Abstract
INTRODUCTION Patients with POLE (polymerase epsilon) mutation (POLEmut)-subtype, MMR-deficient (MMR-d)-subtype as classified by the Cancer Genome Atlas (TCGA), and a high tumor mutation burden (TMB-high) potentially benefit from immunotherapy. However, characteristics of the cytological morphology within these populations remain unknown. METHODS DNA extracted from formalin fixed paraffin embedded tissues was subjected to next-generation sequencing analysis. Genomic mutations related to gynecological cancers, TMB, and microsatellite instability (MSI) were analyzed and were placed in four TCGA classification types. The following morphological cytological investigations were conducted on endometrial cancer using a liquid-based preparation method, prior to the commencement of initial treatment: i) cytological backgrounds; ii) differences between each count of neutrophils and lymphocytes as described below. RESULTS Insignificant differences in the cytological background patterns of TCGA groups and TMB status were found. Although there was no significant difference in neutrophil count (p= 0.955) in the TCGA groups, POLEmut and MMR-d had significantly higher lymphocyte counts than no specific molecular profile (NSMP) (p= 0.019 and 0.037, respectively); furthermore, p53mut also tended to be significant (p= 0.064). Lymphocyte counts in TMB-high were also significantly greater than TMB-low (p= 0.002). POLEmut showed a positive correlation between TMB levels and lymphocyte counts. For predicting patients with POLEmut plus MMR-d, lymphocyte counts demonstrated a superior diagnostic accuracy of Area Under the Curve(AUC)(0.70, 95% CI: 0.57-0.84), with a cut-off value of 26 high-power field(HPF). CONCLUSION Lymphocyte count using liquid-based cytology for patients with endometrial cancer may predict POLEmut plus MMR-d of TCGA groups and TMB-high in those who can benefit from immunotherapy.

Abstract
Background Although rare, cases of hypophysitis resembling a pituitary abscess (PA) have been reported. Differential diagnosis between hypophysitis and PA is crucial as the two diseases require different treatments. Case Description A 38-year-old woman with headaches underwent head magnetic resonance imaging (MRI), which revealed an 11-mm mass lesion in the sella turcica. Due to breastfeeding, contrast-enhanced MRI was avoided. Pituitary adenomas and Rathke's cleft cyst (RCC) were suspected, and she was initially treated conservatively. Five months later, she acquired syndrome coronavirus two infections, and while the fever subsided with acetaminophen, the headache persisted. One month later, the headache worsened, followed by fever and diabetes insipidus. MRI revealed a pituitary cystic mass with ring-shaped contrast enhancement on T1-weighted MRI and increased signal intensity on diffusion-weighted imaging (DWI). PA was suspected, and emergency endoscopic transsphenoidal surgery was performed. The microbiological examination of the yellowish-brown content drained from the cystic mass was negative. Microscopically, the cystic lesion was covered with ciliated columnar epithelium and stratified squamous epithelium, with a dense inflammatory cell infiltrate consisting mainly of lymphocytes and plasma cells observed around the cyst. This supported the diagnosis of secondary hypophysitis associated with RCC without PA. Conclusion We report a case of hypophysitis secondary to RCC resembling PA with ring-shaped contrast enhancement on MRI and increased signal intensity on DWI. This case emphasizes the need for cautious diagnosis of secondary hypophysitis due to RCC in individuals with MRIs and clinical manifestations resembling an abscess.

Abstract
BACKGROUND/AIM Among the four genomic subtypes of endometrial cancer, distinguishing between the DNA polymerase epsilon mutation (POLEmut) and no specific molecular profile (NSMP) subtypes requires genomic profiling owing to the lack of surrogate immunohistochemical markers. We have previously found that, histologically, the POLEmut-subtype exhibits surface epithelial slackening (SES). Therefore, to improve subtype identification, we aimed to extract cytological features corresponding to SES in POLEmut-subtype cervical cytology specimens. MATERIALS AND METHODS We analyzed 104 endometrial cancer cervical cytology specimens, with integrative diagnosis confirmation via histology, immunohistochemistry, and genomic profiling. Cytological features were evaluated for the presence of atypical glandular cells, atypical cell appearance in single cells and clusters, and cytological SES and the presence of tumor-infiltrating inflammatory cells in clusters. RESULTS Based on cervical cytology, the POLEmut- and p53mut-subtypes exhibited more frequent atypical cells in smaller clusters, giant tumor cells, and cytological SES patterns than the NSMP-subtype. Tumor-infiltrating lymphocytes were frequent in the POLEmut- and mismatch repair-deficient subtypes. CONCLUSION Histologically-detected SES as well as other endometrial cancer features may be preserved in the atypical cell clusters observed in cervical cytology specimens. Cytological detection of SES and of smaller clusters of atypical cells and inflammatory cells with moderate atypia are suggestive of POLEmut-subtype. Integrative diagnosis including genomic profiling remains critical for diagnostic confirmation.

Abstract
The diagnosis of synchronous endometrial and ovarian cancer or metastatic cancer of the same histological type is difficult. In this study, molecular biology analysis was performed to determine ovarian metastasis from endometrial cancer. A 38-year-old woman had pathological evidence of endometrial cancer (endometrioid carcinoma, grade 1) and ovarian cancer (endometrioid carcinoma, grade 3); a disseminated nodule in the serosa uteri was also diagnosed as endometrioid carcinoma (grade 3). Customized panel sequencing revealed a common mutation pattern in ovarian cancer and disseminated nodules. Furthermore, endometrial cancer showed the same mutation patterns for FGFR3 and PTEN as ovarian cancer and disseminated nodules. All tumors were microsatellite instability high. Clinicopathological and molecular biology analyses suggested that the patient had ovarian metastasis from endometrial cancer. The patient underwent adjuvant chemotherapy with paclitaxel and carboplatin, with no recurrence. Molecular biology techniques may enable appropriate treatment based on clinically accurate diagnosis.

Abstract
BACKGROUND Low-grade fibromyxoid sarcoma (LGFMS) is a rare type of sarcoma which is observed in the soft tissue of proximal extremities, typically in young and middle-aged adults. It consists of a solid proliferation of bland spindle cells within collagenous and myxoid stroma. CASE REPORT Herein, we report a case of LGFMS with massive degeneration and hyalinization. A 30-year-old man presented with a well-circumscribed mass measuring 15 cm in diameter in his left biceps femoris muscle. Marginal tumor resection was performed under the clinical diagnosis of an ancient schwannoma or chronic expanding hematoma (CEH). The resected tissue revealed a well-demarcated tumor mass with massive degeneration and hyalinization with focal calcification. Proliferation of spindle tumor cells with abundant collagenous stroma, which resembled the fibrous capsule of CEH, was observed exclusively in a small area of the periphery of the tumor. No nuclear palisading, myxoid stroma, or collagen rosettes were identified. Immunohistochemical analysis demonstrated that the spindle tumor cells expressed mucin 4 and epithelial membrane antigen. Reverse transcriptase-polymerase chain reaction analysis detected mRNA expression of fused in sarcoma::CAMP-responsive element binding protein 3-like protein 2 (FUS::CREB3L2) fusion gene. Thus, a final diagnosis of LGFMS with massive degeneration and FUS::CREB3L2 fusion was made. CONCLUSION The recognition of massive degeneration and hyalinization as unusual features of LGFMS might be helpful to differentiate it from CEH and other benign spindle-cell tumors.

Abstract
BACKGROUND Oscillating gradient diffusion-weighted imaging (DWI) enables elucidation of microstructural characteristics in cancers; however, there are limited data to evaluate its utility in patients with endometrial cancer. PURPOSE To investigate the utility of oscillating gradient DWI for risk stratification in patients with uterine endometrial cancer compared with conventional pulsed gradient DWI. STUDY TYPE Retrospective. SUBJECTS Sixty-three women (mean age: 58 [range: 32-85] years) with endometrial cancer. FIELD STRENGTH/SEQUENCE 3 T MRI including DWI using oscillating gradient spin-echo (OGSE) and pulsed gradient spin-echo (PGSE) research sequences. ASSESSMENT Mean value of the apparent diffusion coefficient (ADC) values for OGSE (ADCOGSE ) and PGSE (ADCPGSE ) as well as the ADC ratio (ADCOGSE /ADCPGSE ) within endometrial cancer were measured using regions of interest. Prognostic factors (histological grade, deep myometrial invasion, lymphovascular invasion, International Federation of Gynecology and Obstetrics [FIGO] stage, and prognostic risk classification) were tabulated. STATISTICAL TESTS Interobserver agreement was analyzed by calculating the intraclass correlation coefficient. The associations of ADCOGSE , ADCPGSE , and ADCOGSE /ADCPGSE with prognostic factors were examined using the Kendall rank correlation coefficient, Mann-Whitney U test, and receiver operating characteristic (ROC) curve. A P value of <0.05 was statistically significant. RESULTS Compared with ADCOGSE and ADCPGSE , ADCOGSE /ADCPGSE was significantly and strongly correlated with histological grade (observer 1, τ = 0.563; observer 2, τ = 0.456), FIGO stage (observer 1, τ = 0.354; observer 2, τ = 0.324), and prognostic risk classification (observer 1, τ = 0.456; observer 2, τ = 0.385). The area under the ROC curves of ADCOGSE /ADCPGSE for histological grade (observer 1, 0.92, 95% confidence intervals [CIs]: 0.83-0.98; observer 2, 0.84, 95% CI: 0.73-0.92) and prognostic risk (observer 1, 0.80, 95% CI: 0.68-0.89; observer 2, 0.76, 95% CI: 0.63-0.86) were significantly higher than that of ADCOGSE and ADCPGSE . DATA CONCLUSION The ADC ratio obtained via oscillating gradient and pulsed gradient DWIs might be useful imaging biomarkers for risk stratification in patients with endometrial cancer. LEVEL OF EVIDENCE 3 TECHNICAL EFFICACY: Stage 2.

Abstract
PURPOSE To develop and identify machine learning (ML) models using pretreatment clinical and 2-deoxy-2-[18F]fluoro-D-glucose positron emission tomography ([18F]-FDG-PET)-based radiomic characteristics to predict disease recurrences in patients with breast cancers who underwent surgery. PROCEDURES This retrospective study included 112 patients with 118 breast cancer lesions who underwent [18F]-FDG-PET/ X-ray computed tomography (CT) preoperatively, and these lesions were assigned to training (n=95) and testing (n=23) cohorts. A total of 12 clinical and 40 [18F]-FDG-PET-based radiomic characteristics were used to predict recurrences using 7 different ML algorithms, namely, decision tree, random forest (RF), neural network, k-nearest neighbors, naive Bayes, logistic regression, and support vector machine (SVM) with a 10-fold cross-validation and synthetic minority over-sampling technique. Three different ML models were created using clinical characteristics (clinical ML models), radiomic characteristics (radiomic ML models), and both clinical and radiomic characteristics (combined ML models). Each ML model was constructed using the top ten characteristics ranked by the decrease in Gini impurity. The areas under ROC curves (AUCs) and accuracies were used to compare predictive performances. RESULTS In training cohorts, all 7 ML algorithms except for logistic regression algorithm in the radiomics ML model (AUC = 0.760) achieved AUC values of >0.80 for predicting recurrences with clinical (range, 0.892-0.999), radiomic (range, 0.809-0.984), and combined (range, 0.897-0.999) ML models. In testing cohorts, the RF algorithm of combined ML model achieved the highest AUC and accuracy (95.7% (22/23)) with similar classification performance between training and testing cohorts (AUC: training cohort, 0.999; testing cohort, 0.992). The important characteristics for modeling process of this RF algorithm were radiomic GLZLM_ZLNU and AJCC stage. CONCLUSIONS ML analyses using both clinical and [18F]-FDG-PET-based radiomic characteristics may be useful for predicting recurrence in patients with breast cancers who underwent surgery.

Abstract
Endometrial cancers are classified into mismatch repair (MMR) deficient- (MMRd), p53 mutation- (p53mut), DNA polymerase epsilon (POLE) mutation (POLEmut), and no specific molecular profile (NSMP) subtypes according to The Cancer Genome Atlas (TCGA). The distinction between POLEmut and NSMP subtypes is made on the basis of molecular analysis because the specific histological and immunohistochemical features of these two subtypes are still unknown. In this study, we analyzed histological features by scoring the presence of a mucinous pool, giant cells, clear cells, keratinization, neutrophilic abscess, and surface proliferating pattern in 82 cases of endometrial cancers in which an integrative diagnosis was confirmed by immunohistochemistry and genomic profiles showing POLE mutations, tumor mutation burden, and microsatellite instability. In contrast to the hierarchical branching of micropapillary proliferation observed in serous carcinoma, POLEmut-subtype endometrioid carcinomas often showed a surface epithelial slackening (SES) pattern in the tumor cells facing the uterine surface. The POLEmut subtype exhibited higher scores for clear cells and SES patterns than the other three subtypes. The scores for giant cells, clear cells, and the SES pattern were significantly higher in the POLEmut subtype than in the NSMP subtype, suggesting that these morphometric parameters are useful for differentiating POLEmut- and NSMP-subtype endometrioid carcinomas, although genomic profiling is still necessary for a definite molecular diagnosis.

Abstract
OBJECTIVE For patients with endometrial cancer, the POLE (polymerase epsilon) mutation (POLEmut)-subtype, one of four molecular-analysis-based categories in the Cancer Genome Atlas (TCGA), has the best prognosis. The following histological characteristics are typically observed in endometroid carcinoma cases with the POLEmut-subtype: (1) the presence of tumour giant cells, (2) numerous tumour-infiltrating lymphocytes (TILs) and/or peri-tumoral lymphocytes, and (3) a high grade. However, in the context of cytology, the morphological characteristics of this subtype remain unknown. METHODS DNA extracted from formalin-fixed paraffin-embedded (FFPE) tissues was subjected to next-generation sequencing analysis and categorised according to the TCGA classifications. Genomic mutation, tumour mutation burden (TMB), and microsatellite instability were also assessed. Cytological specimens of resected uteri obtained using the Papanicolaou method were histologically separated into three types. RESULTS Seven out of 112 patients (6%) with endometrial cancer were diagnosed with the POLEmut-subtype between January 2019 and August 2021. Tumour giant cells were observed in three cases (43%) on histology and cytology. TIL and/or peritumoral lymphocytes with inflammatory cells were detected in five cases (71%) on histology and three cases (43%) on cytology. Cases in which these three characteristics were observed on both cytology and histology may have belonged to the POLEmut-subtype. There were no cases in which these characteristics were absent on histology but present on cytology. TMB tended to be higher in cases when the three characteristics were observed in both cytological and histological findings. CONCLUSIONS Preoperative endometrial cytology highlighted the characteristics of the POLEmut-subtype in the histological analysis of resected uterine specimens and has the potential to play an important role in treatment decisions.

Abstract
RATIONALE I-131 radioiodine false-positive findings in postoperative patients with differentiated thyroid cancer (DTC) should be recognized to avoid unnecessary therapies. PATIENT CONCERNS AND DIAGNOSES A 50-year-old man underwent I-131 therapy 3 times, including the initial ablative therapy after total thyroidectomy for papillary thyroid cancer. The initial I-131 posttherapeutic whole-body scintigraphy showed 2 cervical and one superior mediastinal focal I-131 positive uptake lesions. The serum thyroglobulin level was negative every time when the radioiodine therapy was performed. Although the 2 cervical positive uptake lesions disappeared after the second therapy, the superior mediastinal I-131 positive uptake persisted even after the third therapy, and this lesion was suspicion of I-131 therapy-resistant node metastasis. INTERVENTIONS AND OUTCOMES The lesion was resected, and the pathological diagnosis with immune-histochemical analysis was a thymic cyst with thymic epithelial cells having a weak expression of the sodium-iodide symporter (NIS). LESSONS The false-positive result may be attributed to the NIS expression in the thymic cyst epithelial cells. It is necessary to include a thymic cyst in the differential diagnosis, when I-131 uptake is noted in the superior mediastinal region on I-131 posttherapeutic scans of patients with postoperative DTC. Although the I-131 positive uptake in a thymic cyst may be influenced by the I-131 administered dose and scan timing after I-131 administration, the NIS expression may be essential to the false-positive uptake in a thymic cyst.

Abstract
POLE mutation-type endometrial cancer is characterized by an extremely high tumor mutation burden. Most POLE mutation-type endometrial cancers are histologically endometrioid carcinomas, and POLE mutation-type carcinosarcomas are rare among endometrial cancers. We report a case of endometrial and pelvic cancer in a 53-year-old woman who was analyzed using next-generating sequencing. The endometrial lesion harbored a p.T457del POLE mutation with an elevated tumor mutation burden and low microsatellite instability. The pelvic lesion showed divergent histological features, consisting of high-grade endometrioid carcinoma, neuroendocrine carcinoma, and chondrosarcoma. In addition to the common POLE mutation detected in the endometrial lesion, the pelvic lesion in each element showed additional gene mutations in a hierarchical manner. Therefore, it is indicated that the p.T457del POLE mutation is a pathogenic mutation and may be related to POLE mutation-induced carcinogenesis and divergent morphogenesis in endometrial cancer.

Abstract
Vulvar proximal-type epithelioid sarcoma during pregnancy is extremely rare. Immediate and agressive treatment is essential even in pregnancy, and vulvectomy during pregnancy is considered safe. Further reserch is required to discuss about the effectiveness of adjuvant therapy.
Vulvar proximal-type epithelioid sarcoma during pregnancy is extremely rare; only two reports are available to date. Herein, we describe a 36-year-old woman who presented with a pigeon-egg-sized solid mass with cystic component on the left labia majora at 18 weeks of gestation. The patient underwent tumor resection at 23 weeks of gestation and was diagnosed with epithelioid sarcoma, proximal-type. At 29 weeks of gestation, elective cesarean section, radical local resection of the vulva and vagina, and inguinal lymphadenectomy were performed. After surgery, she underwent six courses of adjuvant chemotherapy (doxorubicin 60 mg/m2 and cisplatin 50 mg/m2) every four weeks. The patient and her baby survived with neither recurrence nor complications until 5 years. Aggressive management for proximal-type epithelioid sarcoma, such as early termination of pregnancy and operation, can improve maternal outcomes.

Abstract
Solitary fibrous tumor (SFT) or hemangiopericytoma (HPC) is a rare fibroblastic tumor of mesenchymal origin. SFT or HPC comprises <1% of all primary central nervous system tumors. SFT or HPC of the sellar or suprasellar region is even more unusual. We herein report a sellar SFT or HPC in an octogenarian who achieved favorable progress with partial removal followed by fractionated gamma knife radiosurgery. An 87-year-old woman presented with occasional headache and visual field defects. A rapidly growing tumor of the sella turcica was diagnosed. The patient underwent endoscopic transnasal transsphenoidal surgery; however, only partial resection of the tumor was possible, as it was fibrous and hard with increased vascularity. A histological examination confirmed the tumor to be grade II SFT or HPC. Two months after the resection, the residual tumor grew rapidly. Given the patient’s advanced age, re-surgery was not the preferred option; thus, fractionated gamma knife radiosurgery (marginal dose, 30 Gy in five fractions) was performed. MRI and visual field examination performed 3 months after irradiation revealed tumor shrinkage and improvement in the visual field, respectively. One year and three months after irradiation, the tumor continued to shrink and her visual field had improved. Taking age into consideration, partial resection with fractionated gamma knife radiosurgery was the more appropriate choice for both local tumor control and the safety of the optic apparatus.

Abstract
It is often difficult to histologically differentiate among endometrial dedifferentiated carcinoma (DC), endometrioid carcinoma (EC), serous carcinoma (SC), and carcinosarcoma (CS) due to the presence of solid components. In this study, we aimed to categorize these carcinomas according to The Cancer Genome Atlas (TCGA) classification using a small custom-made cancer genome panel (56 genes and 17 microsatellite regions) for integrated molecular diagnosis. A total of 36 endometrial cancer cases with solid components were assessed using IHC, next-generation sequencing (NGS), and the custom-made panel. Among 19 EC cases, six were categorized as MMR-deficient (MMR-d) and eight were classified as having a nonspecific molecular profile. Three EC cases were classified as POLE mutation (POLEmut)-type, which had a very high tumor mutation burden (TMB) and low microsatellite instability (MSI). Increased TMB and MSI were observed in all three DC cases, classified as MMR-d with mutations in MLH1 and POLD1. Except for one case classified as MMR-d, all SC cases exhibited TP53 mutations and were classified as p53 mutation-type. SC cases also exhibited amplification of CCND1, CCNE1, and MYC. CS cases were classified as three TCGA types other than the POLEmut-type. The IHC results for p53 and ARID1A were almost consistent with their mutation status. NGS analysis using a small panel enables categorization of endometrial cancers with solid proliferation according to TCGA classification. As TCGA molecular classification does not consider histological findings, an integrated analytical procedure including IHC and NGS may be a practical diagnostic tool for endometrial cancers.

Abstract
Objective To evaluate the accuracy of the one-step nucleic acid amplification (OSNA) assay for the diagnosis of lymph node (LN) metastasis in uterine cancer. Methods A total of 116 LNs from 30 patients with cervical and endometrial cancer, enrolled in this prospective study, were used. Excised LNs were cut into 4 to 6 blocks at 2 mm intervals, and nonadjacent blocks were alternately subjected to either histological examination or the OSNA assay. Results The concordance rate between histological examination and the OSNA assay in cervical cancer and in endometrial cancer was 95.9% and 95.2%, respectively. The sensitivity, specificity, and negative predictive value of the OSNA assay were 80%, 97.7%, and 97.7% in cervical cancer, and 85.7%, 93.3%, and 98.2% in endometrial cancer, respectively. In cervical cancer, discordant results were observed in 2 out of 49 LNs (4.1%); 1 was OSNA assay-positive and histological examination-negative, and 1 was OSNA assay-negative and histological examination-positive. In endometrial cancer, discordant results were observed in 5 out of 67 LNs (7.5%); 4 were OSNA assay-positive and histological examination-negative, and 1 was OSNA assay-negative and histological examination-positive. Conclusion The OSNA assay showed high concordance rate with histological examination, sensitivity, and specificity in uterine cancer, suggesting that it could enhance the accuracy of conventional pathological examination for the detection of LN metastasis by reducing false negative rate. High concordance rate between the one-step nucleic acid amplification (OSNA) assay and histological examination in uterine cancer. OSNA assay demonstrates high sensitivity and specificity for metastatic lymph node detection. Preoperative confirmation of cytokeratin 19 expression in primary tumors may reduce false-negative results.

Abstract
Extramedullary hematopoiesis (EMH) in adults usually occurs in the liver, spleen, and lymph nodes when bone marrow hematopoiesis fails. EMH has also been recognized in benign or malignant hepatic tumors, such as hepatoblastoma, hepatocellular adenoma, and vascular tumors. However, it is rarely encountered in hepatocellular carcinoma (HCC) in elderly adults, and the molecular mechanism of EMH in hepatic tumors remains unclear. We present a case of a 74-year-old man without any hematopoietic disorders and hepatitis viral infection who underwent hepatic resection for HCC. Histological examination revealed a well-differentiated HCC with trilineage hematopoiesis in the tumor and non-neoplastic liver. The coexistence of HCC and EMH in adult patients with no hematopoietic disorders is very rare and must be distinguished from poorly differentiated or dedifferentiated HCC and hepatoblastoma.

Abstract
Primary vaginal carcinosarcoma (VCS) is an extremely rare and aggressive tumor consisting of admixed malignant epithelial and mesenchymal elements. We report a case of VCS that was subjected to analysis by immunohistochemistry and next-generation sequencing (NGS). A 53-year-old woman with post-menopausal vaginal bleeding underwent surgical excision followed by concurrent chemoradiation. A well demarcated tumor was growing in a discontinuous fashion at a location some distance from both the cervix and vulva. Microscopically, the tumor consisted of adenocarcinoma components and sarcoma components consisting of a sheet-like growth of spindle-shaped cells, and we diagnosed this tumor as primary vaginal carcinosarcoma. NGS analysis of each component identified the following variants, TP53, PIK3CA, KRAS and FBXW7. A comparison of microsatellite instability (MSI) and tumor mutation burden (TMB) showed that within both tissues the sarcomatous components had a higher MSI and TMB than the carcinomatous components. This case supports "a monoclonal theory" with the genome profile being similar to other malignant mixed Müllerian tumors.

Abstract
BACKGROUND Genomic examination of cytology specimens is often performed on cell blocks or conventional smears rather than on liquid-based cytology (LBC) specimens. Since LBC specimens preserve high-quality DNA, cancer genome profiling using next-generation sequencing (NGS) is also attainable from residual LBC specimens. One of the advantages of using LBC specimens for NGS is that it allows direct extraction of DNA from residual specimens, avoiding a sacrifice of smear slides and minimizing genomic profiling processing time. METHODS Endometrial LBC specimens were subjected to NGS analysis to validate the practicality of rapid cancer genomic profiling in a pathology laboratory. The extracted DNA was subjected to NGS using a customized cancer gene panel comprising 56 genes and 17 microsatellite regions. The workflow strategy was defined, and the processing time estimated for specimen sampling, cell counting, NGS run, and genome profiling. RESULTS NGS analysis of most LBC specimens revealed somatic mutations, tumor mutation burden, and microsatellite instability, which were almost identical to those obtained from formalin-fixed paraffin-embedded tissues. The processing time for direct NGS analysis and cancer genomic profiling of the residual LBC specimens was approximately 5 days. CONCLUSION The residual LBC specimens collected using endometrial cytology were verified to carry a high tumor fraction for NGS analysis and could serve as an alternate source for rapid molecular classification and diagnosis of endometrial cancers, as a routine process in a pathology laboratory.

Abstract
Sarcoidosis is a systemic granulomatous disease. In pulmonary sarcoidosis, granulomatous vascular involvement is a common feature that occurs in all types of vessels, including large elastic arteries to venules, but sarcoidosis complicated with pulmonary infarction has not been reported. We report a case of a 60 years old female, who was operated on a clinical diagnosis of lung cancer, and histological examination revealed a pulmonary infarction and sarcoidosis. In the pulmonary elastic arteries, granulomas infiltrated the adventitia and media, and caused elastic fiber collapse and destruction. Arterial occlusion by granulomas was observed in the edge of the infarcted area. It was considered that the arterial sarcoidosis granuloma involvement was the cause of pulmonary infarction. Sarcoidosis is a significant risk factor for cardiovascular events. However, pulmonary infarction is an extremely rare complication of sarcoidosis. Our case suggests that sarcoidosis may cause vascular events in the lungs.

Abstract
BACKGROUND Carcinoma of the ampulla of Vater is an uncommon ampullo-pancreatobiliary neoplasm, and the most common histological type is adenocarcinoma with a tubular growth pattern. Invasive micropapillary carcinoma (IMPC) is an aggressive variant of adenocarcinoma in several organs that is associated with lymph node metastasis and poor prognosis. IMPC was first described as a histological subtype of breast cancer; however, IMPC of the ampulla of Vater is extremely rare, with only three articles reported in the English literature.
CASE SUMMARY We have reported a case of IMPC of the ampulla of Vater in an 80-year-old man. Microscopically, the surface area of the carcinoma was composed of tubulopapillary structures mimicking intra-ampullary papillary-tubular neoplasm, and the deep invasive front area exhibited a pattern of IMPC. The carcinoma showed lymphatic invasion and extensive lymph node metastasis. The immunohistochemical study revealed mixed intestinal and gastric/pan-creatobiliary phenotypes.
CONCLUSION This rare subtype tumor in the ampulla of Vater showed a histologically mixed phenotype and exhibited aggressive behavior.

Abstract
Primary vaginal neuroendocrine carcinoma (NEC) is extremely rare among female genital tract tumors. Here, we report 2 cases of vaginal small cell NEC (SCNEC) using immunohistochemistry and next-generation sequencing (NGS) analysis. The 2 patients were in their mid-to-late 70s, presented with abnormal vaginal bleeding and had a vaginal submucosal mass. The biopsied or resected tumors showed a typical neuroendocrine morphology consisting of solid nests of atypical tumor cells, with no specific organoid patterns, and proliferating in the vaginal submucosa. Immunohistochemical analysis showed strong and diffuse expression of chromogranin A, synaptophysin, and p16, but no thyroid transcription factor 1 expression. Additionally, both cases were positive for human papillomavirus (HPV) 18. An NGS-based cancer panel analysis revealed that the tumors carried NF1 and AR mutations, but no major driver mutations were detected. The results of this study suggested that HPV18 infection is linked to vaginal SCNEC.

Abstract
Purkinje cell protein 4/peptide 19 (PCP4/PEP19) is 7.6 kDa peptide originally found in Purkinje cells. PCP4/PEP19 is a differentiation maker of Purkinje cells, where it functions as an antiapoptotic factor. Cerebral neuronal cells also express PCP4/PEP19, which may be related to neuronal cell survival. However, evidence suggests that PCP4/PEP19 may also be involved in neuronal differentiation. Here, we investigated the effects of PCP4/PEP19 expression on neuronal differentiation by analyzing neurite outgrowth, and expression of neuronal differentiation markers in cultured human neuroblastoma M17 cells. When PCP4/PEP19 expression was reduced by siRNA-mediated knockdown, neurite outgrowth was significantly increased. Among many differentiation markers tested, expression of NeuroD1 was increased, while that of Ascl1 was decreased upon PCP4/PEP19 knockdown. Furthermore, luciferase reporter assays revealed that PCP4/PEP19 knockdown upregulated NeuroD1 and downregulated Ascl1 expression, at the transcriptional level. These results suggest a new function of PCP4/PEP19, which suppresses neurite outgrowth and neuronal differentiation through the regulation of NeuroD1 and Ascl1 expression in M17 cells. Furthermore, immunohistochemical studies showed that PCP4/PEP19 localizes in the nuclei of human neuroblastoma cells. Therefore, PCP4/PEP19 may also be an intranuclear negative regulator of neuronal differentiation and may thus be a potential therapeutic target to promote cellular differentiation in human neuroblastoma.

Abstract
Verruciform xanthoma is a rare benign verrucopapillary lesion that develops in the oral mucosa and genital skin. Its development in the esophagus is extremely rare, with only 5 reported cases. We present 2 cases of verruciform xanthoma of the esophagus. Case 1 involved a 91-year-old woman, who had hypertension and chronic gastritis with Helicobacter pylori infection, with a 12-year history of a 10-mm white-yellow elevated lesion on the esophagus, 35 cm from the incisor teeth. Case 2 involved a 70-year-old man with fundic gland polyp, hyperlipidemia, and lung cancer, who had a 10-mm whitish granular/verrucoid lesion on the esophagus, 28 cm from the incisor teeth. Microscopically, these lesions show verrucous and papillomatous epithelial hyperplasia with neutrophilic intraepithelial exocytosis. The histological hallmark is the presence of numerous foamy histiocytes infiltrating the elongated squamous epithelial papillae. Although its etiology is unknown, irritation or trauma caused by radiotherapy has been suggested.

Abstract
Background Epignathus is a rare congenital orofacial teratoma infrequently associated with intracranial extension. Intracranial extension of an epignathus indicates a poor prognosis; however, only a small number of such cases have been reported. While there have been some studies reporting cases of epignathus expanding directly into the cranium, others have reported no communication between an epignathus and an intracranial tumor. Case presentation A fetus at gestational week 27 was suspected of having an epignathus with intracranial tumor as shown by ultrasonographic and magnetic resonance imaging. The fetus was stillborn and an autopsy was performed. An epignathus measuring 12 × 6 × 6 cm and weighing 270 g protruded from the mouth, with its base on the soft palate. An intracranial tumor weighing 14 g was located at the middle intracranial fossa and connected to the epignathus through the right side of the sella turcica. The intracranial tumor was encapsulated, and there was no invasion into the brain. Histologically, both the epignathus and intracranial tumor were immature teratomas, with neural and pulmonary components that were especially immature as compared to those of the internal organs and brain tissues of the fetus. Conclusion There have been several reports of epignathus and intracranial tumors that did not communicate; therefore, careful evaluation is needed when a fetus is suspected of having an epignathus extending into an intracranial lesion. Our case supports the findings that an epignathus can directly expand into the cranium. Moreover, this is a rare case of an epignathus in which the intracranial lesion was encapsulated and did not invade the brain. These rare but important findings will provide additional, potential therapeutic strategies for gynecologists, neurosurgeons, and pathologists.

Abstract
Background The incidence of radiation-associated angiosarcoma (RAA) of the breast has been increasing, and its prognosis is reportedly poor. It is important to remove tumor tissues completely to prevent recurrence. Case presentation We report two cases of patients with RAA of the breast. Both patients had a nodule in their remaining breast a few years after undergoing breast-conserving surgery and radiation therapy for breast cancer. The nodules were diagnosed as angiosarcoma by skin biopsy and open biopsy, respectively. To determine the extent of lesion spread, mapping biopsy was performed before surgery. Both patients underwent mastectomy, extensive skin resection, and split skin grafting. Pathological findings showed that their tumors could be completely resected. After surgery, chemotherapy was performed. Conclusion In our cases, no local or distant recurrence has been detected in either patient for over 4 years. We identified the range of tumor invasion by preoperative mapping biopsy and completely resected all tumor tissue.

Abstract
Pancreatic cancer is still a disease of high mortality despite availability of diagnostic techniques. Mucins (MUC) play crucial roles in carcinogenesis and tumor invasion in pancreatic neoplasms. MUC1 and MUC4 are high molecular weight transmembrane mucins. These are overexpressed in many carcinomas, and high expression of these molecules is a risk factor associated with poor prognosis. We evaluated the methylation status of MUC1 and MUC4 promoter regions in pancreatic tissue samples from 169 patients with various pancreatic lesions by the methylation specific electrophoresis (MSE) method. These results were compared with expression of MUC1 and MUC4, several DNA methylation/demethylation factors (e.g. ten-eleven translocation or TET, and activation-induced cytidine deaminase or AID) and CAIX (carbonic anhydrase IX, as a hypoxia biomarker). These results were also analyzed with clinicopathological features including time of overall survival of PDAC patients. We show that the DNA methylation status of the promoters of MUC1 and MUC4 in pancreatic tissue correlates with the expression of MUC1 and MUC4 mRNA. In addition, the expression of several DNA methylation/demethylation factors show a significant correlation with MUC1 and MUC4 methylation status. Furthermore, CAIX expression significantly correlates with the expression of MUC1 and MUC4. Interestingly, our results indicate that low methylation of MUC1 and/or MUC4 promoters correlates with decreased overall survival. This is the first report to show a relationship between MUC1 and/or MUC4 methylation status and prognosis. Analysis of epigenetic changes in mucin genes may be of diagnostic utility and one of the prognostic predictors for patients with PDAC.

Abstract
Lung cancer remains a disease of high mortality, despite advanced diagnostic techniques. Mucins (MUC) play crucial roles in carcinogenesis and tumor invasion in lung neoplasms. Our immunohistochemistry (IHC) studies have shown that high MUC4 expression correlates with a poor outcome. We have also shown that the expression of several mucin genes in cancer cell lines is regulated by DNA methylation. We evaluated the expression level of MUC4, mRNA and several DNA hypomethylation factors in lung tissue samples from 33 patients with various lung lesions. The results indicated that the DNA methylation status of MUC4 matched the expression level of mRNA. In addition, the TET1 (Ten-Eleven Translocation) mRNA showed a significant correlation with the status of DNA methylation of MUC4. Furthermore, the treatment of a lung cancer cell line with TET1 siRNA caused a reduction in MUC4 mRNA expression. Thus, we suggest that TET1 mediated DNA hypomethylation plays a key role in the expression of MUC4. This is the first report that TET1 mediated DNA hypomethylation regulates the expression of MUC4 in lung cancer. The analysis of these epigenetic changes may be useful for diagnosing carcinogenic risk.

Abstract
We herein present an autopsy case of a glioma patient who received long-term treatment with temozolomide (TMZ). The patient, a 35-year-old man with a hypointense tumor of the left frontal lobe, without contrast enhancement following gadolinium (Gd) administration on T1-weighted images, underwent tumor removal surgery, after which the tumor was diagnosed as anaplastic astrocytoma. By the third round of surgery, the tumor had progressed to anaplastic astrocytoma with contrast enhancement following Gd administration, and the patient received 60 Gy of external beam radiotherapy and nimustine hydrochloride (ACNU)-based chemotherapy. After the fifth tumor removal surgery, TMZ was substituted with ACNU chemotherapy, which suppressed tumor progression. Following the 41st TMZ treatment, hemorrhage was observed in the residual tumor, and the hematoma had been replaced by a hemangioma. The hemangioma and surrounding brain tissue was removed during the sixth surgery. The patient survived for 14 years and 9 months after the initial surgery, but succumbed to hydrocephalus due to bleeding from hemangiomas. The histopathological specimens of the first to the sixth surgeries revealed mutant isocitrate dehydrogenase 1 (IDH1; R132H point mutation) and p53-positive tumor cells, but cells positive for the R132H mutation or p53 could not be detected by immunohistochemistry in the autopsy specimens of the brain after 108 courses of TMZ treatment. Mutant IDH1 (R132H) cells were also not detected in the autopsy specimens of the brain by polymerase chain reaction analysis.

Abstract
Mucins play pivotal roles in influencing cancer biology, for example affecting carcinoma invasion, aggressiveness and/or metastatic potential. Our aim is to investigate the significance of expression profiles of two mucins in particular, MUC1 and MUC2, their correlations with various clinicopathological features, and prognosis in gallbladder adenocarcinoma (GBAC). We performed immunohistochemistry from patients with surgically resected GBAC, using antibodies against mucin core proteins MUC1/DF3 and MUC2/Ccp58 in 81 paraffin-embedded tumor samples. MUC1 or MUC2 expression was considered to be high when ≥ 20% or 10% of the GBAC cells showed positive staining, respectively. High MUC1 expression was revealed to have a significant relationship to the presence of pathologically lymphatic and vascular invasion, and regional lymph node metastasis. By contrast, high MUC2 expression showed a significant correlation with pathologically perineural invasion, T stage ≥ 3, and post-operative recurrence. Moreover, MUC1 showed significantly positive co-expression and potentially complementary correlations with MUC2. Multivariate analyses demonstrated that the high MUC1 expression group had significantly shorter disease-specific survival times. However, the combination of both high MUC1 and MUC2 expression did not predict worse outcome in GBACs. Therefore, although each mucin has a somewhat important role in the pathogenesis of GBAC progression, MUC1 can independently predict vessel invasion and poor prognosis in patients with GBAC. The detection of MUC1 might well offer a useful parameter for providing clinical management and treatment against postsurgical GBACs.

Abstract
Pulmonary alveolar proteinosis (PAP) is a rare pulmonary disease characterized by alveolar accumulation of surfactant lipids and proteins. It is usually autoimmune and secondary to hematologic malignancy or infection. To date, only 5 case reports of PAP associated with lung cancers, including 2 cases of squamous cell carcinoma and 3 cases of adenocarcinoma, have been published. To the best of our knowledge, no case of PAP with small cell lung carcinoma has been reported thus far. We herein report the first case of PAP associated with small cell lung carcinoma.
