Abstract
OBJECTIVE To explore the significance of intraoperative sentinel lymph node (SLN) identification in endometrial cancer. METHODS We retrospectively analyzed the clinical data of 56 patients with intraoperative SLN recognition (group A) and 50 patients without intraoperative SLN recognition (group B). SLN and pelvic abdominal lymph node distribution, SLN recognition rate, SLN recognition effect, mortality, the incidence of adverse events, and cumulative survival rate were statistically analyzed. RESULTS SLN were identified and removed in 41 of the 56 patients, with a recognition rate of 82.14% (46/56). The sensitivity of SLN was 83.72%, the specificity was 84.62%, and the negative predictive value was 61.11%. There were 15 patients with no SLN metastasis found in the pathological examination during the operation, among which two patients with poorly differentiated adenocarcinoma and clinical stage II patients underwent immunohistochemical staining, and three patients showed SLN micro-metastasis but no cancer tissue metastasis in the lymph node dissection. There was no significant difference in the incidence of total adverse events between group A and group B (P>0.05). The cumulative survival rate of group A was higher than that of group B (P=0.018). CONCLUSION Intraoperative SLE identification can avoid false negative results, is safe and feasible, and can prolong the survival time of patients with endometrial cancer.

Abstract
BACKGROUND Gastric teratoma (GT) occurs as a rule in infancy and is an extremely unusual gastric tumor in adult patients. CASE PRESENTATION In this paper, we present the clinical and imaging findings of a 56-year-old female patient with a GT. The patient's main symptoms were increasing abdominal discomfort and pain. After the physical examination, she underwent ultrasound (US) and computed tomography (CT), which showed a large mass at the posterior wall of the stomach, and a teratoma was initially considered. After surgery, pathology confirmed the diagnosis of GT. The patient recovered after surgery and was discharged in good health. To the best of our knowledge, this study is the first reported case of gastric teratoma in an adult woman in the literature. CONCLUSION Gastric teratoma of the adult period is a rare benign neoplasm that may have several complications; therefore, imaging is crucial for diagnosis and accurate treatment management. The aim of this study is to emphasize the value of US and CT in the diagnosis and treatment monitoring of mature gastric teratomas.

Abstract
Myoepithelioma, also known as malignant myoepithelioma, is a rare malignant tumor originating from myoepithelial cell. This article reports a patient with a huge tumor in the neck and left elbow who underwent fine needle aspiration under local anesthesia. The pathological diagnosis was a myoepithelioma. Under general anesthesia, giant tumors in the lower neck, posterior cranial fossa, neck, and left elbow were removed, and postoperative pathology showed that they were all myoepithelial tumors. Immunohistochemistry showed AE1/AE3 (+), P63 (+), CK7 (+), CK5 (+), and CD138 (+). The clinical characteristics and diagnosis and treatment process of this case are reported and relevant literature is reviewed.

Abstract
INTRODUCTION Surgery is the primary treatment modality for oral squamous cell carcinoma. The purpose of the surgical procedure is complete removal of the tumor with a sufficient margin of healthy tissue in its surroundings. Resection margins represent an important factor for planning further treatment and for estimation of the disease prognosis. Resection margins can be divided into negative, close and positive. Positive resection margins are considered a prognostically unfavorable factor. However, the prognostic significance of close resection margins is not entirely clear. The aim of this study was to evaluate the relationship between resection margins and disease recurrence, disease-free survival and overall survival. MATERIAL AND METHODS The study included 98 patients who underwent surgery for oral squamous cell carcinoma. During histopathological examination, resection margins of each tumor were evaluated by a pathologist. The margins were divided into negative (> 5 mm), close (0-5 mm), and positive (0 mm). Disease recurrence, disease-free survival and overall survival were evaluated according to the individual resection margins. RESULTS Disease recurrence occurred in 30.6% of patients with negative, 40.0% with close, and 63.6% with positive resection margins. Significantly shorter disease-free survival and shorter overall survival in patients with positive resection margins was proven. The five-year survival rate was 63.9% in patients with negative, 57.5% with close, and only 13.6 % with positive resection margins. The risk of death was 3.27times higher in patients with positive resection margins compared to patients with negative resection margins. DISCUSSION Positive resection margins represent a negative prognostic factor, which was also confirmed in our study. There is no unequivocal consensus on the definition of close and negative resection margins and also on the prognostic significance of close resection margins. Factors that may contribute to inaccuracy in the evaluation of resection margins include tissue shrinkage after excision and after fixation of specimens before the histopathological examination. CONCLUSION Positive resection margins were associated with a significantly higher incidence of disease recurrence, shorter disease-free survival and shorter overall survival. When comparing the incidence of recurrence, disease-free survival, and overall survival between patients with close and negative resection margins, the differences were not statistically significant.

Abstract
Coronary aneurysm secondary to coronary fistula is a rare condition, with no existing report on its pathological examination. We report the case of a patient diagnosed with a right coronary artery fistula with coronary aneurysm during the fetal period. During follow-up after delivery, the aneurysm became larger, even though the shunt size decreased. We were afraid the aneurysm would rupture and therefore, planned elective catheter embolization. At the age of 4 years, the patient underwent surgery, which involved closing the fistula and making the lumen of the aneurysm smaller. However, the surgery was not catheter embolization as planned because segment 3 branched off from the largest aneurysm where we planned to embolize. Pathologically, the structure of the coronary artery differed from that of a healthy one, with thickened intima and media, fewer scattered smooth muscle cells, widely distributed elastic fibers, and mucoid degeneration in the media. The structure of the coronary artery suggested that the vessel wall was weak and that the aneurysm would rupture if not treated. Postoperative coronary angiography showed that segment 2 was obstructed, while the collaterals from the left coronary artery perfused the area. We could have treated the fistula with a catheter as scheduled.

Abstract
Pancreatic cancer is not easy to detect at its early stages due to difficulties in identifying symptoms at these stages. As it progresses, abdominal pain, loss of appetite, abdominal distension, jaundice and pain in the back, especially the lower back, might develop. Moreover, sudden onset or worsening of diabetes mellitus may be seen, which often prompts screening for the detection of pancreatic cancer. Since it rapidly spreads to surrounding tissues and organs, pancreatic cancer has a poor prognosis. However, metastasis to the bladder is rare, with few cases diagnosed on the basis of detecting gross hematuria. The current study presents a case of gross hematuria and exacerbated diabetes in a 90-year-old woman. Cystoscopy revealed a non-papillary tumor in the posterior bladder wall. Pathological examination of bladder tumor specimens obtained via transurethral resection revealed adenocarcinoma. Subsequent systemic examinations revealed primary pancreatic cancer that had metastasized to the bladder. To the best of our knowledge, this is the second reported case of pancreatic cancer diagnosed based on the detection of gross hematuria due to bladder metastasis, since 1992.

Abstract
Extracardiac rhabdomyomas are rare benign tumors showing skeletal muscle differentiation. They can be divided into adult, fetal, and genital subtypes. Fetal rhabdomyomas are rarer than the adult subtype and although usually diagnosed at birth, the diagnosis is based on histology rather than patient age. We present a rare case of a 25-year-old man with a cellular fetal (juvenile) rhabdomyoma, found in the postcricoid region of the hypopharynx.

Abstract
Approximately 0.17-2% of mature cystic teratomas undergo malignant transformation, of which squamous cell carcinoma (SCC) is the most common, accounting for 80% of these cases. Urothelial malignant transformation is extremely rare. The present study involves a 58-year-old patient who visited the hospital with discomfort in the lower abdomen. USG and pelvic MRI showed a left ovarian mature cystic teratoma. Left salpingo-oophorectomy was performed, and pathological examination revealed urothelial carcinoma transformation of the mature cystic teratoma morphologically and immunohistochemically. No metastasis to other organs was identified by CT after the surgery. Additional surgery, including total hysterectomy, right salpingo-oophorectomy, omentectomy, and dissection of pelvic and para-aortic lymph nodes, was performed without complications. No tumors were identified elsewhere, and the patient's stage was confirmed as IA. She had an uneventful postoperative course and was discharged 10 days later. CT showed no metastasis or recurrence six months later.

Abstract
Pancreatic cancer is a highly malignant digestive system tumor with a poor prognosis. Most pancreatic cancer patients are diagnosed at an advanced stage or even metastasis due to its highly aggressive characteristics and lack of typical early symptoms. Thus, an early diagnosis of pancreatic cancer is crucial for improving its prognosis. Currently, screening is often applied in high‐risk individuals to achieve the early diagnosis of pancreatic cancer. Fully understanding the risk factors of pancreatic cancer and pathogenesis could help us identify the high‐risk population and achieve early diagnosis and timely treatment of pancreatic cancer. Notably, accumulating studies have been undertaken to improve the detection rate of different imaging methods and the diagnostic accuracy of endoscopic ultrasound‐guided fine‐needle aspiration (EUS‐FNA) which is the golden standard for pancreatic cancer diagnosis. In addition, there are currently no biomarkers with sufficient sensitivity and specificity for the diagnosis of pancreatic cancer to be applied in the clinic. As the only serum biomarker approved by the United States Food and Drug Administration, carbohydrate antigen 19‐9 (CA19‐9) is not recommended to be used in the early screening of pancreatic cancer because of its limited specificity. Recently, increasing numbers of studies focused on the discovering of novel serum biomarkers and exploring their combination with CA19‐9 in the detection of pancreatic cancer. Besides, the application of liquid biopsy involving circulating tumor cells (CTCs), circulating tumor DNA (ctDNA), microRNAs (miRNAs), and exosomes in blood and biomarkers in urine, and saliva in pancreatic cancer diagnosis are drawing more and more attention. Furthermore, many innovative technologies such as artificial intelligence, computer‐aided diagnosis system, metabolomics technology, ion mobility spectrometry (IMS) associated technologies, and novel nanomaterials have been tested for the early diagnosis of pancreatic cancer and have shown promising prospects. Hence, this review aims to summarize the recent progress in the development of early screening and diagnostic methods, including imaging, pathological examination, serological examination, liquid biopsy, as well as other potential diagnostic strategies for pancreatic cancer.

Abstract
Malignant peripheral nerve sheath tumor (MPNST) is a rare disease. The present study discusses the case of a 30-year-old male patient who presented with complaints of pain in the left testis and groin over 1 month. Ultrasonography and computed tomography (CT) imaging revealed the presence of a space-occupying lesion localized in the left testis. The mass was completely resected using an open surgical approach and was diagnosed as a primary MPNST of the left testis on postoperative histopathological examination. As this type of tumor is rare, there is currently no standard diagnostic or treatment method for MPNST. Pathological examination, enhanced CT imaging and immunohistochemical investigation are helpful for establishing the diagnosis and surgical resection is considered to be an effective treatment.

Abstract
AIM To investigate the clinical manifestations, diagnostic approaches, treatments, and outcomes of intraocular lymphoma. METHODS In this retrospective study, 16 patients (28 eyes) with intraocular lymphoma were recruited in the Department of Ophthalmology, Peking Union Medical College Hospital, from 2004 to 2019. All patients underwent comprehensive ophthalmic examinations. Vitreous specimens of 13 patients were sent for cytopathology examination and other adjunctive diagnostic procedures. Three patients were diagnosed with intraocular lymphoma according to analysis of the histopathological results of systemic lymphoma by one clinician. Twenty-three eyes were treated with intravitreal administration of methotrexate, 4 eyes could not receive ocular treatment due to life-threatening lymphoma, and 1 eye did not require ocular treatment because the fundus lesions regressed after systematic chemotherapy. RESULTS In 28 eyes, 25 eyes were diagnosed with vitreoretinal lymphoma, and 3 eyes were diagnosed with ciliary body lymphoma, all of which were non-Hodgkin diffuse large B cell lymphomas. The final visual acuity improved in 15 eyes (54%), remained unchanged in 5 eyes (18%), and decreased in 8 eyes (29%). Anterior segment inflammation disappeared or reduced in 8 and 5 eyes, respectively; and 15 eyes had no anterior segment reaction. Twenty eyes had mild vitreous opacity, 1 eye had mild vitritis, and 7 eyes had pars plana vitrectomy combined with silicone oil tamponade. Fundus lesions disappeared in 9 eyes and were relieved in 5 eyes; 4 eyes showed no changes, and the remaining 10 eyes' fundus were normal. CONCLUSION The clinical manifestations of intraocular lymphoma are diverse, and the misdiagnosis rate is high. Cytopathological analysis of vitreous is one of the gold standards for the diagnosis. Immunohistochemistry, gene rearrangement and flow cytometric immunophenotypic analysis can improve the diagnostic rate. Ocular chemotherapy or radiotherapy regimens may preserve visual acuity, and a multidisciplinary team can provide individualized treatment for the patients.

Abstract
Background Accurate assessment of regional lymph node (LN) status is essential for the treatment of head and neck squamous cell carcinoma (HNSCC) patients. In this study, we aimed to compare the difference between intravenous injection of indocyanine green (ICG) and peritumoral injection of ICG in the location of metastatic LNs. Methods Twenty-nine patients were enrolled in this study with 13 patients receiving intravenous injection of ICG and 16 patients receiving peritumoral injection of ICG. During the surgery, the fluorescence-positive LNs in vivo were sent to undergo frozen section after fluorescence intensity was recorded. After the cervical LN dissection, all LNs were sorted by region, and the fluorescence intensity was recorded before the LNs were sent for paraffin section. Results During the surgery, both intravenous or peritumoral injections with near-infrared (NIR) fluorescence imaging of ICG had their respective pros and cons in vivo, with the sensitivity and specificity being 62.5%/75% and 98.1%/89.1% respectively. After the surgery, both methods could reduce the pathological workload by preselecting the LNs at-risk in the premise of accurate assessing the cervical LN stage. However, intravenous ICG administration was more valuable in determining all types of LN status according to the fluorescence intensity [area under the curve (AUC): 0.91 vs. 0.78, P<0.001]. Conclusions With the assistance of NIR fluorescence imaging using ICG, both administration methods could reduce the postoperative complication and the pathological workload, whereas the intravenous mode of ICG administration is superior in application value.

Abstract
Batch safety tests (BSTs) of veterinary vaccines are conducted using small laboratory animals to assure the safety of vaccines according to several criteria, including clinical signs and change in body weight. Although the latter is used as an evaluation index in BSTs, there have been no reports on the internal changes that affect body weight during the test period. Therefore, we analyzed BST via pathological examination of the tested animals. Here, BSTs were performed for 176 batches using mice and 126 batches using of guinea pigs. Most of the gross findings could be classified into four lesion types (nodules, adhesions, ascites, no apparent signs), with only one vaccine inducing lesions that could not be classified into any of these four types. Histopathological examination revealed that the reactions caused by BST were pyogenic and/or granulomatous inflammation. Nodular or adhesive lesions comprised more severe pyogenic granulomatous inflammation than ascites or cases with no apparent gross lesions. These nodular or adhesive lesions were more frequently induced by vaccines that contained an adjuvant than by vaccines that did not contain an adjuvant. The cases with "exceptional" gross findings histologically presented severe necrosis of the hematopoietic system. Additional testing showed that these "exceptional" lesions were induced when a specific type of light liquid paraffin was injected along with other vaccine additives. Our results show that body weight loss and/or lesions during BST were induced by proinflammatory properties of the tested vaccines and that BST is a sensitive method for detecting unexpected effects of vaccine components.

Abstract
BACKGROUND Although pilonidal sinus disease is common, development of associated malignancy is very rare. After surgical treatment, most surgeons send the excision material for a histopathological examination. The aim of this study was to examine whether it is necessary to routinely send the pilonidal sinus surgical excision material for this examination. METHOD The data of 3146 patients were retrospectively screened, and 2486 patients with available histopathological reports of the excision material were included in the study. RESULTS Of the 2486 patients included in the study, 2165 were men and 321 were women, and 94.7% of the patients were under the age of 50 years while 5.3% were 50 years or above. The rate of patients who underwent surgery due to recurrence was 1.2%. No malignancy was detected in any patient after the histopathological examination. DISCUSSION In this study, none of the pathology results was reported as malignant. This confirms that it is necessary to ask the question whether we should routinely send the surgical excision material for a histopathological examination.

Abstract
PURPOSE Xanthomatous hypophysitis (XHP) is an extremely rare form of primary hypophysitis for which there is a lack of clinical experience. A comprehensive understanding of its clinical characteristics, diagnosis and treatment is needed. METHODS Here, we report a case study and conduct a systematic review of XHP. Thirty-six cases were included, and their clinical manifestations, endocrine assessment, imaging features, treatment and follow-up data were collected and analyzed. RESULTS The mean age at diagnosis was 39.1 years, and females were predominant (75.0%). The most common symptom was headache (68.6%), and 66.7% of female patients presented menstrual disorders. The most common pituitary dysfunction was growth hormone (GH) deficiency. More than half of patients exhibited central diabetes insipidus (CDI). The majority of patients had an imaging presentation of a cystic lesion with peripheral enhancement. Pituitary stalk thickening was observed in half of the patients. Total lesion resection was achieved in 57.1% of cases. The recurrence rate after partial resection and biopsy was significantly higher than that after total lesion resection (57.1% vs. 0.0%, P = 0.0147). The most common pituitary hormone abnormalities to resolve after surgery were hyperprolactinemia (100.0%) and GH deficiency (91.7%). The typical pathological feature was inflammatory infiltration of foamy histiocytes, which showed positivity for CD68. CONCLUSION Diagnosis of XHP is difficult when relying on clinical symptoms and imaging features. Therefore, surgical histopathology is necessary. Based on the available evidence, total lesion resection is recommended for treatment. However, the long-term prognosis for this rare disease remains unclear.

Abstract
Benign giant renal schwannoma is rarely found and the diagnosis difficulty only depends on physical and imagological examination. Pathological examination is essential to confirm the diagnosis of renal schwannoma. Nephrectomy and tumorectomy are primary treatments for renal schwannoma. Although most of the reported patients present satisfactory outcome, however, there is still not sufficient evidence to reveal the biological characteristics and post-operation recurrence rate of renal schwannoma. Herein, we report a rare case of giant and complicated renal schwannoma. A 56-years-old female patient was admitted to the urology department due to left lower back pain for approximately 5 days. No positive signs and other special abnormalities were found. CT scan presented a soft tissue tumor with inhomogeneous enhanced in the renal hilum. Surgery was performed to excise the tumor and left renal. Renal schwannoma was confirmed by pathological examination. At the 6-month follow-up, no evidence of recurrence was found. Our present report could provide more material for further study.

Abstract
Background A positive surgical margin (PSM) following oral cancer resection results in local recurrence and poor prognosis. Mono-block tumor specimens, especially from the tumor base, are difficult to evaluate. This inaccurate sampling ultimately leads to a false pathological diagnosis. Lugol’s iodine (I2-IK)-enhanced micro-CT is an emerging method to image tumor specimens. This study explores the feasibility of I2-IK-enhanced micro-CT to evaluate the surgical margin for tongue squamous cell carcinoma (TSCC) specimens and to further seek optimal staining parameters. Methods Rabbit tongue tissues and human TSCC samples were imaged via I2-IK-enhanced micro-CT. The optimal I2-IK concentration and staining time were determined before clinical application using tissue shrinkage, micro-CT image quality, and effect on pathological diagnosis as assessment criteria. Next, 6 TSCC specimens were used to verify the process feasibility of surgical margin imaging with the optimal parameters. Finally, the possible reason by which I2-IK could enhance micro-CT imaging was validated in vitro. Results I2-IK staining influenced specimen shrinkage, micro-CT image quality, and pathological image quality in a concentration- and time-dependent manner. After comprehensively considering these indicators, 3% I2-IK staining for 48 and 12 h were found to be optimal for rabbit tongue tissues and TSCC samples, respectively. This method could provide a detailed 3-D structure of TSCC samples compared with H&E sections. Moreover, tumor and normal tissues could be differentiated by their glycogen content, which has high affinity with I2-IK. Conclusions I2-IK-enhanced micro-CT could, thus, indicate the tumor margin and assist pathological sampling in patients with TSCC postoperation.

Abstract
A diaphragmatic tumor is usually caused by metastasis from lung cancer, malignant mesothelioma, and malignant thymoma. Endometrial cancer is rarely involved in metastasis to the diaphragm. A right anterior mediastinal tumor was found in a 60-year-old woman who was initially diagnosed with endometrial carcinoma. There was initially no relationship between the right anterior mediastinal tumor and endometrial carcinoma. Radical curative surgery was performed for endometrial carcinoma. The endometrial carcinoma stage was IA. The patient was admitted to the Department of Thoracic Surgery 6 months after the curative surgery. Intraoperative exploration showed a tumor growing in the right diaphragm. Right diaphragmotomy was performed. Immunohistochemistry showed metastasis of endometrial carcinoma to the diaphragm. Endometrial cancer solitary metastasis to the diaphragm is rare. Clinicians should be aware of this possibility. Surgical treatment followed by a pathological examination is the most useful method for determining the diagnosis of a diaphragmatic tumor due to metastasis of endometrial cancer.

Abstract
Purpose This study compared intraocular toxicity of intravitreally injected povidone-iodine (PI) and polyvinyl alcohol-iodine (PAI) in rabbits. Methods In each rabbit, 0.1 mL of PI or PAI solution was injected intravitreally into one eye and saline was injected into the other. PI was tested at available iodine concentrations of 0.05%, 0.1%, 0.2%, and 0.5%, and PAI at 0.05%, 0.1%, and 0.2% (n = 6 each). Electroretinograms were recorded before injection and 1, 7, and 14 days after injection. Pathological examinations of eyeballs were performed on day 15. Results Mean b-/a-wave ratios of the electroretinograms did not change in eyes injected with 0.05%, 0.1%, or 0.2% PI (PI-0.05, PI-0.1, and PI-0.2, respectively) or in eyes injected with 0.05% or 0.1% PAI (PAI-0.05 and PAI-0.1, respectively) compared to saline-injected eyes, but was transiently impaired on day 1 in PAI-0.2 eyes. Histopathologically, no retinal abnormalities were observed in PI-0.05, PAI-0.05, or PAI-0.1 eyes. One PI-0.1 eye first showed localized inflammatory cell infiltration in the inferior retinal region. Two PI-0.2 eyes and one PAI-0.2 eye had retinal degeneration and inflammatory cell infiltration. In the PI-0.5 group, extensive inflammatory cell infiltration was observed in six eyes and inferior retinal detachment in five eyes. Conclusions PI and PAI have equivalent retinal toxicity profiles, and retinal toxicity first affects the inner retinal layer in the inferior region. The highest non-retinotoxic vitreous concentration is 0.0033% available iodine from intravitreal injection of PI or PAI containing 0.05% available iodine. Translational Relevance Low concentrations of PI or PAI can be used to wash the ocular surface during surgery or intravitreal injection to prevent endophthalmitis.

Abstract
Severe neonatal gastrointestinal diseases such as necrotizing enterocolitis or spontaneous intestinal perforation are potentially lethal conditions which predominantly occur in preterm infants. Cytomegalovirus (CMV), which is known to cause congenital and acquired infections in the newborns, has also been implicated in such severe gastrointestinal diseases in premature infants. However, the pathogenic role of CMV and effect of antiviral therapy in severe gastrointestinal disease in premature neonates is currently unclear. We present an infant, born at 26-weeks' gestation, presented with progressive dyspepsia and abdominal distention after the closure of the symptomatic patent ductus arteriosus at the day of life (DOL) 4, requiring the emergent surgery for ileal perforation at the DOL8. After the surgery, abdominal symptoms persisted and the second emergent surgery was performed for the recurrent ileal perforation at DOL17. Even then the abdominal symptoms prolonged and pathological examination in the affected intestine at the second surgery showed CMV inclusion body. Immunoreactivity for CMV antigen was detected in the specimen at the first surgery on DOL8. Blood and urinary CMV-DNA were detected at DOL28. CMV-DNA was also detected in the dried umbilical cord which was obtained within a week from birth. A 6-week course of intravenous ganciclovir (12 mg/kg/day) was started at DOL34 and then symptoms resolved along with decreasing blood CMV-DNA. Pathological findings characteristic of CMV were not detected in the resection specimen at the ileostomy closure at DOL94. These observations indicate that anti-CMV therapy may be beneficial for some premature infants with severe CMV-associated gastrointestinal diseases and warrants further studies focusing on pathogenic role, diagnosis, treatment and prevention of this underrecognized etiology of severe gastrointestinal diseases particularly in premature neonates.

Abstract
Background Uterine leiomyoma is the most common benign tumor in women. Uterine sarcoma, though with very low incidence, has a high malignant degree and poor prognosis. It has difficulties in preoperative diagnosis, frozen pathological examination and postoperative treatment. Case report A 49-year-old woman presented with menstrual disorder. Magnetic resonance imaging showed a huge uterine mass. The patient underwent laparoscopic hysterectomy and part of the uterine tissue looked like fish. Specimens were sent to frozen pathological examination for four times, but none of the results showed malignancy certainly. Considering all abnormalities, we removed the uterine through vagina completely rather than morcellation and did pelvic lymph node biopsy. Postoperative pathological examination revealed uterine leiomyosarcoma and one pelvic lymph node had metastasized. Conclusion Uterine sarcoma is difficult to be diagnosed even frozen pathological examination has been performed. Unexpected uterine sarcoma should always be considered, and precautions should be taken if we find anything suspicious. Fortunately, the patient has avoided second operation.

Abstract
Gastric teratoma primarily occurs within 3 months following birth, and is a rare pattern of gastric lesion in adult patients. The present study reports the case of a 60-year-old male patient who was diagnosed with a tumour in the lesser curvature within the gastric cardia area, which grew outside the cavity, invaded into the duodenal bulb and formed a gastroduodenal fistula. Briefly, initial gastroscopy upon hospital admission revealed mucosa bulging into the gastric cavity, gastric ulcer and duodenal bulb mucosal congestion with oedema. Subsequent computed tomography scans showed lesser curvature-occupying hamartoma in the gastric cardia area, and upper gastrointestinal angiography confirmed gastric stromal tumour complicated with cardia duodenal fistula. Total gastrectomy followed by Roux-en-y oesophagojejunostomy was performed, and pathology analysis of the tissue specimen confirmed mature gastric teratoma. The formation of a gastroduodenal bulb fistula with the tumour as a bridge is a rare phenomenon. A notable finding of the present case study was that the final diagnosis of gastric teratoma mainly depended on pathological examination.

Abstract
Pulmonary lymphangioleiomyomatosis is a rare disease that presents with diffuse progressive destruction of the pulmonary parenchyma. The incidence is less than 1 per million. No effective treatments are currently proposed for this disease. A 29-year-old woman who was diagnosed with pulmonary lymphangioleiomyomatosis received excisional biopsy and symptomatic supportive care. She was diagnosed with pulmonary lymphangioleiomyomatosis and was treated with anti-estrogen therapy and symptomatic supportive care. Pulmonary lymphangioleiomyomatosis is a very rare tumor that cannot be effectively cured.

Abstract
Trisomy 13 or Patau syndrome (PS) is a well-known aneuploidy characterized by a polymalformative syndrome. We described a large series of fetuses with PS and compared them with cases described in the literature, most of which were live-born. In all, 42 fetuses, aged from 14 to 41 gestational weeks (GW), were examined. The main defects observed were similar to those described in live-born patients: congenital heart defects (76%), holoprosencephaly spectrum anomalies including arhinencephaly and hypotelorism (74%), urinary tract anomalies (71%), ear anomalies (69%), postaxial polydactyly (67%), anogenital anomalies (60%), anophthalmos, and/or microphthalmos (53%), brachycephaly (45%), and oro-facial clefts (45%). A duplication or triplication of at least one distal phalanx of the thumb or hallux was present in 38% of fetuses. This sign has only been reported previously in one patient in the literature. Fetal examination in trisomy 13, is thus, useful to complete the phenotype or to orient diagnosis toward trisomy 13 in the absence of cytogenetic analysis.

Abstract
Objective: To study the correlation between the BRAF V600E mutation and the clinicopathological features of papillary thyroid carcinoma(PTC), and to explore the application value of BRAF V600E mutation in PTC. Method: The BRAF V600E gene mutation was detected in 108 PTC cases and 30 control cases by qPCR. The results were statistically analyzed by using SPSS 21.0 software. Result: The BRAF V600E mutation was absent in the control group. The BRAF V600E mutation rate was 72.20% in 108 PTC cases. Compared with patients with wild type,the mean age of patients with the mutant BRAF V600E was significantly older(P<0.05). BRAF V600E mutations were associated with PTC tissue subtypes and central area lymph node metastasis(P<0.05). BRAF V600E mutations were not correlated with tumor diameter, patient gender, multifocality, tumor site, concomitant disease, lymph node metastasis in side region of neck, capsule invasion, and TNM staging(P>0.05). Conclusion: The value of BRAF V600E mutation in the prognosis of PTC remains to be studied. BRAF V600E mutation is of value for pathological diagnosis of PTC.

Abstract
BACKGROUND AND OBJECTIVES Tumors of the splenic flexure (TSF) can be associated with metastatic lymph nodes (LN) along the left colic pedicle, but also along the superior mesenteric vessels. We aimed to detail the anatomical distribution of metastatic LNs in patients undergoing elective subtotal colectomy for TSF. METHOD Between 2000 and 2016, 65 patients were included. At pathological analysis, LNs were classified into two groups: locoregional LN (along the left colic artery) and distant LN (along the middle colic, right colic, and ileocolic arteries). RESULTS The median number of LNs examined was 20. Eighteen patients (27%) were pN+. Among them, six (33% of pN+ patients and 9% of the series) had at least one positive distant LN. All these patients had a positive distant LN along the right colic artery. These patients had a significantly advanced stage and more positive LNs than the others (stage III-IV: 100% vs 22%, P = 0.0009 and 6 [3-15] vs 0 [0-15], P < 0.0001, respectively). The presence of synchronous metastases was predictor of metastatic distant LNs (P = 0.042). CONCLUSION Elective subtotal colectomy for TSF allows to discover distant positive LNs in nearly 10% of patients. For those having TSF and synchronous metastatic disease enable to resection, subtotal colectomy should be recommended.

Abstract
The article presents a comparative analysis of the results of in vivo scanning of oral mucosa leukoplakia with optical coherence tomography (OCT) method and pathological studies in 15 patients (9 females and 6 males aged 27-82). The study revealed specific OCT signs of leukoplakia: even disorder of tissue layering and less clear visualization of lamina propria. OCT is an important stage in the differential diagnosis of leukoplakia of the oral mucosa and significantly complements the clinical and pathomorphological study.

Abstract
Increasing prostate cancer incidence rates highlight the importance of more timely diagnosis with the ultimate aim of reducing cancer-specific mortality, while maintaining patients quality of life. Until recently, digital rectal examination and prostate-specific antigen have been used for diagnosis of prostate cancer. Recent advances in medical technologies and laboratory testing have led to introducing new cancer markers into clinical practice. The most highly demanded of them are the PCA-3, -2proPSA and Prostate Health Index. Despite the wide range of laboratory tests, a prostate biopsy with a subsequent morphological examination of biopsy tissue specimens remains the only way to definitively diagnose prostate cancer.

Abstract
The College of American Pathologists guidelines recommend examining at least four representative tumor blocks for determining pathological T stage in patients with primarily resected esophageal cancer. Whether the same pathological requirements are adequate in patients undergoing esophagectomy following neoadjuvant chemoradiotherapy (nCRT) remains unclear. We hypothesized that current examination protocols may underestimate the presence of microscopical residual disease after nCRT, potentially leading to under-staging. We retrospectively reviewed the records of patients with esophageal squamous cancer (ESCC) who were diagnosed as having pathological complete response (pCR) following nCRT. The thoroughness of the pathological examination in pCR patients was examined using (i) the number of blocks examined in suspicious tumor area (≤4 vs. >4), and (ii) the block quotient (calculated as the pretreatment tumor length divided by the number of blocks examined in suspicious tumor area). A total of 91 patients were enrolled. The mean number of blocks used to confirm pCR was 4.8 (range: 2-14). The 5-year overall survival (OS) and disease-free survival (DFS) in the entire cohort were 55% and 65%, respectively. Multivariate analyses identified the block quotient as the only independent predictor of OS and DFS. Receiver operating characteristic curve analysis indicated an optimal cutoff value of 1.4 for the block quotient. Among the patients who achieved pCR, the 5-year DFS differed significantly between subjects with a low (≤1.4) or high (>1.4) block quotient (76% vs. 47%, respectively, P = 0.03). The block quotient (calculated by the pretreatment tumor length divided by the number of blocks) - which reflects the meticulousness of the histopathological examination for confirming pCR - is associated with survival in ESCC patients.

Abstract
BACKGROUND The Xpert MTB/RIF assay (Xpert; Cepheid, Sunnyvale, CA, USA) has been widely used for pulmonary and extra-pulmonary tuberculosis (TB) diagnosis. In clinical practice, specimen yielding smear-negative, culture-negative but Xpert-positive results is frequently confronted. Due to the notorious possibility of contamination that molecular tests always been thought of, Xpert-positive results without bacteriological supporting evidence arouse great confusions to clinicians. METHODS A retrospective study was performed. From April 2014 to February 2015, 852 clinical specimens were Xpert-positive. The results of Xpert assay, bacteriological and pathological examinations from either the same specimens or from the specimens collected during same clinical operations were investigated. RESULTS A total of 90 specimens with Xpert-positive but smear-negative and culture-negative results were recruited, and 81 of them were pus specimens collected from Bone and Joint Tuberculosis (BJTB) patients. According to the pathological examination results, 77 of the 81 pus specimens, 8 of 9 other types of specimens were confirmed as either TB or strongly suggestive of TB; three pus specimens and one biopsy tissue were also suggested TB but with less stronger evidence; only one pus specimen was not TB suggestive. CONCLUSIONS Our study demonstrated that Xpert could be trusted for BJTB diagnosis even when no supporting bacteriological evidence is available in high TB prevalence settings. Our results will alleviate the confusion among clinicians in such scenarios.

Abstract
The diagnostic value of contrast-enhanced ultrasound (CEUS) or real-time elastography (RTE) alone, as well as a combination of CEUS and RTE, in distinguishing benign from malignant thyroid nodules was investigated. Between August 2012 and June 2014, a total of 97 consecutive patients (50 male and 47 female patients; mean age, 48.6±12.4; age range, 27-70 years) with thyroid nodules referred for surgical treatment were examined by CEUS and RTE. The final diagnosis was obtained based on histological findings. Image analysis of the CEUS and RTE scans was performed. Considering the postoperative pathological results as the golden standard, a receiver operating characteristic (ROC) curve was constructed. Subsequently, the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of CEUS alone, RTE alone and CEUS + RTE combination were calculated. Pathological examination showed 66 papillary carcinomas and 43 benign lesions, including 21 adenomas and 22 nodular goiters. The sensitivity, specificity, PPV, NPV and accuracy of CEUS were 81.82, 90.70, 93.10, 90.70 and 85.32%, respectively. In the case of RTE, the sensitivity, specificity, PPV, NPV and accuracy were 80.30, 88.37, 91.38, 88.37 and 83.49%, respectively. Furthermore, the combination of CEUS + RTE had a sensitivity of 95.45%, specificity of 95.35%, PPV of 96.92%, NPV of 95.35% and accuracy of 95.41%. Therefore, the CEUS + RTE combination showed a significantly higher sensitivity and specificity compared with CEUS or RTE alone (all P<0.05). Based on ROC analysis, the area under the curve (AUC) for CEUS, RTE and CEUS + RTE combination was 0.883, 0.863 and 0.959, respectively. The AUC of RTE alone was significantly lower compared with that of the CEUS + RTE combination. In conclusion, our results demonstrate that CEUS + RTE combination significantly increases the diagnostic performance for differential diagnosis of malignant and benign thyroid nodules compared with CEUS or RTE alone.

Abstract
AIM To report 7 cases of conjunctival lymphangiectasia, introduce a simple operation method and discuss the result of the pathological examination. METHODS Clinical data including medical history, physical examination, previous surgery history were collected in 7 patients with conjunctival lymphangiectasia. Ocular data including visual acuity, Slit-lamp biomicroscopy were released, as were results of histopathology studies. Surgical method was also introduced by video. RESULTS Seven eyes of 7 patients (4 male and 3 female) with biopsy-proven conjunctival lymphangiectasia underwent the resection. Despite different surgical intervention, the optima method has been founding to treatment conjunctival lymphangiectasia. It is to reduce recurrence that the most concerned problem. In these 7 cases reported, patients kept healthy for 18 months without any one recurrence, whose visual acuity were not affected. Pathological report showed cystic tissue consists of squamous epithelium with significant hyperplasia. CONCLUSION This operation method is simple and easy to complete, as it is deserved to accept for surgeons and patients on the basis of its advantages.
