Abstract
BACKGROUND Exfoliated endometrial cells can be seen in cervical smears in association with a wide variety of conditions ranging from normal proliferative endometrium to endometrial malignancies. It is often difficult to differentiate between benign, atypical and malignant endometrial cells using cytomorphology alone. This study was conducted to evaluate if morphometric analysis of endometrial nuclei on liquid-based cervical samples could be of help in differentiating between these endometrial cells. MATERIALS AND METHODS Three groups of cervical samples with histopathological correlation were selected: Group A: showing benign endometrial cells; Group B: showing atypical endometrial cells and Group C: showing malignant endometrial cells. There were 30 cases each in Group A and B and 39 cases in Group C. Image J, NIH, USA was used for selecting the endometrial nuclei and performing the morphometric measurements. MANOVA was used for statistical analysis. RESULTS The mean nuclear area and nuclear perimeter were significantly different between the three groups of endometrial cells with a P-value <0.05. However, the mean standard deviation of the nuclear area (SDNA) was not significantly different between atypical and malignant endometrial cells (P = 0.765) and the mean nuclear diameter was not statistically different between benign and atypical cells (P = 0.112). Also, the difference in the mean integrated gray density amongst all three groups was not statistically significant (P = 0.397, 0.844, 0.732). CONCLUSION We conclude that the morphometric parameters of the nuclear area and nuclear perimeter are helpful in differentiating between benign, atypical and malignant endometrial nuclei even in liquid-based cervical cytology samples.

Abstract
We studied 1,183 Papanicolaou (Pap) cytology cases (739 with normal endometrial cells [nEMCs], 423 with atypical EMCs [aEMCs], and 21 with endometrial cancer cells [EMCCs] in women 40 years or older) with histologic follow-up. Significant endometrial lesions were found in 2.7%, 18.4%, and 100% of cases with nEMCs, aEMCs, and EMCCs, respectively. Significant lesions were present in women 50 years or older with nEMCs found after day 12 of the menstrual cycle or who were postmenopausal (5.2%), but not in women with nEMCs before day 12 (0.5%) or women younger than 50 years with nEMCs after day 12 (1.6%). Our data indicate that endometrial sampling provides no clinical benefit in women (regardless of age) with nEMCs before day 12 of the menstrual cycle or women younger than 50 years with nEMCs after day 12. Endometrial sampling should be routinely performed in women with aEMCs and in women 50 years or older with nEMCs after day 12 of the menstrual cycle or who are postmenopausal.

Abstract
In this study, the role of cervical cytology in the diagnosis of post or perimenopausal (PM) bleeding was explored. A total of 135 patients with PM bleeding were selected. In all these cases both conventional cervical cytology and histopathology follow up were available. The commonest causes of postmenopausal (PM) bleeding with abnormal histopathology were squamous cell carcinoma of cervix (14), endocervical polyp (13), endometrial adenocarcinomas (13) and simple hyperplasia without atypia (13). There were a total 13 cases of endometrial adenocarcinoma and cervical smears of these cases were reported as high grade squamous intra epithelial lesion (1), presence of endometrial cells (4), unsatisfactory due to low cellularity (2), and within normal limit (6). In brief, endometrial carcinoma and hyperplasia are the predominant causes of PM bleeding due to endometrial pathology. The presence of benign looking endometrial cells with PM bleeding always indicates a careful work upto exclude endometrial pathology.

Abstract
OBJECTIVE The 2001 Bethesda System consensus statement directs the reporting of endometrial cells on cervical cytologic preparations in women aged 40 years or older. Our objective was to assess the significance of endometrial cells on cervical liquid-based cytology (LBC) specimens in this population. METHODS The population included women aged 40 years or older in whom endometrial cells were identified in otherwise normal LBC specimens from December 2001 through June 2005, and who subsequently underwent endometrial sampling within a 12-month period. Patient age, menopausal status, hormonal use, the presence or absence of co-incident symptoms and endometrial sampling results were recorded. RESULTS Endometrial cells were identified on LBC specimens in 2494 women during the study period, for an incidence of 0.4%. Of these, 370 women underwent endometrial sampling within 12 months of the incident LBC preparation and met inclusion criteria. In asymptomatic premenopausal women, sampled solely due to the presence of endometrial cells, 2.1% were identified with significant endometrial pathology, compared to 2.6% of symptomatic premenopausal women. In menopausal women, only those with symptoms (mainly bleeding) had significant pathology on subsequent sampling (25%); none of the asymptomatic menopausal women were found to have hyperplasia or carcinoma. No significant differences were identified in premenopausal women according to the time of sampling during the menstrual cycle or use of oral contraceptives. CONCLUSION Endometrial cells on LBC preparations, even in the absence of symptoms in premenopausal women aged 40 years or older, are associated with significant uterine pathology.

Abstract
OBJECTIVE No consensus exists regarding evaluation of asymptomatic premenopausal women with benign endometrial cells (BECs) identified on cervical cytology. We determined the frequency of uterine pathology in asymptomatic women, > or = 40 years of age, positive for BECs on cervical cytology. STUDY DESIGN Cervical cytopathology records from a Midwestern US teaching hospital from April 2002 through December 2005 were reviewed and cases with BECs identified. Patient age, symptomatology, and endometrial sampling results were obtained. RESULTS Of 194,717 records examined, 1784 (0.9%) of women > or = 40 years had BECs present and 440 had follow-up endometrial pathology. There were 4 cases of complex hyperplasia with atypia, 2 from patients < or = 50 years, 1 was asymptomatic; 4 cases of adenocarcinoma were identified, all from women > 50 years. CONCLUSION To date, the present study is among the largest follow-up studies of women with BECs on cervical cytology. Follow-up endometrial sampling may not be indicated in asymptomatic patients < or = 50 years.

Abstract
BACKGROUND With the recent cervix screening national guidelines recommending against reporting of benign endometrial cells, we examined South Australian data to see what impact this would have on detecting uterine cancers. AIMS To test whether benign endometrial cells detected in cervical cytology testing confer an increased risk of uterine cancer, and to ascertain what percentage of uterine cancers will be missed in cervical screening programs if these cells are not reported. METHODS The study was a retrospective cohort design of 1585 women with shed endometrial cells, each matched with three women without shed cells. All were linked with cancer registry data to check for uterine cancer diagnosis. Cox proportional hazards regression was used to check for any increase in cancer risk with shed endometrial cells. Using the calculated relative risks for uterine cancer diagnosis, we estimated the number of uterine cancers in South Australia associated with benign endometrial cells. RESULTS The presence of benign endometrial cells in a cervical cytology test increases the risk of uterine cancer sixfold. However, screening women with benign cells would involve a major increase in pathology work for only an 18% increase in uterine cancers detected. CONCLUSIONS Until cytology systems have a higher sensitivity in detecting which benign endometrial cells are associated with uterine cancer, pathology laboratories are unlikely to be required to report these cells on tests. Inability to adjust for symptomatic status may have reduced the relevance of the results in this study.

Abstract
The objective of this study was to determine whether postmenopausal asymptomatic women with normal endometrial cells in their smear are at higher risk for endometrial pathology compared with women without these cells. Histologic follow-up outcome and otherwise cytologic follow-up of 29,144 asymptomatic postmenopausal women was determined. Presence of normal endometrial cells, age, use of hormones, and reported elevated maturation index were assessed. The effect of each variable on outcome as well as the combined effect were evaluated. Prevalence rate of (pre)malignant uterine disease was significantly higher when normal endometrial cells were found in the cervical smear (6.5%) as compared to smears without these cells (0.2%), resulting in a relative risk of 40.2 (95% CI 9.4-172.2). Neither age nor hormone use or elevated maturation index showed significant impact on the outcome. Asymptomatic postmenopausal women with normal endometrial cells in their smear are at significant higher risk for (pre)cancerous endometrial lesion than women without these cells. These cases should be reported to the physician with an explicit comment that normal endometrial cells in a smear of a postmenopausal woman is an abnormal finding, possibly associated with significant endometrial pathology. It raises the question whether further gynecological examination would be more appropriate.

Abstract
The 2001 Bethesda System for Reporting Cervical Cytology recommends reporting benign exfoliated endometrial cells in women age 40 and older, and a review of the literature supports this recommendation. Stromal cells and histiocytes do not need to be reported. The effect of hormonal therapy on endometrial shedding is reviewed. Clinical information should be provided to the laboratory so that appropriate educational notes can be appended to the cytology report. Benign endometrial cells in premenopausal women in the first half of the cycle are not associated with significant pathology and such women do not need additional evaluation. Significant pathology is also unlikely in the second half of the cycle and evaluation may not be required unless clinically indicated. Initial evaluation of other women with benign endometrial cells may include either endometrial sampling or transvaginal ultrasound. Atypical endometrial cells are associated with a higher rate of significant pathology and should lead to additional evaluation. Additional prospective studies on the management of patients with endometrial cells on Pap tests are needed.

Abstract
BACKGROUND The 2001 Bethesda System (TBS 2001) introduced a new diagnostic category-normal endometrial cells in women age 40 years or older (EM >or= 40). The objective of the current study was to determine whether there was any significant increase in the frequency with which this diagnosis was reported after the implementation of TBS 2001 and the clinical significance of this diagnosis. METHODS All women who had a Papanicolaou (Pap) test and a diagnosis of EM >or= 40 between January 1999 to December 2003 were identified. Follow-up included repeat Pap tests and/or surgical pathology. TBS 2001 was implemented on January 1, 2002. RESULTS In total, 556 Pap tests with a diagnosis of EM >or= 40 were identified, accounting for 0.52% of the 106,204 Pap tests evaluated during the study period. The incidence of EM >or= 40 before and after implementation of the new TBS was 0.47% and 0.61%, respectively, and showed a statistically significant difference. One hundred four patients (19%) underwent endometrial tissue sampling, including 22 patients who underwent hysterectomy (4%) and 82 patients who underwent endometrial biopsy (15%). Overall, 1 patient (2%) had significant endometrial pathology, namely, complex endometrial hyperplasia without atypia. CONCLUSIONS A significant increase in the incidence of EM >or= 40 was observed with the implementation of TBS 2001. However, there was no difference in the proportion of patients that underwent endometrial tissue sampling. In addition, the incidence of clinically significant endometrial lesions associated with such a diagnosis was very low. The authors recommend that women with benign endometrial cells on Pap tests in women age 40 years or older should undergo endometrial biopsy only when additional clinical indicators are identified.

Abstract
The success of the routine Papanicolaou (pap) smear in reducing the incidence and mortality of cervical cancer has been chronicled extensively. Unfortunately, endometrial cancer, the most common malignancy of the gynecologic tract, continues to lack a screening modality of comparable efficacy. It is generally accepted that the Papanicolau test has a low sensitivity for detecting endometrial disease. Nonetheless, it remains true that endometrial cells are not uncommonly identified on routine cervicovaginal smears and along with each case comes an associated responsibility for pathologists to assess cytologic features, assign a potential clinical significance, and make a decision on reporting this finding. When endometrial cells with an entirely normal cytologic appearance are identified on an otherwise unremarkable cervicovaginal smear, the central question raised is whether such cells are exfoliating physiologically or whether their exfoliation is pathologic in response to an underlying endometrial disease. Additionally, in the former scenario, could subsets of patients be defined in which the reporting of this finding is deemed unnecessary in the cytologic report? In this contribution, we explore the clinical significance of finding normal endometrial cells in cervicovaginal smears based on a review of the medical literature of the last half-century. The historical and evidentiary basis for the Bethesda 2001 recommendations, which calls for the reporting of cytologically benign endometrial cells only in patients 40 years and older, is reviewed in detail.

Abstract
BACKGROUND The 2001 Bethesda System recommends reporting benign endometrial cells (BECs) in women aged >or=40 years and considers these women at risk for endometrial pathology. The current study examines the relative risk of hyperplasia or malignancy conferred by the presence versus the absence of BECs in Papanicolaou (Pap) tests of women aged >or=40 years. METHODS Women aged >or=40 years represented 29,177 (46.2%) of 63,202 Pap tests obtained over 1 year from a largely suburban screened population. Of these, 866 Pap tests (3%) showed BECs. Over the same 1 year period, 789 women aged >or=40 years had endometrial histologic evaluations between 14 days and 6 months following a Pap test. The Pap tests of 159 women had BECs, and 33 had atypical (n=32) or malignant (n=1) endometrial cells. The 597 remaining women, who had Pap tests without endometrial cells but who had endometrial sampling for other reasons, served as controls. RESULTS There were nine endometrial hyperplasias (5.7%) and no adenocarcinomas in the BECs group, whereas 34 hyperplasias (5.7%) and 6 adenocarcinomas (1%) were diagnosed in the controls. These differences were not statistically significant, even after restricting the analysis to women aged >or=50 years or to women known to be postmenopausal. CONCLUSIONS The current study found that women aged >or=40 years with BECs in their Pap tests did not have more endometrial hyperplasias or malignancies when compared with women who had endometrial sampling for reasons other than the presence of endometrial cells in a Pap test.

Abstract
The 2001 Bethesda System has radically altered the classification of glandular abnormalities. The recognition of the cytologic features of atypical glandular cells on cervicovaginal smears is important because a significant number of patients will be found to have an underlying cancerous or dysplastic lesion of the exocervix, endocervix, or endometrium. The differential diagnosis of AGC on cytology is diverse and accurate classification is necessary because the most appropriate form of follow-up depends on the specific subcategorization of the atypical glandular cells. Because the level of interobserver agreement in the diagnosis of AGC is poor, effective communication between cytopathologists and clinicians is essential to accurately triage these patients. This article should help the cytology practitioner by providing a comprehensive review of the approach to the interpretation, clinical significance, histopathologic correlation, and management of patients who have atypical glandular cells on gynecologic cytology specimens.

Abstract
BACKGROUND The Bethesda System recommends reporting benign endometrial cells in cervical smears from postmenopausal (PMP) women as a glandular cell abnormality. However, PMP women on hormone replacement therapy (HRT) sometimes may experience endometrial shedding. The significance of such a finding has not been investigated in detail. METHODS The authors evaluated 85 PMP women with cervical smears that contained benign endometrial glandular cells. Clinical information, including vaginal bleeding and the use of HRT or tamoxifen, was recorded, and follow-up was obtained. RESULTS Thirty-three PMP women were not on HRT, and 11 women were symptomatic. Twenty women underwent endometrial biopsy: Two symptomatic patients had endometrial adenocarcinoma, and 3 symptomatic patients and 1 asymptomatic patient had endometrial polyps. The frequency of abnormal findings was 18%. Forty-seven PMP women received HRT; 15 were symptomatic. Twenty-two patients underwent endometrial biopsy: 1 symptomatic patient had cystic hyperplasia, and 2 symptomatic patients and 1 asymptomatic patient had an endometrial polyp. The frequency of abnormal findings was 8.5%. No one type of HRT was correlated with specific findings. Five PMP women were on tamoxifen, and two of them were symptomatic. Four patients underwent endometrial sampling: Two of them had an endometrial polyp, which was symptomatic in one patient. CONCLUSIONS These data confirm that benign endometrial glandular cells in cervical smears from PMP women may indicate endometrial pathology, especially if vaginal bleeding is present. Although atypical endometrial hyperplasia or carcinoma was not identified in the group of PMP women on HRT, endometrial abnormalities of a lesser degree were present in 8.5% of patients. Thus, the authors favor continued classification of benign endometrial glandular cells in cervical smears of PMP women, whether or not they are on HRT, as a glandular cell abnormality.

Abstract
This study assessed the significance of endometrial-type cells (ETC) in cervico-vaginal (CV) smears in patients 45 yr and older by evaluating quantitatively and qualitatively the relationship of ETC to subsequent endometrial pathology. In a 3-yr period (1997-1999) at the Johns Hopkins Cytopathology Laboratory, 1,162 CV smears with ETC were found in patients 45 yr and older. In all cases with positive follow-up by tissue biopsy/resection, i.e., endometrial hyperplasia (EHP) and endometrial adenocarcinoma (EACA), the CV smears were reevaluated and compared to the control group (i.e., patients with normal endometrial biopsies). The following cytologic characteristics were recorded: quantity of ETC, type of ETC (epithelial, stromal/histiocyte-type, or mixed), cellular atypism, presence of inflammation, smear background, and associated estrogen effect. Of the 1,162 patients with ETC, 432 cases (37%) had tissue follow-up as follows: EACA, 18 (4.2%); EHP, 20 (4.6%); leiomyomata, 17 (3.9%); endometrial polyp, 21 (4.9%); benign/within normal limits (WNL), 339 (78.5%); nondiagnostic, 17 (3.9%). Cytologic characteristics of ETC showed subtle but definite quantitative and qualitative differences in the major pathologic groups examined. All instances of cancers and hyperplasia occurred in postmenopausal (PM) women. Abnormal vaginal bleeding was the presenting complaint in 66.7% of EACA, 45% of EHP, and 28.6% of benign endometrium. ETC in PM CV smears are associated with significant endometrial lesions (carcinoma, hyperplasia) in less than 9% of the patients. It is concluded that the distinction between EACA and EHP can be difficult. The presence of a large number of ETC, predominantly of epithelial or a mixed (epithelial and stromal) type, is more often associated with EACA or EHP than with benign endometrium. The presence of cytologic atypia and/or diathesis is additionally helpful for the diagnosis of EACA.

Abstract
BACKGROUND The Bethesda System recommends qualifying atypical glandular cells with regard to their possible origin: endocervical versus endometrial. This study was undertaken to determine the clinical significance of atypical glandular cells of undetermined significance that favor an endometrial origin (AGUS-EM). METHODS A computer search identified 62 cervicovaginal smears (5.25% of all smears classified as AGUS) with a diagnosis of AGUS-EM in the files of Shared Cytopathology Laboratory of New York University Medical Center/Bellevue Hospital Medical Center between January 1995 and December 1999. The patients ranged in age from 29 years to 88 years (mean age, 53 years). Thirty-four patients were postmenopausal (55%), and 5 patients were on hormonal replacement therapy. Follow-up was available for 56 patients (90%); 45 patients (73%) underwent biopsy, and 11 patients (17%) had repeat cervicovaginal smears. Six patients were lost to follow-up. RESULTS Among patients who underwent biopsy, 14 patients (31%) had a clinically significant uterine lesions, including 6 (13%) endometrial adenocarcinomas, 5 (11%) endometrial hyperplasias, and 3 (7%) squamous lesions (2 high-grade squamous intraepithelial lesions and 1 squamous cell carcinoma). Ten of 11 patients with significant endometrial pathology findings were postmenopausal. The remaining 31 patients had benign pathology results, which included chronic cervicitis, endometritis, endometrial polyps, microglandular hyperplasia, and tubal metaplasia. Among the patients with repeat cervicovaginal smears, one patient had atypical squamous cells of undetermined significance; the remaining patients were within normal limits. CONCLUSIONS Approximately one-third of women with a diagnosis of AGUS-EM had a significant uterine lesion on subsequent biopsy; the majority of these lesions were endometrial in origin. Patients with a diagnosis of AGUS-EM on cervicovaginal smears should be followed closely, and endometrial curettage or biopsy should be included in their initial work-up.

Abstract
Our objective was to determine if the finding of benign endometrial cells on a Papanicolaou (Pap) smear of a postmenopausal woman is associated with endometrial/uterine pathology, independent of symptomatology and hormone replacement therapy (HRT) status. The medical records of 146 postmenopausal patients who had a Pap smear showing normal-appearing endometrial cells between January 9, 1997 and January 12, 2000 were reviewed. Uterine pathology for each patient was determined by reviewing the results of endometrial sampling (endometrial biopsy or dilatation and curettage), hysterectomy, or pelvic sonogram, which were performed within 24 mo of the cytologic smear. The results were then correlated with clinical symptomatology and HRT status of each patient at the time the cytologic smear was obtained. Of the 146 Pap smears coded with "endometrial cells in a postmenopausal woman," 50 were excluded due to prior hysterectomy, perimenopausal status, and absence of further follow-up. Of the remaining 96 women, 27 (28%) had benign pathologic findings including polyps, leiomyomata, and simple hyperplasia without atypia, whereas 11 (12%) had significant pathologic findings including hyperplasia with atypia, adenocarcinoma, mixed Mullerian tumor, and leiomyosarcoma. Of the 11 patients with significant pathology, only one patient did not have abnormal vaginal bleeding but instead had a 30-wk-size irregular uterus on examination, and only 2 patients received hormone replacement therapy. In conclusion, Reporting endometrial cells on Pap smears in postmenopausal women did not lead to the diagnosis of any cases of significant pathology that would have gone unsuspected clinically. Moreover, HRT status did not affect the incidence of normal endometrial cells on Pap smears in postmenopausal women, nor did it aid in distinguishing which postmenopausal women had endometrial/uterine pathology. This calls into question the usefulness of the current Bethesda guideline to report "benign endometrial cells in a postmenopausal woman."

Abstract
OBJECTIVE The aim of this study is to assess the significance of normal endometrial cells identified in screening Pap smears from asymptomatic postmenopausal women taking hormone replacement therapy (HRT). METHODS Endometrial histology reported from 93 asymptomatic postmenopausal women receiving HRT noted to have normal endometrial cells on a screening Pap smear was reviewed. Information regarding HRT, endometrial sampling, and interval between the sentinel Pap and sampling was extracted from the record. RESULTS Endometrial biopsies were obtained an average of 1.7 months after the Pap smears. Eighteen of the ninety-three histology specimens (19%, 95% CI: 12--27%) identified abnormalities, in four cases precancerous or cancerous lesions. These 18 abnormalities included 7 endometrial polyps; 7 cases of simple hyperplasia, 1 with atypia; 3 cases of complex hyperplasia, 1 with atypia; and 1 endometrial adenocarcinoma. CONCLUSION Normal endometrial cells identified on a screening Pap smear in this population may be an indication of endometrial disease.

Abstract
The objective of this study was to review a 5-year experience with atypical glandular cells of undetermined significance (AGUS) on Papanicolaou smear and to use the information to devise a triage method for patients presenting with this abnormality. Our Papanicolaou smear database was used to identify patients who were found to have AGUS results between January 1, 1994 and December 31, 1998. The medical records of these patients were reviewed for the results of follow-up studies, including repeat Papanicolaou smear, endocervical curettage, colposcopic directed biopsies, and endometrial biopsy. During the study period, 27,859 Papanicolaou smears were performed, with 306 (1.1%) being reported as AGUS; 18 patients had two AGUS smears. An additional 24 patients did not meet study criteria. The study group then consisted of 264 patients, of whom 244 (92.4%) reported for follow-up. There were 167 (63.3%) with atypical endocervical cells of undetermined significance (AECUS), 14 (5.3%) with atypical endometrial cells of undetermined significance, and 83 (31.4%) with AECUS plus a squamous cell abnormality. The overall prevalence of a high-grade squamous intraepithelial lesion (HSIL) was 11.8%. The prevalence of HSIL in the AECUS plus squamous cell abnormality group was 25.4%. None of the atypical endometrial cell group had HSIL. In the AECUS, favor dysplasia category, 29.4% had HSIL, whereas in the AECUS, favor reactive process or in unqualified, 2.3% had HSIL. Eighty-one patients underwent endometrial biopsy: three (3.7%) were found to have endometrial adenocarcinoma, and two (2.5%) had complex atypical endometrial hyperplasia. The prevalence of HSIL in patients with AECUS, favor reactive process or AECUS, unqualified Papanicolaou smears is low. Colposcopy is not necessary as an initial triage process for this category of patients. A significant percentage of patients with AECUS, favor dysplasia or AECUS with a squamous epithelial abnormality Papanicolaou smears have HSIL; this subset of patients should be investigated with colposcopy.
