Abstract
BACKGROUND Estrogen receptor (ER) testing performed using immunohistochemistry (IHC) is a critical predictive tool for breast cancer treatment. This study aimed to investigate the use of tonsil control for monitoring ER staining and hypothesize that optimal staining would reduce interlaboratory variations. METHODS A proficiency test for ER IHC was conducted using 21 tissue cores. The staining quality was centrally reviewed based on tonsil ER staining. RESULTS We found that 64.9% of participant samples demonstrated optimal or good staining quality. Poor staining quality was significantly associated with the use of Ventana autostainers and concentrated antibodies. Although the concordance rate did not show significant differences across staining quality levels, interparticipant agreement declined as staining quality deteriorated. Among the 19 discordant responses, 63.2% could be attributed to staining problems, whereas 36.8% could be due to misinterpretation. Poor staining quality due to inadequate staining was the primary reason for undercalls, which can lead to false-negative results. Misinterpretations of nonspecific faint staining that was weaker than the staining of the tonsil control were the cause of most overcalls. CONCLUSION Tonsil tissue is an ideal control for monitoring ER staining and can serve as a reference for determining the lower bound for ER positivity. Optimal ER staining and appropriate references for ER positivity can further improve ER IHC quality.

Abstract
The Asian Thyroid Working Group was founded in 2017 at the 12th Asia Oceania Thyroid Association (AOTA) Congress in Busan, Korea. This group activity aims to characterize Asian thyroid nodule practice and establish strict diagnostic criteria for thyroid carcinomas, a reporting system for thyroid fine needle aspiration cytology without the aid of gene panel tests, and new clinical guidelines appropriate to conservative Asian thyroid nodule practice based on scientific evidence obtained from Asian patient cohorts. Asian thyroid nodule practice is usually designed for patient-centered clinical practice, which is based on the Hippocratic Oath, "First do not harm patients," and an oriental filial piety "Do not harm one's own body because it is a precious gift from parents," which is remote from defensive medical practice in the West where physicians, including pathologists, suffer from severe malpractice climate. Furthermore, Asian practice emphasizes the importance of resource management in navigating the overdiagnosis of low-risk thyroid carcinomas. This article summarizes the Asian Thyroid Working Group activities in the past 7 years, from 2017 to 2023, highlighting the diversity of thyroid nodule practice between Asia and the West and the background reasons why Asian clinicians and pathologists modified Western systems significantly.

Abstract
Primary vaginal neuroendocrine tumours are extremely rare but aggressive. We report a case of primary poorly differentiated vaginal carcinoma with focal neuroendocrine differentiation. The clinical stage was cT3N1M0, FIGO stage III. The patient received six cycles of cisplatin-based concurrent chemoradiation therapy (CCRT) followed by six cycles of adjuvant chemotherapy (IEP protocol: ifosfomide, epirubicin and cisplatin). Pelvic MRI scans obtained after treatment completion revealed no residual tumour in the vagina. However, the patient experienced severe dyspnoea 2 months later. Chest X-ray revealed a reticulonodular interstitial pattern over bilateral lungs with suspicion of lymphangitic carcinomatosis. Further chest, abdominal and pelvic CT scans showed bilateral lung metastases with multiple mediastinal, left lower neck and left axilla, intra-abdominal and pelvic lymphadenopathies. For this rare tumour, cisplatin-based CCRT followed by IEP protocol adjuvant chemotherapy may have a limited treatment effect. Further studies are necessary to provide more information on clinical management.

Abstract
BACKGROUND The studies on the cytomorphologic features of NTRK-rearranged papillary thyroid carcinoma (PTC) are limited and some reported characteristics, such as frequent indeterminate diagnoses and presence of fibrotic fragments, are inconsistent in literature. METHODS NTRK gene rearrangements were detected in thyroidectomy specimens of PTC by either fluorescence in situ hybridization or next-generation sequencing. All the cytologic slides of NTRK-rearranged PTC were reviewed to evaluate the cytomorphologic features. The preoperative cytologic diagnoses of NTRK-rearranged PTC were compared with those of NTRK/BRAF wild-type and BRAFV600E -positive PTC. RESULTS Fourteen PTC cases were identified to harbor NTRK gene rearrangements. Most of them showed a mixed architectural pattern of cell fragments (n = 13, 92.9%) and microfollicles (n = 9, 64.3%) with relatively rare papillary structures (n = 4, 28.6%). Nuclear grooving was frequently present (n = 11, 78.6%) but was mostly subtle and limited. Seven cases (50.0%) showed rounded nuclei without discernible nuclear elongation, and only 3 (21.4%) cases presented with nuclear pseudoinclusions. Among these cases, 7 (50.0%) were diagnosed as The Bethesda System for Reporting Thyroid Cytopathology (TBS) category III, 2 (14.3%) were diagnosed as TBS IV, and 5 (35.7%) were diagnosed as TBS V. The rate of TBS III-IV diagnoses for NTRK-rearranged PTCs was significantly higher (64.3%) than that for the 25 consecutive NTRK/BRAF wild-type PTCs (20.0%, P = .013) and the 70 consecutive BRAFV600E -positive PTCs (7.1%, P < .001) as selected. CONCLUSIONS NTRK-rearranged PTC demonstrated intermediate nuclear features, such as subtle nuclear grooving, infrequent nuclear elongation, and rare pseudoinclusions, resulting in a significantly higher rate of TBS III-IV diagnoses compared to PTC with other molecular alterations.

Abstract
(1) Background: Accurate preoperative identification of medullary thyroid carcinoma (MTC) is challenging due to a spectrum of cytomorphologic features. However, there is a scarcity of studies describing the cytomorphologic features as seen on fine-needle aspiration (FNA) smears prepared using different staining methods. (2) Methods: We performed a retrospective study on MTC cases with available FNA slides from 13 hospitals distributed across 8 Asia-Pacific countries. The differences in the constitutive cytomorphologic features of MTC with each cytopreparatory method were recorded. A comparative analysis of cytologic characteristics was carried out with appropriate statistical tests. (3) Results: Of a total of 167 MTC samples retrospectively recruited, 148 (88.6%) were interpreted as MTC/suspicious for MTC (S-MTC). The staining methods used were Papanicolaou, hematoxylin-eosin, and Romanowsky stains. Seven out of the eleven cytologic criteria can be readily recognized by all three cytopreparatory methods: high cellularity, cellular pleomorphism, plasmacytoid cells, round cells, dyshesive cells, salt-and-pepper chromatin, and binucleation or multinucleation. An accurate diagnosis was achieved in 125 (84.5%) of the 148 samples whose FNAs exhibited five or more atypical features. Conclusions: The present work is the first study on MTC to compare the morphological differences among the cytologic staining techniques. We investigated the constitutive features and the reliability of diagnostic parameters. A feasible scoring system based upon cytomorphologic data alone is proposed to achieve a high degree of diagnostic accuracy.

Abstract
AIMS The aim of this study was to evaluate human epidermal growth factor receptor 2 (HER2) immunohistochemistry (IHC) in ovarian clear cell carcinoma (OCCC) by using two antibodies and two scoring guidelines in correlation with HER2 amplification and clinicopathological features. METHODS AND RESULTS A tissue microarray was constructed by use of a total of 71 OCCC cases for IHC (the A0485 antibody and the 4B5 antibody) and dual-colour silver in-situ hybridisation (DISH). Two pathologists independently scored the IHC according to the 2018 American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAP) breast cancer guidelines (breast guidelines) and the 2016 ASCO/CAP gastro-oesophageal adenocarcinoma guidelines (gastric guidelines). IHC concordances between A0485 and 4B5 were 87.3-93.0%. Three to 16 (4.2-22.5%) cases had an IHC score of 2+/3+ with frequent basolateral/lateral membranous staining. The 4B5 antibody yielded fewer IHC 2+ cases than the A0485 antibody (n = 2-6 versus n = 5-12). Five (7.0%) cases had HER2 amplification as determined with DISH. Cases with papillary-predominant growth patterns were significantly more likely to have HER2 amplification (P = 0.0051). In predicting DISH results, IHC scored according to the gastric guidelines yielded 100%/100% sensitivity and 83.3-95.5%/98.2-100% specificity, and IHC scored according to the breast guidelines yielded 60-80%/33.3-66.7% sensitivity and 95.5-100%/100% specificity (including/excluding IHC 2+ cases). One case had intratumoral heterogeneity, with discordant results between primary and metastatic tumour specimens. CONCLUSION We demonstrated HER2 amplification in 7% of OCCC cases, and the molecular change is significantly associated with papillary-predominant growth patterns. In predicting HER2 amplification, a combination of 4B5 IHC and gastric guidelines provides the best sensitivity and fewer equivocal (IHC 2+) cases. Given the intratumoral heterogeneity, assessment of HER2 status on whole tissue sections and on both primary and metastatic tumour specimens is recommended.

Abstract
Ovarian clear cell carcinoma (OCCC) is an aggressive chemotherapy-resistant cancer with limited treatment options, and some OCCCs have mismatch repair (MMR) deficiency (MMRD). Emerging evidence has revealed that various cancers with MMRD are susceptible to anti-programmed death-1/programmed death ligand-1 (anti-PD-1/PD-L1) immunotherapy, and certain histologic features are associated with MMRD. However, few studies have addressed this in OCCC. We reviewed 76 OCCCs for tumor-associated inflammation (intratumoral stromal inflammation and peritumoral lymphocytes) and performed immunohistochemistry for 4 MMR proteins and PD-L1. MMR-deficient OCCCs were analyzed for microsatellite instability (MSI), and those with MLH1 loss were tested for MLH1 promoter methylation. No patients fulfilled the Amsterdam II criteria for the diagnosis of Lynch syndrome. Four (5.3%) tumors showed diffuse intratumoral stromal inflammation obliterating the tumor-stroma interfaces, and none had peritumoral lymphoid aggregates. MMRD was found in 2 (2.6%) tumors; one had MLH1/PMS2 loss (MSI-high and MLH1 promoter methylation was detected) and the other had MSH2/MSH6 loss (MSI-low). Twenty (26.3%) tumors showed tumoral PD-L1 expression ≥1%. Both MMR-deficient tumors showed diffuse intratumoral stromal inflammation and tumoral PD-L1 expression ≥50%. Three of the 4 (75%) tumors with diffuse intratumoral stromal inflammation also showed tumoral PD-L1 expression ≥50%. None of the tumors without diffuse intratumoral stromal inflammation showed MMRD (P=0.021) or tumoral PD-L1 expression ≥50% (P=0.0001). We identified a strong correlation among diffuse intratumoral stromal inflammation, MMRD, and high tumoral PD-L1 expression in a small but significant subset of OCCCs. Histologic evaluation can facilitate patient selection for subsequent anti-PD-1/PD-L1 immunotherapy.

Abstract
BACKGROUND Assessing nuclear features is diagnostically challenging in the aspect of thyroid pathology. The aim of this study was to determine whether pathologists could distinguish BRAF-like and RAS-like nuclear features morphologically and identify morphological features to differentiate thyroid tumors with RAS-like mutations from encapsulated papillary thyroid carcinoma (PTC) with predominant follicular growth and BRAFV600E mutation. METHODS Representative whole slide images of 16 encapsulated thyroid tumors with predominant follicular growth were reviewed by 12 thyroid pathologists using a web browser-based image viewer. Total nuclear score was calculated from semi-quantitatively scored eight nuclear features. The molecular profile of RAS and BRAF genes was determined by Sanger sequencing. RESULTS Total nuclear score ranging 0 to 24 could differentiate BRAF-like tumors from RAS-like tumors with a cut-off value of score 14. The interobserver agreement was the highest for the assessment of nuclear pseudoinclusions (NPIs) but the lowest for nuclear elongation and sickle-shaped nuclei. NPIs were found in tumors with BRAFV600E mutation, but not in tumors with RAS-like mutations. Total nuclear scores were significantly higher for tumors with BRAFV600E than for those with RAS-like mutations (P<0.001). CONCLUSION Our results suggest that NPIs and high nuclear scores have diagnostic utility as rule-in markers for differentiating PTC with BRAFV600E mutation from benign or borderline follicular tumors with RAS-like mutations. Relaxation of rigid criteria for nuclear features resulted in an overdiagnosis of PTC. Immunostaining or molecular testing for BRAFV600E mutation is a useful adjunct for cases with high nuclear scores to identify true PTC.

Abstract
In Taiwan, thyroid fine-needle aspiration cytology is easily accessible and reliable for evaluating thyroid nodules. The sonographic pattern plays a major role and is the deciding factor for aspiration. We conducted a nationwide survey in 2017 and it revealed that 31% of laboratories had adopted The Bethesda System for Reporting Thyroid Cytopathology. There was a relatively high unsatisfactory rate (24.04%) and low rates of indeterminate diagnoses, including atypia of undetermined significance/follicular lesions of undetermined significance: 4.87%, and follicular neoplasm/suspicious for a follicular neoplasm: 0.35%. Moreover, the risks of malignancy in benign, atypia of undetermined significance, and suspicious for a follicular neoplasm were relatively high. These may reflect strict diagnostic criteria for indeterminate categories and better patient selection for surgery. Improvements in specimen sampling and continuing education programs are crucial. Newly-developed thyroid cytology technologies, such as immunocytochemistry, molecular testing, and computerized cytomorphometry, may further facilitate cytology diagnoses.

Abstract
BACKGROUND The accurate preoperative identification of medullary thyroid carcinoma (MTC) is challenging due to the rarity of tumor and variable cytologic appearance. The Asian experience with diagnosing MTC by fine-needle aspiration (FNA) was scarcely reported. METHODS Cases of MTC with available FNA slides were enrolled from 13 hospitals representing 8 Asia-Pacific countries. Clinicopathological information, including sample preparation technique, staining method, original cytologic diagnosis and review diagnosis were collected. RESULTS Of a total of 145 MTC cases retrospectively recruited, 99 (68.3%) were initially interpreted as MTC/suspicious for MTC (S-MTC). The distribution of original FNA diagnostic categories was not associated with the staining method or sample preparation technique. The staining methods used were Papanicolaou, hematoxylin-eosin and Romanowsky stains. Liquid-based cytology (LBC) was used only in three countries. After reviewing all cases, the diagnostic rate of MTC/S-MTC increased to 91.7% (133/145). Cases with initially unrecognized MTC had either marked pleomorphism or cytology mimicking papillary carcinoma or follicular neoplasm. Although LBC provided certain benefits, there was no significant difference in diagnostic accuracy between conventional smear and LBC. Immunocytochemistry was available in 38 cases (26.2%), all of which were correctly recognized as MTC. CONCLUSION Our report summarizes how MTC is handled in contemporary Asian thyroid FNA practice. Although the detection rate of MTC by cytology alone is less satisfactory, integration with ancillary tests could achieve an excellent performance. The recognition of constitutive cytomorphologic features is needed for each cytopreparatory method, which may result in a lower threshold to initiate further workup for MTC.

Abstract
The objective of this study is to report a case of deep endometriosis of the paralumbar muscles (psoas, multifidus, and erector spinae) and review existing literature on its management. A 34-year-old female with a history of endometriosis was seen for infertility. Paralumbar muscle masses seen on computed tomography (CT) scan were sampled, confirming endometriosis. Gonadotropin-releasing hormone agonist was given for 2 months. The patient was primed for assisted reproduction. A literature review was conducted to provide an understanding of paralumbar muscle endometriosis. To our knowledge, this is the first reported case of multifidus and erector spinae muscle endometriosis and fifth case of psoas muscle endometriosis. Because the available information is scarce, data from the existing literature on deep endometriosis may aid in the diagnosis and management. Magnetic resonance imaging and CT scan are essential imaging techniques to map lesions. Excision seems prudent, but the approach should be individualized depending on the patient's presentation and her preferences.

Abstract
The assessment of capsular invasion is an essential but challenging step in the diagnosis of encapsulated follicular thyroid neoplasms. Therefore, interobserver agreement in the assessment of capsular invasion in these tumors was investigated among 11 thyroid pathologists by using virtual slides of 20 cases in which the original diagnosis considered the differential diagnosis of definite capsular invasion versus questionable capsular invasion. The assessment of capsular invasion was divided into three categories: (1) non-invasive, (2) questionable invasive, and (3) clear-cut invasive. The interobserver agreements for clear-cut invasive and non-invasive categories were fair (Kappa value = 0.578 and 0.404, respectively), whereas agreement for the questionable invasion was poor (Kappa value = 0.186). Disagreements in the assessment of invasion resulted in variable final pathological diagnoses. For example, the agreement for a diagnosis of malignancy was only fair (Kappa value = 0.545). Moreover, pathologists did not have a uniform approach for rendering a final diagnosis in cases with questionable capsular invasion, though nine of 11 pathologists did use the follicular tumor of uncertain malignant potential diagnosis as proposed by the World Health Organization classification of endocrine organs published in 2017. In conclusion, this study revealed considerable interobserver variation in the evaluation of capsular invasion, especially in follicular neoplasms with questionable invasion.

Abstract
In the Paris System (TPS), standardized cytomorphological criteria and diagnostic categories were proposed for reporting urine cytology. To evaluate the diagnostic agreement and interobserver concordance for assessing TPS criteria, the Taiwan Society of Clinical Cytology organized an online survey with 10 atypical urine cytology cases. A total of 137 participants completed the survey. The mean agreement of diagnosis was 51.2%, ranging from 34.3% to 83.2% for each case. For 60% (6/10) of cases, the agreement was <50%. The interobserver concordance of diagnosis and cytological criteria assessment showed poor agreement. The nuclear-to-cytoplasmic (N/C) ratio had the highest kappa value of 0.386, indicating a significantly higher interobserver concordance and reproducibility than the other three TPS criteria. The correct rate of assessing the N/C ratio increased as the N/C ratio increased (correlation coefficient: 0.891, p < 0.01). Three cases with an N/C ratio near 0.5 were overestimated. Poor interobserver concordance of diagnosis and TPS criteria was revealed. Compared with other cytological features, the N/C ratio assessment was quantitative and more reproducible, but a tendency to overestimate cells was noted when the N/C ratio was approximately 0.5. Continuing education programs should emphasize the accurate assessment of N/C ratio to improve the application of TPS.

Abstract
AIMS Although Ki67 labelling index (LI) is a prognostic and predictive marker in breast cancer, its accuracy and reproducibility must be validated before its clinical application. We aimed to evaluate the agreement of Ki67 LI in clinical practice in Taiwan. METHODS We conducted a Ki67 immunohistochemistry (IHC) proficiency test. The participants performed the Ki67 IHC test and measured the Ki67 LI of 10 cases of breast cancer tissue on a microarray slide. The staining quality was centrally reviewed based on the Ki67 staining of the tonsil surface epithelium. RESULTS Ki67 staining and counting methods are diverse in Taiwan. The reproducibility of Ki67 LI was poor to good (intraclass correlation coefficient: 0.581, 95% CI 0.354 to 0.802). The reproducibility and agreement in the high staining quality group were significantly higher than those in the low staining quality group. The majority of the Ki67 LIs derived from the low staining quality group were underestimated. Different counting methods did not reveal significant differences when determining Ki67 LI with microarray sections. CONCLUSIONS We suggest using the surface epithelium of the tonsil as external control and achieving optimal staining results that consist of a high positive parabasal layer, a low positive intermediate layer and a negative superficial layer. Good Ki67 staining quality can minimise the staining variations among different laboratories, and it is essential for the reproducibility of Ki67 LI.

Abstract
OBJECTIVES Multi-institutional studies are required for the validation of the Milan System for Reporting Salivary Gland Cytopathology (MSRSGC). METHODS A total of 1,560 fine-needle aspirations of the salivary glands were retrieved from two institutions for a 12-year period. The diagnoses were reclassified based on the MSRSGC. Risk of malignancy (ROM) for each category was calculated based on 694 histologic follow-up cases. RESULTS The ROM for each category was: 18.3% for nondiagnostic, 8.9% for nonneoplastic, 37.5% for atypia of undetermined significance (AUS), 2.9% for benign neoplasm, 40.7% for salivary gland neoplasm of uncertain malignant potential (SUMP), 100% for suspicious for malignancy, and 98.3% for malignant. The sensitivity, specificity, positive predictive rate, and negative predictive rates were 89%, 99%, 98%, and 96%, respectively. CONCLUSIONS The results of the current study are in keeping with the MSRSGC. The indeterminate categories of AUS and SUMP showed intermediate ROMs at 37.5% and 40.7%, respectively.

Abstract
Background The value of this report is the identification of late recurrence with an extremely unusual combination of malignant transformation. In particular, the retroconversion of immature to mature teratoma as well as a somatic-type malignant transformation were both observed postchemotherapeutically in our case. Case presentation We report the case of a 20-year-old girl who completed fertility-sparing surgery and chemotherapy under the diagnosis of ovarian mixed germ cell tumor (immature teratoma and yolk sac tumor) and experienced subsequent recurrence 4 years after a second debulking surgery with a somatic type malignant transformation (teratoma with melanoma and leiomyosarcoma). Multiple metastases developed after a third debulking surgery, and the patient survived for 18 additional months. Conclusions Recurrent disease after repeated cytoreduction and chemotherapy hints a poor outcome despite a generally excellent long-term survival rate among ovarian germ cell malignancies. It is important for clinicians to distinguish those at risk of poorer outcomes and establish individualized postoperative surveillance. Fertility-compromising surgery may be considered in selected patients.

Abstract
Background Alpha-fetoprotein (AFP) is a useful tumor marker for ovarian germ cell tumors, particularly yolk sac tumor (YST). It is valuable for both diagnosis and further follow-up. Epithelial ovarian carcinoma (EOC) rarely secretes AFP, especially for clear cell type and in the postmenopausal women. Based on the limited knowledge about AFP-producing clear cell type EOC, a case and literature review on this topic is extensively reviewed. Case presentation We report a 55-year-old postmenopausal woman experienced vaginal spotting for one month, and serum level of AFP was 60,721 ng/ml initially. Histological examination was clear cell type EOC. Tumor cells revealed strong immunoreactivity for glypican-3 (GPC3) and AFP and weak for hepatocyte nuclear factor-1 beta (HNF-1 beta), but negative for CD30, making the diagnosis of AFP-producing clear cell type EOC with fetal gut differentiation in focal areas, FIGO (International Federation of Gynecology and Obstetrics) IIIc. Although the patient underwent an intensive treatment, including optimal debulking surgery and multi-agent chemotherapy, the patient died of disease. To provide a better understanding of clinical and molecular characteristics of the AFP-producing clear cell type EOC, we conducted a systematic literature review. Conclusions A total of three papers described the AFP-producing clear cell type EOC are available. The overall survival rate of these cases, including the current case is 50%. Although immunohistochemical examination is not always needed in routine for the diagnosis of clear cell type EOC, to distinguish from other tumors, especially germ cell tumors, or to provide the better way to monitor therapeutic response or to evaluate the disease status, immunostaining, including GPC3, HNF-1 beta, CD30, cytokeratin 7 or 20, and AFP is taken into account. Due to rarity, the appropriate chemotherapy regimen and the biological behavior of AFP-producing clear cell type EOC are still unclear.

Abstract
In Taiwan, thyroid cancer is the most common endocrine gland malignancy and the incidence of thyroid cancer has increased four-fold in the past two decades. Fine-needle aspiration is an accurate and cost-effective method of evaluating thyroid nodules and has been the gold-standard diagnostic tool for thyroid tumors in Taiwan since the 1980s. This article reviews the history, current practice, reporting systems, training, and quality assurance for thyroid fine-needle aspiration cytology in Taiwan.

Abstract
The interplay between tumor microenvironment and cancer that causes chemoresistance remains unclear. By analyzing public available microarray datasets, we identified that periostin (POSTN) was overexpressed in cancer stroma in epithelial ovarian cancer (EOC) patients. Immunohistochemistry analysis showed overexpression of stromal POSTN is a powerful independent poor prognostic predictor for EOC patients. Furthermore, patients with high levels of stromal POSTN tend to have higher percentage of cisplatin resistance compared to those with low levels of stromal POSTN. Moreover, we found POSTN treatment can induce cisplatin resistant and activate AKT pathway in A2780 cells in vitro. Inhibition of AKT activity by AKT inhibitor MK-2206 abolished POSTN-induced AKT activation and cisplatin resistance in vitro. Taken together, we found high POSTN expression in cancer microenvironment is correlated with poor prognosis in EOC patients and associated with platinum resistance. The effect of POSTN in cancer stroma cells may activate AKT pathway in tumor and AKT inhibitor can be beneficial to augment the efficacy of existing cancer therapeutics.

Abstract
Here, we present the first cytological report of a primary splenic inflammatory pseudotumor-like follicular dendritic cell sarcoma. The 57 year-old male was incidentally found with a 2.2 cm well-demarcated splenic nodule. A sonography guided fine needle aspiration of the lesion was performed. The cytologic smears revealed loosely cohesive fragments of oval to spindle cells in a background of prominent lymphoplasmacytic infiltration. The cells showed sparse chromatin, distinct nucleoli, syncytial cell borders, and occasional cytoplasmic processes. On the liquid-based preparation, several histiocyte-like cells with emperipolesis phenomenon were noted. Scant large atypical cells with prominent, cherry-red nucleoli were found on the cell block sections. The initial cytologic interpretation was "atypical cells cannot exclude classical Hodgkin lymphoma." The subsequent partial splenectomy showed an inflammatory pseudotumor-like follicular dendritic cell sarcoma. The tumor cells were positive for CD21, CD35, smooth muscle actin, and EBER in situ hybridization. The cytologic differential diagnoses are briefly discussed. The knowledge of this rare entity, awareness of its cytomorphology, and proper ancillary tests would be helpful for correct cytologic diagnosis. Diagn.

Abstract
OBJECTIVE The presence of degenerative endometrial debris and abnormal endometrial cells is considered to be the hint for endometrial pathology. The purpose of this study was to evaluate the efficacy of Papanicolaou (Pap) smears in detecting endometrial cancers. STUDY DESIGN There were 146 cases of endometrial cancer diagnosed at our institute in 2000-2002 and 271 in 2010-2012. Among them, 57 and 95 relevant reports of Pap smears 6 months prior to the histology diagnosis were retrieved for this study, respectively. In the first time period, new criteria for detecting endometrial lesions had not yet been incorporated into routine screening. RESULTS Twenty cases (21%) of adenocarcinoma, 12 (13%) of atypical glandular cells, 4 (4%) of endometrial debris and 59 (62%) negative reports were found among the more recent 95 relevant Pap smears. The overall efficacy of the Pap smear for detecting endometrial malignancy was 38%, higher than 10 years previously (30%). CONCLUSION Although the Pap smear was originally designed to screen cervical lesions, more effective detection of endometrial lesions could be achieved by adding new criteria to the routine screening.

Abstract
OBJECTIVE In a peer comparison educational program, transferring glass slides between laboratories and collecting responses are time- and cost-consuming. Integrating a web-based whole-slide imaging (WSI) system and online questionnaires may serve as a promising solution. STUDY DESIGN Five gynecologic Papanicolaou-stained smears and 5 nongynecologic slides were selected. The 10 whole-slide images were acquired by a Leica SCN-400 system and released via an Aperio eSlide Manager. Online questionnaires generated by Google Forms with access to the 10 whole-slide images were released to all the practitioners in Taiwan by e-mail. After closing the program, an online posttest feedback survey was conducted. RESULTS A total of 302 participants joined the gynecologic test, and 291 joined the nongynecologic test. The correct interpretation rates were 81.8-93.7% in the former and 28.5-93.1% in the latter. In the posttest feedback survey, there were 63.2% of the participants reporting first-time WSI experience, and 97.9% of them said they would like to participate in a similar program again. CONCLUSION Integrating a web-based WSI system and online questionnaires is an easy method to access nationwide practitioners. Participants can make interpretations using WSI even without prior experience. The model is valuable for those who want to initiate a large-scale cytopathology peer comparison educational program.

Abstract
OBJECTIVE We present a case of primary cornual epithelioid trophoblastic tumor (ETT) because of its rarity and diagnostic and therapeutic challenge. CASE REPORT A 28-year-old woman, gravida 1, para 1, who missed menstruation for 3 months, had an elevated β-human chorionic gonadotropin serum level of 2764 mIU/mL, an absence of intrauterine pregnancy, and the presence of an adnexal mass detected by transvaginal ultrasound. As an ectopic pregnancy was suspected, laparoscopic surgery was performed and showed a right corneal mass. Complete excision of the tumor was done through exploratory laparotomy. Frozen pathology favored the diagnosis of squamous cell carcinoma. Since there was no apparent tumor at other sites, no additional surgery was done. The final pathology showed ETT. Primary ETT is often misdiagnosed as an ectopic pregnancy, leading to delayed treatment, and poses a diagnostic challenge in distinguishing it from squamous cell carcinoma during pathological examination. CONCLUSION Careful evaluation and avoidance of overtreatment are emphasized.

Abstract
Gliomatosis peritonei is a very rare phenomenon occurring almost exclusively in association with ovarian immature teratoma. It is characterized by numerous benign, mature glial nodules in the omentum and mesentery. The presence of glial tissue outside abdominal cavity is extremely rare in the setting of ovarian immature teratoma. We present a case of ovarian immature teratoma with both gliomatosis peritonei and pleural glial implant in a 4-year-old girl. Glial emboli were present in the pleural implant, suggesting lymphovascular dissemination might be the cause of extra-abdominal glial implantation.

Abstract
OBJECTIVE To improve the understanding of primary fallopian tube carcinoma (PFTC) through an analysis of possible clinical and pathologic determinants of prognosis. METHODS A retrospective review of the database of a tertiary hospital in Taiwan for 1978-2007 was conducted to identify patients with a diagnosis of PFTC and to evaluate the clinicopathologic features associated with PFTC outcome. RESULTS Fifty-eight patients (mean age 62.5 years) had a diagnosis of PFTC. Stage III/IV disease (55%) and poorly differentiated tumors (52%) were most common. The median follow-up was 93 months (range, 11-333 months). The 5-year disease-free survival rate was 59%, and the overall survival rate was 64%. Factors important in disease-free and overall survival in univariate analysis included the presence of pelvic and/or para-aortic lymph node metastases, International Federation of Gynecology and Obstetrics stage, high preoperative carbohydrate antigen 125 serum level, completion of optimal debulking surgery, and the use of paclitaxel-based chemotherapy; however, only patients with optimal cytoreduction had a decreased hazard of recurrence (hazard ratio [HR] 0.06; 95% confidence interval [CI] 0.01-0.23) and mortality (HR 0.08; 95% CI, 0.02-0.31) in multivariate analysis. CONCLUSION Advanced tumor stage, in particular the presence of lymph node metastases, worsened the prognosis of patients with PFTC. However, optimal debulking surgery significantly improved the prognosis, emphasizing the importance of the treatment strategy.

Abstract
BACKGROUND The microenvironmental biomarkers of different subtypes of ovarian cancers arising from endometriosis have not been studied in Taiwan. Their expression can help in understanding the carcinogenic mechanism. METHODS Our study used immunohistochemistry to compare the expression of estrogen receptor (ER), hepatocyte nuclear factor-1 beta (HNF1ß), p53, phosphatase and tensin homolog (PTEN), BAF250a, and cyclooxygenase-2 (COX-2) among 79 cases of endometriosis-associated ovarian cancers, including 40 (50%) clear cell carcinomas (CCCs), 33 (41%) endometrioid (EM) adenocarcinomas, four (5%) serous carcinomas, one adenosquamous carcinoma, and one adenosarcoma. RESULTS Positive stainings for ER, HNF1ß, p53, and COX-2 were identified in 34 (43%), 30 (38%), 10 (13%), and 44 (56%) cases. Loss of PTEN and BAF250a were noted in 29 (37%) and 37 (47%) cases. The expression of ER was reversely correlated with that of HNF1ß (rho = -0.417, p < 0.001) and correlated with p53 (rho = 0.284, p = 0.011). ER positivity was commonly identified in EM adenocarcinomas (91%), and rarely in CCCs (8%) and serous carcinoma (0%; p < 0.001). By contrast, HNF1ß expression was frequently noted in CCCs (65%) and serous carcinomas (50%), but less in EM adenocarcinoma (6%; p < 0.001). All staining results were similar between atypical endometriosis glandular epithelium and contiguous malignant parts. Only nine cases showed 10 minor differences (10/474, 2%) in ER, HNF1ß, and BAF250a. For the staining patterns of p53, COX-2, and PTEN, there was no difference between the invasive and precursor parts. CONCLUSION Our results supported the suggestion that estrogen-dependent ovarian cancer arising from endometriosis is substantially more associated with EM adenocarcinoma than CCCs. The positive HNF1ß staining was a frequent finding in CCCs, but not in EM adenocarcinoma. The similar staining patterns of atypical endometriosis glandular cells with the invasive parts confirmed their precursor status.

Abstract
A retrospective review was done to evaluate the importance of degenerative endometrial debris accompanied with benign-looking endometrial cells in Papanicolaou (Pap) smears. In total, 306 patients were divided into 2 groups according to the absence (group 1) or presence (group 2) of endometrial debris. Eighty-one (26.5%) patients received histologic follow-up. The biopsy rate for premenopausal patients in group 2 was the highest (24/48 [50%]). Multivariate analysis showed that presence of endometrial debris rather than menopausal status was more related to the biopsy procedure. Malignancy was found more often in group 2 (16/39 [41%]) than in group 1 (2/42 [5%]). A malignant result was also more closely related to endometrial debris rather than menopausal status. Thus, we suggest that benign endometrial cells in Pap smears should be reported and the presence of degenerative endometrial debris is important. Patients with degenerative endometrial debris need comprehensive evaluation, regardless of menopausal status.

Abstract
BACKGROUND & AIMS The impact of overweight and obesity on chronic hepatitis B (CHB) is unclear. This study was to examine the relationship among body mass index, viral load and liver histology in HBeAg-negative CHB. METHODS The study retrospectively investigated 136 HBeAg-negative chronic hepatitis B patients who had undergone liver biopsies in Taiwan. Factors associated with significant liver histology were analyzed. Definitions of overweight and obesity for the Asian population were body mass index≥23 kg/m(2) and ≥25 kg/m(2), respectively. RESULTS The prevalence of overweight, obesity, and type 2 diabetes mellitus in the 136 patients were 22.8%, 52.2%, and 12.5%, respectively. Multivariate analysis identified obesity, AST>40 U/L, HBV DNA>20,000IU/mL and platelet count<150 × 10(9)/L as independent factors associated with significant liver fibrosis. Similarly, overweight/obesity, ALT>80 U/L, HBV DNA>1,000,000IU/mL, and platelet count<150 × 10(9)/L were independent predictors of significant hepatic necro-inflammation. By stratification, high BMI and high viral load patients had more advanced stage and grade of liver histology. CONCLUSIONS Body mass index and HBV viral loads may have synergistic effect on disease progression in HBeAg-negative CHB. Both controlling body weight and anti-viral therapy are important in the management of CHB.

Abstract
Diagnosis of synchronous primary cancers in one patient is a relatively rare event. The well-known synchronous primary cancers of women are combined ovarian and endometrial cancers, especially when both are the endometrioid cell type. Although breast cancer and endometrial cancer are two common female malignancies, they often occur during the postmenopausal period. Therefore, the possibility of concomitant breast cancer and endometrial cancer in a younger woman (premenopausal) is often neglected. The reported case is an example of this situation. A 37-year-old woman was diagnosed with synchronous breast invasive ductal carcinoma and endometrial endometrioid adenocarcinoma. Since this condition is rarely reported, the correlated risk factors are worthy of our attention and the strategy for prevention is highlighted.

Abstract
Adenosarcoma is a rare uterine malignant tumor composed of benign to atypical epithelial element and a usually low-grade sarcomatous component. Although it is well known histologically, its cytological features are rarely described in the literature. We report a case of uterine adenosarcoma being the first one that was accurately diagnosed before operation by the conventional Papanicolaou (Pap) smear with emphasis on the contribution of the integrated immunocytochemical staining. A 46-year-old woman with abnormal vaginal bleeding and a protruding mass from her cervical os. Her Pap smear revealed: (a) presence of endometrial necrotic debris in the background, which indicated the presence of an endometrial lesion, (b) presence of both abnormal endometrial glandular cells (compact and tight clusters with slight hyperchromasia, increased nucleus/cytoplasm (N/C) ratio, apparent nucleoli and moderate vimentin stain) and abnormal stromal cells (loose aggregates of spindle to polygonal cells with hyperchromasia, increased N/C ratio and very strong vimentin staining). The characteristic degenerative necrotic debris indicating endometrial lesion plus the application of immunocytochemistry, which can increase the detection rate of endometrial lesion by the Pap smears. Awareness of the cytological findings of adenosarcoma can aid to make a correct preoperative diagnosis of this rare disease.

Abstract
BACKGROUND It is unclear whether clinical indication for antiviral treatment is in agreement with histological indication in HBeAg-negative chronic hepatitis B (CHB). This study aimed to clarify this relationship and identify factors associated with liver histology. PATIENTS AND METHODS We investigated 152 consecutive, treatment-naïve, HBeAg-negative CHB patients who had undergone liver biopsies at a tertiary medical centre in Taiwan. Clinical indications for treatment included a serum alanine aminotransferase level more than twice the upper limit of normal and an hepatitis B virus DNA level > 2000 IU/ml. Factors associated with the histological indication (Ishak's grade > or = 7 and/or stage > or = 2) were analysed. RESULTS The association between the clinical and the histological indications was significant (P=0.011). However, the agreement was poor (kappa value=0.197). In patients satisfying the clinical indication, age > 52 years [odds ratio (OR)=2.669, P=0.042], serum alpha-fetoprotein (AFP) level > 7 ng/ml (OR=7.070, P<0.001) and platelet count < 130 x 10(9)/L (OR=11.720, P=0.025) were identified to be independent factors associated with histological indication. In patients who did not satisfy the clinical indication, multivariate analysis revealed that only an AFP level > 7 ng/ml (OR=10.345, P=0.021) was independently associated with histological indication. Combining the clinical indication and/or AFP level > 7 ng/ml to predict liver histology, the sensitivity and the negative predictive value could improve from 86 to 94.4% and 66.7 to 81% respectively. CONCLUSION AFP level is associated with liver histology in HBeAg-negative CHB. Serum AFP level can serve as a surrogate indicator to identify patients who need antiviral treatment.

Abstract
Vaccination has been underway in several countries for sexually inactive young girls or women against HPV 16 and 18 to prevent them from infection of these HPV types and concurrent cancer development. However, uterine cervical cancers may remain uncontrolled among some Asian countries, where other types of HPV infection are more frequent. A sensitive cancer screening system would remain important for detection of the earlier stage cervical cancers in Asian countries. In this study, 130 cytotechnologists (CTs) in Asian countries (Taiwan 80, Japan 18, Korea 15, Thailand 11, Singapore 3, Bhutan 2, and Mongolia 1) participated in the vote. Selected 10 cervical Pap smears that would be adequate to identify the diagnostic clues especially for atypical squamous cells (ASC) with two or three representative pictures for each case were displayed on the website. The percentages of consistent diagnosis voted by certified CTs with ≥5 years of experience were compared among 10 cervical cases or among Asian countries enrolled. As results, low consistency for ASC cases and high consistency for squamous intraepithelial lesion (SIL) were observed. Examining specimens for the diagnostic clues of ASC in TBS is crucial to maintain the high sensitivity and positive predictive value of SIL in Asian countries.

Abstract
OBJECTIVE To examine the relationship between human papillomavirus (HPV) and Epstein-Barr virus (EBV) infections in relation to age of patients with cervical adenocarcinoma. MATERIALS AND METHODS Thirty samples of human cervical adenocarcinoma tissue were collected from the surgical pathology archive at Taipei Veterans General Hospital from 1996 to 2008. All samples were examined for EBV, HPV-16 and HPV-18 E6 DNA by conventional and real-time quantitative polymerase chain reaction assays. RESULTS HPV-16 DNA was detected in 10 cases (33.3%), HPV-18 DNA in 12 cases (40%), and EBV DNA in three cases (10%); there were negative findings in seven cases (23.3%). EBV combined with HPV-16 or HPV-18 was also detected in one case each. No link could be demonstrated between HPV and EBV in endocervical lesions. When 20 patients 45 years old were compared with 10 patients > 45 years old, HPV-18 E6 DNA was detected in 45% vs. 30% (9/20 vs. 3/10), HPV-16 E6 DNA in 40% vs. 20% (8/20 vs. 2/10), EBV DNA in 10% vs. 10% (2/20 vs. 1/10), and no virus DNA was detected in 10% vs. 50% (2/20 vs. 5/10). HPV and EBV were significantly more common in younger women (p < 0.001). CONCLUSION HPV-18 plays a major role in adenocarcinomas at any age. A high prevalence of HPV DNA is significantly associated with cervical adenocarcinoma, especially in younger women. The results do not support a role for EBV in cervical adenocarcinogenesis or any relationship between EBV and HPV infection in adenocarcinoma.

Abstract
OBJECTIVE On the basis of outcome data from concurrent chemoradiotherapy (CCRT) for locally advanced cervical squamous cell carcinoma, the authors developed a nomogram for predicting survival outcome. STUDY DESIGN Two hundred fifty-one eligible patients with International Federation of Gynecology and Obstetrics stage IIB-IVA squamous cell carcinoma of the uterine cervix who underwent CCRT were included for the construction of the nomogram. Predictor variables included age, serum squamous cell carcinoma antigen, tumor size, parametrium invasion, hydronephrosis, bladder/rectum invasion, and lymph node metastases. Internal validation of the nomogram was performed. RESULTS A nomogram for predicting the 5 year overall survival for these patients was constructed on the basis of a Cox regression model from 7 parameters. The concordance index was 0.69. CONCLUSION This nomogram is a predictive tool, upon external validation, that can be used to counsel patients in predicting outcomes. The discriminatory ability of the nomogram indicates that this population should not be considered homogeneous with respect to risk of death.

Abstract
Increased intrahepatic resistance (IHR) within cirrhotic liver is caused by increased endotoxemia, cytokines tumor necrosis factor-alpha (TNF-alpha), vasoconstrictor thromboxane A(2) (TXA(2)), and disrupted microvasculatures. We evaluated the effects of thalidomide-related inhibition of TNF-alpha upon the hepatic microcirculation of cirrhosis in rats. Portal venous pressure (PVP), hepatic TNF-alpha, expression of thromboxane synthase (TXS), and leukocyte common antigen (LCA) were measured in bile-duct-ligated (BDL) rats receiving 1 month of thalidomide (BDL-thalido rats). Portal perfusion pressure (PPP), IHR, and hepatic TXA(2) production were measured in the isolated liver perfusion system. Intravital microscopy was used to examine hepatic microvascular disruptions. In BDL-thalido rats, PVP, PPP, IHR, hepatic TXA(2) and TNF-alpha, hydroxyproline content, expression of TXS and LCA, and LPS-induced leukocyte recruitment were significantly decreased. Conversely, hepatic microvascular density and perfused sinusoids were significantly increased. Thalidomide decreased PVP and IHR by reducing hepatic TXA(2) and improving hepatic microvascular disruptions in rats with biliary cirrhosis.

Abstract
OBJECTIVE Aurora kinases such as Aurora A and B are key regulators of mitosis and tumorigenesis and have been reported to be overexpressed in various malignancies. However, the expression of Aurora kinases in normal and neoplastic cervical tissues remains undetermined. STUDY DESIGN Immunohistochemical expression of Aurora A and B kinase was examined in 20 normal cervix, 35 cervical intraepithelial neoplasm 3 (CIN 3) and 95 cervical cancers, including squamous cell carcinoma (SCC) (n=76) and adenocarcinoma (AC) (n=19). Expression of Aurora A and B kinase was confirmed by Western blot. The correlation between Aurora A and B kinases expression and the clinico-pathological parameters was analyzed by statistical analysis. RESULTS The Aurora A and B expression was significantly increased in carcinoma and CIN 3, compared with normal cervix. However, expression of Aurora A and B showed no significant correlation between CIN 3 and cervical cancer. The nuclear expression of Aurora A showed a significantly positive correlation with the expression of Aurora B (P=0.018). The percentage of Aurora A overexpression between SCCs and ACs showed a significant difference (50% vs. 21.1%, P=0.023). However, there was no correlation of Aurora A and B expression with patient survival. CONCLUSION According to our study, Aurora A and B overexpression is a relatively early phenomenon in the genesis of malignant epithelial neoplasm tumorigenesis. Based on the results of this study, it would be interesting to know whether Aurora kinases play a role in pathogenesis of cervical dysplasia and SCC patients.
