Background: To determine the frequency of dysplastic lesions in the endocervical curettage (ECC) specimens of women with ASC-US and LSIL Pap and to evaluate the possible factors associated with high grade dysplasia in those ECC specimens. Materials and Methods: Two hundred and sixty patients with ASC-US and LSIL cytologic smears who underwent an ECC at the time of colposcopic examination during January 2010 and December 2012 were reviewed. Demographic and clinicopathologic data were collected. Multivariate analysis using binary logistic regression was used to identify factors that might be associated with high grade endocervical dysplasia. Results: The frequency of endocervical dysplasia was 7.7% (20 out of 260 patients). Cervical intraepithelial neoplasia (CIN) 1 and CIN 2-3 lesions in the endocervical canal were observed in 12 and 8 patients, respectively. No microinvasive or invasive cervical cancers were identified. There was no difference in the frequency of high grade endocervical dysplasia between the patients with satisfactory and unsatisfactory colposcopic examinations (1.4% vs 5.1%, respectively, p=0.087). A multivariate logistic regression analysis demonstrated a significant association between high grade CIN on ectocervical biopsy as well as LSIL cytologic smears and high grade dysplasia in endocervical canal (OR=0.046, 95%CI=0.007-0.288; p=0.001 and OR=0.154, 95%CI=0.025-0.942; p=0.043, respectively). Conclusions: The frequency of high grade endocervical dysplasia in women with ASC-US and LSIL cytologic smears was low. Therefore, routine performance of ECC in those women is debatable. High grade ectocervical dysplasia and LSIL cytologic smears may be used as predictors for high grade dysplasia in endocervical canal and ECC in these patients is reasonable.

We have investigated the cervicovaginal smears in order to define the cytologic features of uterine adenocarcinomas. Total 22 cases were reviewed(12 cases from the Sanggye Paik hospital, Inje university and 10 cases from the Korea Cancer Center Hospital) from January 1992 to December 1997. Five cases were endometrial adenocarcinomas and the remaining 17 cases were cervical adenocarcinomas. Seventeen cases of cervical adenocarcinomas were divided into endometrioid(6 cases), endocervical(7 cases), mixed endometrioid and endocervical(1 case), papillary (2 cases), and adenosquamous(1 case) carcinomas. The background of endocervical adenocarcinoma was hemorrhagic or inflammatory. The tumor diathesis was less prominent than that of the squamous cell carcinoma. The prominent features of the endocervical type adenocarcinomas were large and loose clusters, large intracytoplasmic vacuoles, and prominent overlapping and peripheral palisading of nuclei. In contrast, the endometrioid adenocarcinomas showed small and compact clusters, and small intracytoplasmic vacuoles. The detection rate of endometrial adenocarcinoma was lower than that of the endocervical adenocarcinoma.

45세 여자 환자에게 발생한 양성 자궁경부 용종이 골반 자기공명영상에서 악성 종양과 유사하게 보인 증례 보고이다. 자궁경부에 발생한 다방성 낭성 병변은 조영증강되는 고형 성분이 보였고 악성 가능성을 시사했다. 그러나 최종 병리학적 진단은 이 병변을 양성 자궁경부 용종으로 진단했다. 이 사례는 자기공명영상 소견만으로 자궁경부 병변을 진단하는데 한계가 있음을 지적하며, 양성 종양이 악성 종양과 유사하게 보일 수 있음을 보여준다.

Objective: To evaluate incidence of microbial growth from the tip of the embryo transfer catheter after embryo transfer in relation to clinical pregnancy rate following in-vitro fertilization and embryo transfer. Method: This study was performed prospectively at the time of transcervical embryo transfer following conventional in-vitro fertilization and intracytoplasmic sperm injection procedures. Sixty three patients were enrolled in this study. Microbiological cultures were performed on endocervical swabs and embryo transfer catheter tips. Results: Positive microbial growths were observed from endocervical swabs in 45 (71.4%) women and from catheter tips in 30 (47.6%) women. There was no statistically significant difference seen in the mean number of oocytes fertilized or number and grade of embryos transferred between the group of patients without growth and the group of patients with positive microbial growth from catheter tips. The clinical pregnancy rate were 30.3% in the group of patients without growth and 13.3% in the group with positive microbial growth from catheter tips. This difference in clinical pregnancy rates was statistically significant. Conclusion: Our finding is that microbial contamination at embryo transfer may influence implantation rates. The major questions arising from our finding are whether eradication of endocervical micro-organisms is possible and whether their eradication will improve implantation rates.

Small cell neuroendocrine carcinoma of the uterine cervix is a distinct subtype of cervical cancer that appears analogous to oat cell carcinoma and carcinoid tumors of the lung. It has been assumed to be derived from the neural crest via argyrophilic cells in the normal endocervix. We have recently encountered a case of small cell neuroendocrine carcinoma of the uterine cervix coexisting with adenocarcinoma which was argyrophil negative. A 66-year-old multiparous woman was admitted because of vaginal bleeding for 2 months. Cervicovaginal smear revealed several scattered clusters and sheets of monotonous small cells with some peripheral palisading in the background of hemorrhage and necrosis. Radical hysterectomy specimen revealed an ulcerofungating tumor on endocervical canal which was composed of two components. Major component of the tumor was made up of monomorphic population of small oval-shaped tumor cells arranged in sheets and partly in acinar structures or trabecular fashion. Other component was adenocarcinoma, endocervical well-differentiated type. Argyrophilia was present on the Grimelius stain and immunohistochemical studies revealed diffuse positivity to neuron-specific enolase and carcinoembryonic antigen. Electron microscopic examination showed clusters of small round to oval cells, which had a few well-formed desmosomes and several membrane-bound, dense-core neurosectetory granules.

Adenoma malignum is an extremely well-differentiated variant of cervical adenocarcinoma in which the cells composing the tumor lack the typical cytological features of malignancy. The prognosis of this rare tumor is poor in spite of high degree of differentiation. The cytologic characteristics are extremely bland so frequently make a confusion of adenoma mailgnum with endocervical glandular hyperplasia. We report a case of adenoma malignum in a 35-year-old woman who complained of mucoid vaginal discharge and vaginal bleeding. The cervicovaginal smear showed endocervical cells exhibiting a spectrum of atypical chances. The cells were arranged in multilayered strips and monolayered sheets. Individual cells ranged from cuboidal to columnar; typically the columnar cells had abundant lacy or vacuolated cytoplasm. The smear showed the majority of only atypical cells and small numbers of frankly malignant cells.

Purpose: To assess the success rates of two step loop electrosurgical excision procedure (LEEP) compared with conventional cold conization procedures for decreasing positive surgical margins. Materials and Methods: This study was conducted on 70 patients who underwent colposcopic evaluation in Zeynep Kamil Women and Children's Health Training and Research Hospital between 2013-2015 with indications of CIN 2/3 or persistent CIN 1 for more than 2 years. The study included age matched groups of patients with similar histopathololical lesions who underwent cold conization (n=40) or LEEP (N=30). Results: Comparison of tissue characteristics between the two groups revealed significantly higher deepest depth and lower volume of tissue removed by the two step LEEP. Ectocervical positivity rate was similar between groups (1/39 versus 0/29, P>0.05), while endocervical surgical margin positivity rate was significantly higher in the cold conization group (9/39 versus 0/29, P<0.05). Surgical margin positive cases were significantly older than the cases with negative margins (P<0.05). Conclusions: Two step LEEP made it easier to reach the squamocolumnar junction in the endocervical region with lower blood loss and applicability in office settings. Our study suggests to use two step approach in cases with high grade and glandular CIN.

Purpose: This study was conducted to assess the agreement and differences between cervical self-sampling with a Kato device (KSSD) and gynecologist sampling for Pap cytology and human papillomavirus DNA (HPV DNA) detection. Materials and Methods: Women underwent self-sampling followed by gynecologist sampling during screening at two primary health clinics. Pap cytology of cervical specimens was evaluated for specimen adequacy, presence of endocervical cells or transformation zone cells and cytological interpretation for cells abnormalities. Cervical specimens were also extracted and tested for HPV DNA detection. Positive HPV smears underwent gene sequencing and HPV genotyping by referring to the online NCBI gene bank. Results were compared between samplings by Kappa agreement and McNemar test. Results: For Pap specimen adequacy, KSSD showed 100% agreement with gynecologist sampling but had only 32.3% agreement for presence of endocervical cells. Both sampling showed 100% agreement with only 1 case detected HSIL favouring CIN2 for cytology result. HPV DNA detection showed 86.2%agreement (K=0.64, 95% CI 0.524-0.756, p=0.001) between samplings. KSSD and gynaecologist sampling identified high risk HPV in 17.3% and 23.9% respectively (p=0.014). Conclusion: The self-sampling using Kato device can serve as a tool in Pap cytology and HPV DNA detection in low resource settings in Malaysia. Self-sampling devices such as KSSD can be used as an alternative technique to gynaecologist sampling for cervical cancer screening among rural populations in Malaysia.

목적 : 자궁경부 선암종은 자궁경부 편평 세포 암종보다 림프절 전이와 국소적인 파급이 빨리 일어나고 5년 생존율이 낮으므로 임상적으로 선암종이 진단되었거나 의심될 경우에는 방바선학적 검사로 종양의 림프절 전이와 국소적인 파급을 세심하게 평가할 필요가 있다. 본 연구의 목적은 자궁경부 선암조의 자기공명영상(MRI) 소견을 분석하려 편평 세포암종과 다른 특징이 있는지 알아보는 데에 있다. 대상 및 방법 : 병리학적으로 확진된 자궁경부 선암종 환자 21명 중 MRI에서 종양이 관찰되는 18명(조직학적 병기 : Ib 10예, IIa 4예, IIb 2예, IIIa 1예, IIIb 1예)을 대상으로 그 MRI 소견을 후향적으로 분석한 후, 최근에 연속적으로 입원하여 편평 세포 암종으로 확진된 40명의 환자로 구성된 대조군과 비교하였다. 1.5T의 MRI기기로 조영 전후의 T1강조 및 급속 스핀 에코 T2 강조 영상을 축상 및 시상면에서 얻었다. MRI에 나타난 종양의 최대직경, 위치, 신호강도 및 조영증강정도, 윤곽, 형태, 상하 침범 범위, 동반 질환 유무 등을 분석하였다. 결과 : 자궁경부 선암종의 최대 직경은 0.8-4.1cm(평균 2.2cm)이었고, 이 종양이 경관내막을 따라 위치한 경우가 9예이었다. 모든 선암종의 신호 강도는 T1 강조 영상에서 주위 자궁경부 간질과 비슷하였고 급속 스핀 에코 T2 강조 영상에서는 높았다(균질성 10, 비균질성 8). 모든 선암종은 gadolinium 정맥 주입시 모두 조영 증강되었다(균질성 6, 비균질성 12 : 높은 신호강도의 고리 2). 선암종의 윤곽이 매끈한 경우가 8예이었고, 불규칙한 경우가 10예이었다. 선암종의 모든 예에서 자궁경부의 하부가 침범되었는데, 이중에서도 상부까지 침범된 경우는 6예이었다. 선암종 2예에서는 MRI상 직경 1.5cm 이상의 골반강 림프절들이 관찰되었고, 1예의 MRI에서는 림프절이 관찰되지 않았는데, 병리 검사상 모두 악성으로 판명되었다. 2예의 선암종에서 자궁 유수증이, 1예에서 자궁 유혈증이 동반되었다. 이상의 소견을 편평 세포 암종의 대조군과 비교하였을 대 선암종에서 경관내막형과 술통형이 더 많은 것이 통계학적으로 유의하였다. 결론 : 자궁경부 선암종은 편평 세포 암종에 비해 경과내막형, 술통형이 많은 MRI 소견을 보였다. MRI에서 자궁경부암의 모양이 경관내막을 따라 술통형이거나 병기가 낮은데도 주위 림프절로 파급되는 경향을 보이면, 자궁경부 선암종을 의심할 수 있을 것이다.

A case of primary non-clear-cell adenocarcinoma of the vagina is reported occurring in a 65-year-old woman without exposure to diethylstilbestrol (DES) in utero. The adenocarcinoma did not appear to be associated with vaginal adenosis. It lacked clear cell component and interestingly composed of columnar epithelial cells of endocervical-type. Cytologically round to oval nuclei revealed one or more small nucleoli and fine granular chromatin pattern. Cytoplasm was plump, faintly basophilic and homogeneously stained. Histologically well differentiated columnar epithelial cells were arranged on trabecular pattern mainly, and also occasional glandular lumina and small solid sheets were found. Mitoses were hardly found.
