Abstract
Objectives Atypical glandular cells (AGC) detected by Papanicolaou (Pap) smears are in close relation with adenocarcinoma and precursors detected by histopathology. Yet, sometimes the cytological diagnosis of AGC has been neglected. With increase of adenocarcinoma and precursors, we need more focus on glandular abnormalities. Material and Methods Clinicopathological data of patients who had AGC on Pap smears between April 2015 and October 2018 and underwent histological follow-up were retrieved from the computerized database of Beijing Obstetrics and Gynecology Hospital, Capital Medical University. Patients with a prior history of cancer were excluded from the study. Statistical analyses were performed using Pearson's Chi-square test in SPSS software version 23. P < 0.05 (two sided) was considered as statistical significance. Results Liquid-based cytological examination of the uterine cervix was carried out in 164,080 women. Five hundred and twenty-five women were diagnosed with AGC, 314 with not otherwise specified (AGC-NOS), and 211 with favor neoplastic (AGC-FN). Only 310 cases had histological follow-up, 168 women (168/314, 53.5%) originally with AGC-NOS on Pap smears, and 142 (142/211, 67.3%) with AGC-FN. The median age of histological significant abnormalities was 46.7 years, and 126 women (126/162, 77.8%) were postmenopausal. Sixty-six cases (66/168, 39.3%) of AGC-NOS had significant abnormalities (96/142, 67.6%, AGC-FN). One hundred and sixty-two cases of significant abnormalities included 40 high-grade squamous abnormalities and 122 glandular abnormalities. AGC-FN was more likely to be associated with a clinically significant abnormalities (P < 0.001) compared to AGC-NOS. Conclusions Patients with AGC on Pap smears are in close relation with significant abnormalities, especially with significant glandular abnormalities on histopathology slices. AGC should be evaluated vigilantly with histological workup, especially if patients are diagnosed with AGC-FN and are aged 41-60 years. We need more focus on AGC.

Abstract
OBJECTIVES The objective of the study was to determine the prevalence and clinical significance of atypical glandular cells (AGC) or atypical glandular cells of undetermined significance (AGUS) diagnosed in pregnant and postpartum women. STUDY DESIGN Smears having a diagnosis of AGC or AGUS, taken from pregnant and postpartum (within six weeks after delivery) women between 1995 and 2008 were reviewed and subclassified according to the Bethesda 2001 classification. Case records were then reviewed and a second cytology review was performed after disclosure of the follow-up data. RESULTS Among 91,133 smears taken from pregnant and postpartum women, 70 had AGC or AGUS (0.07%) diagnosed. Follow-up data were available in 40 cases, with mean duration of follow-up being 43 months. Among the 40 patients with follow-up data, nineteen had smears with coexisting squamous abnormalities. Thirty patients had positive pathology, including 18 (45%) cervical intraepithelial neoplasia III (CIN III), four (10%) cervical adenocarcinoma-in situ, three (7.5%) squamous cell carcinoma of cervix, four (10%) condylomas and one (2.5%) hydatidiform mole. On review, 24 out of 32 smears with AGC 'not otherwise specified' ('NOS') had significant pathology. CONCLUSIONS AGC found on cervical smears during pregnancy and the postpartum period is uncommon. The chance of having significant cervical pathology, however, is high and colposcopy should be performed.

Abstract
BACKGROUND Atypical glandular cell (AGC) on Pap smear is uncommon but may represent a variety of benign and malignant lesions. AIM The aim of this study was to evaluate the association between AGC on Pap smear and significant pathological finding to tailor management protocols. METHODS Between 2002 and 2005, 60 women with AGC on Pap smears were referred to our colposcopy clinic. Forty-one women underwent colposcopy-directed biopsy, endocervical curettage, endometrial sampling and cervical conisation to determine the cytological and histological correlations of AGC on Pap smears. RESULTS The mean age of the patients was 46.9 +/- 11.5 years (range, 23-80 years). Of these patients 13 patients (31.7%) were postmenopause and 28 patients (68.2%) were in reproductive age. We found eight (19.5%) significant pathological findings including four (9.7%) high-grade squamous intraepithelial lesion, one (2.4%) adenocarcinoma of uterus, one (2.4%) adenocarcinoma of cervix, one (2.4%) squamous cell carcinoma of cervix and one (2.4%) papillary serous tumour of ovary. CONCLUSION AGC on Pap smear was associated with a clinically significant diagnosis in approximately 20% of our cases. The women with a diagnosis of AGC on cervicovaginal smear are needed to be evaluated at least with colposcopy, endocervical and endometrial curettage. Clinicians should be careful about the significance of AGC on Pap smears.

Abstract
OBJECTIVE To evaluate the presence of some criteria in cervical smears with atypical glandular cells and their correlation with histological patterns to identify pre-neoplastic and neoplastic lesions. METHODS Seventy-three women referred with an atypical glandular cell smear, who had undergone conization or hysterectomy, were included in this study. Referral Pap smears were reviewed using the set of 27 cyto-morphological criteria that was correlated with the histological diagnosis. RESULTS Histological results showed intraepithelial or invasive neoplasia in 35 (48%) cases and benign lesions in 38 (52%) cases. After logistic regression and decision tree analysis an increased nuclear/cytoplasmic ratio and the presence of dyskeratotic cells were strongly associated with intraepithelial or invasive neoplasia and the differential cyto-morphological criteria for glandular lesions were decreased cytoplasm, irregular nuclear membranes and the presence of nucleoli. CONCLUSION The analysis of individual cyto-morphological criteria can better predict intraepithelial or invasive neoplasia and differentiate glandular from squamous lesions.

Abstract
This article is to determine the clinical significance and underlying pathology among patients with atypical glandular cells (AGC) identified during cervical Papanicolau (Pap) smear screening. AGC slides were searched from 51,412 computerized files of the cytology laboratory of Mackay Memorial Hospital during a 29-month period. The results of clinical evaluations were reviewed and an experienced gynecologic cytopathologist who was not involved in the original cytologic diagnosis and was not aware of the clinical results of the follow-up examinations rechecked all AGC slides. We used the z score to determine whether different results were achieved after the gynecologic cytopathologist rechecked the slides. We further analyzed all slides with different cytologic diagnoses and compared results with the histologic diagnoses. Forty-nine cases were initially identified as AGC. Among these, 29 were reviewed and identified as AGC again, and the result of biopsies revealed that they were all chronic cervicitis, ie, negative for malignancy or premalignancy. The other 20 cases were reviewed and diagnosed as non-AGC. Among the results of cytologic examinations, seven had inflammation, two had atypical squamous cells of undetermined significance (ASC-US), ten had high-grade cervical intraepithelial neoplasia (CIN), and one had adenocarcinoma. The results of histologic diagnosis included eight cases with normal tissue, two with CIN grade 1, eight with high-grade CIN, one with microinvasive squamous cell carcinoma, and one with adenocarcinoma. Histologic results revealed 20.4%1 (10/49) and 50% 1(10/20) at initial cytologic diagnosis of AGC and expert-reviewed non-AGC, respectively, which were finally at least high-grade CIN. According to the gynecologic cytopathologist's diagnosis, 59.2%1 (29/49) of cases would have eliminated unnecessary histologically diagnostic procedures. In conclusion, clinicians should be careful about the significance of the cytologic diagnosis of AGC, because there may actually be an underlying pathology, which can be identified by a pathologist who is an expert in gynecologic cytopathology. The interobserver variation in diagnosing AGC favors specialized training in gynecologic cytopathology. In addition, prompt diagnostic interventions, including colposcopy, endocervical curettage, and/or endometrial biopsy, should be performed after confirmation of the diagnosis of non-AGC by an experienced gynecologic cytopathologist.
