AIM Overexpression of p53 has been reported in endometrial carcinomas, especially in uterine papillary serous carcinoma (UPSC), to correlate with worse prognosis. Endometrial metaplasia is commonly encountered in patients with dysfunctional uterine bleeding (DUB) and may on occasion be difficult to distinguish from atypical endometrial hyperplasia or carcinoma on biopsies. The present study was initiated in the belief that metaplastic tissue might not show overexpression of p53 and would thus help to distinguish it from carcinomas of non-endometrioid histology. METHODS AND RESULTS Paraffin-embedded tissue of endometrial biopsies with papillary metaplasia (22 cases), tubal metaplasia (five cases) and eosinophilic meta-plasia (seven cases) from patients with DUB were immunostained for p53 immunoreactivity. No evidence of hyperplasia was noted in any of the cases selected for the study. Twenty-eight cases of UPSC were included for comparison. Our study showed p53 overexpression in 25 of 28 (89%) UPSC. Weak and heterogeneous p53 immunoreactivity was present in 10 of 22 (45%) papillary metaplasias, four of five (80%) tubal metaplasias and four of seven (57%) eosinophilic metaplasias. Follow-up of 16-45 (median 32) months was unremarkable except for one patient with eosinophilic metaplasia who had simple endometrial hyperplasia in subsequent biopsy. CONCLUSIONS The presence of weak and heterogeneous p53 immunoreactivity in metaplastic endometrium is unexpected and might be a consequence of DNA damage. Intense, diffuse and homogeneous p53 staining favours carcinoma.

Abstract
Strong epidemiological evidence links human papilloma viruses (HPV) with the development of cervical intraepithelial neoplasia (CIN) and invasive cancers of the uterine cervix. The localization of HPV DNA sequences high up in the female genital tract (in benign and malignant lesions) is not that uncommon, but its precise significance is uncertain. In particular, the detection of HPV DNA sequences by polymerase chain reaction (PCR) needs careful interpretation, because the source of the amplicon may emanate from tumor cells, direct contamination from the cervix, or possibly from extratumoral sites in the endometrium. We have previously reported the identification of koilocyte-like changes in the squamous epithelium of some endometrial adenoacanthomas. Adenoacanthomas (adenocarcinoma with squamous metaplasia) are mixed epithelial tumors arising in the endometrium composed of malignant glandular areas admixed with benign metaplastic squamous epithelium. The rarer adenosquamous carcinoma containing both malignant glandular and squamous areas is also described. The origin of benign/malignant squamous epithelial islands in endometrial tumors has been the subject of speculation, with some investigators considering an origin from metaplastic glandular endometrial cells. In this study, we examined 10 normal endometrial samples, 20 adenocarcinomas, 41 adenocarcinomas with squamous metaplasia, and two adenosquamous carcinomas, (including control cervical material where possible) for the presence of HPV DNA sequences using nonisotopic in situ hybridization (NISH), type-specific HPV PCR, general primer PCR (to detect sequenced and unsequenced HPVs), and PCR in situ hybridization (PCR-ISH). We did not identify HPV DNA sequences in normal endometrial tissue. In adenocarcinomas (endometrioid type), HPV was only identified in 2 of 20 cases by PCR, both of which were HPV 11 positive. We were unsuccessful in identifying HPV in endometrial carcinomas by NISH or by PCR-ISH, raising the possibility of contamination from the cervix in the two positive cases. In adenoacanthomas, a low-risk HPV type (HPV 6) was found in 19 of 41 cases. NISH signals were intranuclear in location in squamous regions of adenoacanthomas. Additional positive nuclei were uncovered using PCR-ISH, which increases the sensitivity of standard NISH detection. HPV DNA sequences were located in some malignant endometrial glandular epithelial cells, but this accounted for a minority of samples. HPV DNA sequences were not detected in extraepithelial sites. Mixed infection by two different HPV types was identified in two cases. Most cases showed similar HPV types in cervical and endometrial lesions, although discordant cases were uncovered. In adenosquamous carcinomas, one case showed mixed infection with HPV 6 and 33 by PCR. The apparent segregation of low-risk HPV type (HPV 6) with benign squamous metaplastic epithelium in adenocarcinoma with squamous metaplasia, and high-risk type (HPV 33) with malignant squamous epithelium in adenosquamous carcinoma, raises important questions in relation to the role of HPVs in mixed epithelial tumors of the endometrium and their interplay in the pathogenesis of squamous metaplasia at extracervical sites.

Abstract
Pathologists confront questions concerning the clinical implications of the more complex, evolving histopathologic classification in cervical carcinoma with glandular differentiation (CCGD) and the associated precursor intraepithelial lesions. Pseudoneoplastic pitfalls, such as microglandular hyperplasia, constitute the subject of recent reports, but the extent of misinterpretation for CCGD is unknown. To address these issues, we retrospectively reviewed all the histopathologic material for 67 patients treated for early clinical stage (I or II) CCGD. Two patients (3%) had pseudoneoplastic glandular lesions (two microglandular hyperplasias). The remaining 65 CCGDs included 35 pure adenocarcinomas (18 mucinous, six serous, five endometrioid, five clear cell, and one adenoid cystic), 26 adenosquamous carcinomas (17 showed > or = 50% and nine showed > 10% but < 50% squamous differentiation-all nonkeratinizing; four were predominantly glassy cell type, and the others showed the following adenocarcinoma component differentiation: 11 mucinous, eight serous, and three endometrioid) and four villoglandular papillary adenocarcinomas (all four were mucinous). In situ carcinoma was identified in 54%. The two patients with pseudoneoplastic lesions were disease free (after 96 and 108 months). Twenty-one patients with CCGD had recurrent disease at 4 to 144 months (mean, 45; median, 18) including three local recurrences, 10 with distant metastasis, and eight with both. Thirty-five patients with CCGD were disease free at 12 to 216 months follow-up (mean, 80.6; median, 65). Adenosquamous (P < .0002, predictive value [PV] = .68) and serous differentiation (P < .05, PV = .61) were the only histological types associated with disease recurrence. Vascular space invasion (P < .0002, PV = .7), deeper invasion (P < .0005), nuclear grade (P = .002, PV = .51), larger tumors on clinical exam (P < .01) or pathological evaluation (P < .01), and presence of pelvic lymph node metastasis at surgery (P < .05, PV = .7) are additional features associated with recurrent disease. A combination of adenosquamous or serous differentiation and vascular space invasion maximized PV for recurrent disease at a level of .75. Mucinous, endometrioid, or clear cell histological types, architectural grade, or the distinction between clinical stages I and II were not associated with recurrent disease. None of the four patients with villoglandular papillary adenocarcinoma exhibited recurrent disease, but confirmation of this histological subtype's prognostic value was hindered by the small number of cases identified (P = .16). Adenosquamous and serous differentiation, nuclear grading, pathological evaluation of vascular space and lymph node involvement, and recognition of pseudoneoplastic glandular lesions helped predict recurrent disease in low clinical stage CCGD in this retrospective study.

Abstract
A case of endometrial ciliated carcinoma mixed with foci of mucinous adenocarcinoma and argyrophil cells is described. The patient suffered from diabetes mellitus, hypertension and obesity, but had no history of estrogen use. Although the tumor presented well differentiated histologic features, it showed complete diffuse, endophytic extension. Approximately half of the cilia had abnormal inner structures, with 8 + 2 microtubular pattern. Some ciliated cells contained intracytoplasmic mucin, while others contained neurosecretory granules. These findings suggest that malignant ciliated cells have the capacity of further transformation into mucinous or endocrine cells.

Abstract
Apocrine differentiation was an incidental finding in an ovarian cyst. This is considered to be a further example of Müllerian metaplasia that has not been described before and which, theoretically, could occur in any organ of Müllerian derivation (ovary, uterus, cervix or fallopian tube). It is suggested that sites of such metaplasia could in turn be the origin of primary apocrine carcinoma in any of the above locations.

Abstract
Poorly differentiated Sertoli-stromal cell tumors and carcinosarcomas of the ovary both show biphasic epithelial and stromal patterns and may both show heterologous stromal elements, presenting a difficult diagnosis. We studied the immunohistochemical profile of Sertoli cell differentiation in human testes and applied these findings to the ovarian tumors. Eleven Sertoli-stromal cell tumors, six carcinosarcomas of the ovary, and 11 testes (six fetal, one infant, and four adult) were studied using antibodies to cytokeratin AE1:AE3 (AE1:3), cytokeratin CAM 5.2 (CAM), epithelial membrane antigen (EMA), vimentin, desmin, muscle-specific actin (MSA), S-100 protein (S-100), CA 19-9, CA 125, carcinoembryonic antigen monoclonal (CEA-M), carcinoembryonic antigen polyclonal (CEA-P), and placental alkaline phosphatase (PLAP). In the fetal testes, immature gonadal stroma and sex cord areas stained with vimentin (six of six cases), AE1:3 (five of six cases), and CAM (six of six cases). Sertoli cells in immature gonadal stroma areas, sex cords, and seminiferous tubules of normal fetal, infant, or adult testes never showed immunoreactivity for EMA, S-100, CA 19-9, CA 125, CEA-M, CEA-P, or PLAP. All Sertoli-stromal cell tumors stained with AE1:3 and CAM in areas of Sertoli cell differentiation (11 of 11 cases) but did not stain with EMA, PLAP, CEA-P, CEA-M, CA 19-9, CA 125, or S-100 (none of 11 cases). Carcinosarcomas expressed AE1:3 and CAM in all epithelial areas (six of six cases) and most stromal areas (five of six cases). Carcinomatous areas of carcinosarcoma also showed immunoreactivity for EMA (six of six cases), CA 125 (two of six cases), PLAP (two of six cases), CEA-P (two of six cases), and CEA-M (one of six cases), while stromal areas of carcinosarcoma expressed EMA (four of six cases) and S-100 (four of six cases). Heterologous stromal elements were present in three of 11 Sertoli-stromal cell tumors (two showed skeletal muscle and one showed both skeletal muscle and cartilage differentiation) and in four of six carcinosarcomas (one skeletal muscle, one cartilage, and two cartilage and skeletal muscle). All skeletal muscle heterologous elements expressed desmin, vimentin, and MSA. The heterologous cartilage in carcinosarcoma stained with S-100 (three of three), while the one case of heterologous cartilage in Sertoli-stromal cell tumor did not. These results suggest that ovarian Sertoli-stromal cell tumor can be distinguished from carcinosarcoma by the absence of staining for EMA, PLAP, CEA, CA 125, or CA 19-9 in epithelial areas of Sertoli-stromal cell tumor.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
We examined the cervicovaginal cytology (PAP) findings in a series of 21 endometrial and 2 cervical carcinosarcomas (CS) [malignant mixed mullerian (mesodermal) tumors] (MMMT). Initial cytology diagnosis was positive for cancer in 14 of 23 cases (sensitivity of 61%); however, CS was correctly identified only 2 times. The remaining 12 cancer diagnoses were carcinomas: 10 adenocarcinomas (4 endometrial, 1 cervical, and 5 adenocarcinomas not otherwise specified), 1 squamous carcinoma, and 1 poorly differentiated carcinoma. Seventeen smears were available for review, all 8 false negative, one unsatisfactory, and 8 of 14 true positive smears. One false negative smear showed rare clusters diagnostic of adenocarcinoma. The remaining 7 false negative smears showed 3 high grade squamous dysplasias (two with additional findings: one showed atypical spindle cells and the other showed endometrial stromal cells), 2 extensive repair changes, and 2 negatives. The unsatisfactory smear showed atypical spindle cells. Review of the 8 true positive smears confirmed malignant spindle cells in the two cases originally identified as CS by cytology and in 3 other cases originally identified as adenocarcinoma. Of 9 smears positive for cancer available for review, 4 showed only carcinoma cells. PAP positive for cancer was associated with high stage at presentation (P less than .025) and recurrent disease (P less than .001) (even among stage I or II patients, P less than .025). PAP positive for cancer showed no association with depth of myometrial invasion, size, grade, or histologic type of carcinosarcoma. The results of this study demonstrate the importance of consultative cytology reporting in which recommendations for appropriate biopsy are included in the report.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Two patients with primary squamous cell carcinoma of the uterus are described. In both patients, the disease was at an advanced stage when the diagnosis was made. Although endometrial malignancies with squamous elements account for 10-30% of endometrial carcinomas, primary squamous cell carcinoma of the uterus is extremely rare. Up to now fewer than 30 cases have been reported. The pathogenesis, morphogenesis and aetiology of squamous epithelium in the corpus uteri is discussed. Finally, some clinical aspects of the primary squamous cell carcinoma of the corpus uteri are reviewed.

Abstract
The observation of koilocyte-like features in the squamous epithelium of some endometrial adenoacanthomas prompted an investigation into a possible viral aetiology. These changes closely resemble those that occur in the ectocervical mucosa which are accepted as morphological evidence of human papillomavirus (HPV) infection. Sections of 87 hysterectomy specimens removed for endometrial carcinoma over 12 years, together with preoperative curettings, were reviewed for the presence of acanthomatous change and for appearances suggestive of HPV infection. The ages of the women ranged from 36 to 84 years, average age 62.6. Light microscopical examination showed koilocytosis, papillary formations, and intranuclear eosinophilic inclusions of both squamous and glandular epithelium in some tumours. Immunocytochemistry and DNA in situ hybridisation indicated the presence of HPV antigen in squamous and glandular cells, and perinuclear virus particles characteristic of HPV were seen on electron microscopical examination in those cells with nuclear inclusions. HPV probably infects endometrial adenocarcinomas directly from the cervix but it is unlikely that it has an aetiological role. It is possible, however, that in addition to being a "passenger," the virus may stimulate squamous metaplasia in some adenocarcinomas of the endometrium and may also exert some influence on their behaviour.

Abstract
A mucinous cystadenoma of the mesentery and two borderline mucinous cystadenocarcinomas of the mesentery and retroperitoneum are reported. The patients were females, aged 38, 47 and 58 years. The cysts showed identical features to those commonly seen in the appendix and ovary. One of our cases, with 'borderline' histology, developed metastases to mediastinal lymph nodes, 4 years after diagnosis. We suggest that these tumours develop through mucinous metaplasia in pre-existing mesothelium-lined cysts, the latter being the commonest cysts in this location.
