Abstract
BACKGROUND AND OBJECTIVE Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a diagnostic procedure with adequate performance; however, its ability to provide specimens of sufficient quality and quantity for treatment decision-making in advanced-stage lung cancer may be limited, primarily due to blood contamination. The use of a 0.96-mm miniforceps biopsy (MFB) permits true histological sampling, but the resulting small specimens are unsuitable for the intended applications. Therefore, we introduced a 1.9-mm standard-sized forceps biopsy (SFB) and compared its utility to that of MFB. METHODS We prospectively enrolled patients from three institutions who presented with hilar/mediastinal lymphadenopathy and suspected advanced-stage lung cancer, or those who were already diagnosed but required additional tissue specimens for biomarker analysis. Each patient underwent MFB followed by SFB three or four times through the tract created by TBNA using a 22-gauge needle on the same lymph node (LN). Two pathologists assessed the quality and size of each specimen using a virtual slide system, and diagnostic performance was compared between the MFB and SFB groups. RESULTS Among the 60 enrolled patients, 70.0% were diagnosed with adenocarcinoma. The most frequently targeted sites were the lower paratracheal LNs, followed by the interlobar LNs. The diagnostic yields of TBNA, MFB and SFB were 91.7%, 93.3% and 96.7%, respectively. The sampling rate of high-quality specimens was significantly higher in the SFB group. Moreover, the mean specimen size for SFB was three times larger than for MFB. CONCLUSION SFB is useful for obtaining sufficient qualitative and quantitative specimens.

Abstract
Multifocal dissemination of cancer cells from the primary tumor sites to the subarachnoid, pia mater and cerebrospinal fluid (CSF) of the brain and spinal cord causes carcinomatous meningitis (CM). CM is rarely observed in patients with gynecological cancer. The present study described a 59-year-old woman who was diagnosed with CM as a recurrence of stage IIIC ovarian cancer, after presenting with headache and decreased level of consciousness. During adjuvant therapy following surgical debulking, she developed nausea and vomiting. The post-contrast fluid-attenuated inversion-recovery magnetic resonance imaging showed leptomeningeal enhancement on all sulci, particularly around the falx cerebri and cerebellar hemisphere. CM was suspected and CSF cytology revealed adenocarcinoma cells, thus confirming the diagnosis. Overall, although CM is rare, clinicians should be aware of this complication when patients with malignancies experience neurological symptoms, including headache, nausea and vomiting. Knowledge of this clinical entity should assist clinicians in ascertaining accurate diagnoses.

Abstract
Wilson disease is an inherited copper metabolism disorder. We herein report a novel endoscopic finding in three men with Wilson disease. These patients underwent upper endoscopy due to gastrointestinal symptoms or during follow-up. In each case, endoscopy revealed lustrous white erosions surrounded by an erythematous mucosa in the greater curvature of the gastric body. A biopsy of the lesions showed orcein-positive tissue, indicating copper deposition, in the interstitial stroma and fundic glands of the mucosa. All patients had been receiving treatment with zinc acetate. These endoscopic findings might have been related to the cytotoxicity of the accumulated copper and zinc acetate.

Abstract
Immunoglobulin (Ig) G4-related disease (IgG4-RD) is a group of chronic relapsing inflammatory conditions. Although IgG4-RD can occur in various organs, it is rarely observed in mammary glands. Here, we report a case of IgG4-related mastitis (IgG4-RM) that needed to be differentiated from breast cancer. A 54-year-old woman was examined for a tumor in her left breast. Mammary ultrasonography revealed an irregular hypoechoic tumor measuring 45.0 × 43.0 × 32.0 mm in size. A core-needle biopsy of the left breast tissue revealed a high degree of mixed T and B lymphocytic and plasma cell infiltration, as well as interstitial fibrosis. IgG4-RD was diagnosed based on hematological examination that revealed an abnormal IgG4 value of 332 mg/dl. All the clinical diagnostic criteria for IgG4 were met, resulting in a definitive diagnosis of IgG4-RM.

Abstract
We elucidated clinicopathological characteristics of giant cell tumor of bone (GCTB) in Japan, and significant clinicopathological factors for predicting local recurrence. Clinicopathological profiles of 213 patients with GCTB (100 male, 113 female) involving extra‐craniofacial bones were retrieved. Pathological slides obtained at the initial surgery were reviewed. Fourteen pathological and five clinical features were statistically analyzed to disclose prognostic significance. Patient age ranged from 12–80 years (Average 38.7). Long bones were most frequently affected (86.4%), especially around the knee (62.9%). Histological features are basically similar to those previously reported. Within a follow‐up period (24–316 months, average 106.1 months), the local recurrence rate is 29.1%. Metastasis has occurred in 9 patients. Cox regression analysis of representative clinicopathological features shows that younger age, higher mitotic count, smaller zones of stromal hemorrhage, considerable vascular invasion and absence of ischemic necrosis are significant predictors for local recurrence. Initial operative method (curettage) is a significant risk factor in univariate analysis but not by multivariate analysis (P = 0.053). Denosumab administration increases risk but not significantly (P = 0.053). Histone 3.3 G34W immunopositivity is not significant for predicting local recurrence.

Abstract
AIM Patients who undergo the Fontan procedure for complex congenital heart disease are prone to liver cirrhosis. Liver stiffness (LS) reflects liver fibrosis stage in patients with chronic viral hepatitis; however, its accuracy in predicting liver fibrosis stage in Fontan patients is controversial. We aimed to clarify the correlation between LS and liver fibrosis stage in Fontan patients. METHODS Fifty-eight Fontan patients were prospectively measured for LS with transient elastography. We undertook liver biopsy, cardiac catheterization, and laboratory tests in 22 of these patients (median age, 14.7 years; range, 9.9-32.1 years) with LS > 11.0 kPa (median, 19.2 kPa; range, 12.2-39.8 kPa); these elevated LS values suggest liver cirrhosis. RESULTS Histologically, all patients showed mild-to-severe portal and sinusoidal fibrosis but no cirrhosis. Statistically, LS did not predict histological liver fibrosis scores (p = 0.175). Liver stiffness was not correlated with central venous pressure (p = 0.456) or with the hepatic venous pressure gradient (HVPG; p = 0.062), although the p value for HVPG was only slightly above the threshold for significance. CONCLUSIONS Fontan patients are prone to developing both portal and sinusoidal fibrosis. Liver stiffness could be influenced by HVPG, and using the conventional cut-off values for LS overestimates and overtreats liver fibrosis in these patients.

Abstract
Bone marrow necrosis (BMN) is a rare but important complication of hematological malignancies. We report the case of a 52-year-old male patient with a recurrence of acute lymphoblastic leukemia (ALL) accompanied by BMN. After re-induction therapy, bone marrow aspiration (BMA) and biopsy from the iliac bone showed necrotic cells and eosinophilic debris, respectively. Magnetic resonance imaging (MRI) showed heterogeneous signals in the bilateral iliac bone, possibly reflecting various stages of BMN. BMA from the sternum eventually revealed the recurrence of ALL after a few weeks. Comprehensive assessments, including MRI and repeated bone marrow tests, are required when evaluating the underlying hematological malignancies of patients with BMN.

Abstract
Angiosarcoma is a malignant mesenchymal tumor characterized by the presence of vascular endothelial cells. Although rare, angiosarcoma developing in the mammary glands has a poor prognosis. We report a case of breast angiosarcoma with a preoperative diagnosis of late recurrence of breast cancer. A 78-year-old woman noticed a tumor in her right breast and visited our hospital. The patient had undergone breast-conserving surgery and axillary lymph node dissection from the right breast 12 years before the visit. The tumor was diagnosed as T4bN0M0, stage IIIB. Anastrozole was administered as postoperative adjuvant therapy for 5 years; the patient also received 50-Gy whole-breast radiation therapy after surgery. Physical examination during her visit revealed an elevated lesion with blue purpura around the nipple in the right breast. We performed breast ultrasound and detected a well-defined 19.6 × 16.4 × 10.7 mm hypoechoic tumor in the left subareolar area. The patient underwent core needle biopsy (CNB). Based on the CNB specimen findings, she was suspected to experience late local recurrence after surgery. Therefore, she underwent total mastectomy after breast-conserving surgery. A dark-red tumor sized 18 × 12 mm was found in a specimen from the nipple. The pathological diagnosis of the specimen revealed short spindle-shaped tumor cells with strong nuclear pleomorphism and a significant interstitial fibrosis. Immunohistochemistry using D2-40 and CD31 antibodies showed irregular luminal proliferation at the anastomosis, infiltration into the surrounding tissue, and massive necrosis, thereby leading to the diagnosis of breast angiosarcoma. We have reported a case of breast angiosarcoma with a preoperative diagnosis of late recurrence of breast cancer.

Abstract
Giant cell reparative granuloma (GCRG) is a benign nonneoplastic granulomatous lesion and is rare in the cranial bone. We present a pediatric case of this lesion arising from the condyle and lower clivus. A 9-year-old girl presented with slowly progressive hoarseness and dysphagia. She showed left glossopharyngeal, vagus, and hypoglossal nerve palsy. An osteolytic lesion around the lower clivus and condyle joint was accompanied by deformation of the craniovertebral junction. An endoscopic endonasal approach was used to decompress the cranial nerve and confirm the pathological finding. The lesion around the condyle was not resected to preserve occipito-cervical stability. The residual lesion has been observed carefully for 6 months, and regrowth has not occurred. GCRG is a rare granulomatous lesion in the cranial bone. This case is the first report of a pediatric clival GCRG. Treating pediatric GCRG may be helpful.

Abstract
Background Vascular invasion involving a tumor thrombus in the inferior vena cava and/or right atrium is an unfavorable prognostic factor after intrahepatic cholangiocarcinoma resection. We report an intrahepatic cholangiocarcinoma case with a tumor thrombus extending from the left hepatic vein via the inferior vena cava to the right atrium. Case presentation A 58-year-old man with epigastralgia was referred to our hospital after an emergent transcatheter arterial embolization was done following the radiological diagnosis of a ruptured hepatic tumor. The serum concentrations of carcinoembryonic antigen, carbohydrate 19-9, duke pancreatic monoclonal antigen type 2, and cytokeratin-19 fragments were elevated; meanwhile those of alfa-fetoprotein and des-γ-carboxy prothrombin were within normal ranges. A contrast-enhanced computed tomography scan showed a heterogeneously enhanced tumor, 13 cm in diameter, in the left lobe of the liver, enlarged lymph nodes along the lesser curvature of the stomach, and a tumor thrombus extending from the left hepatic vein via the inferior vena cava to the right atrium. We performed a left hemihepatectomy and tumor thrombectomy under total hepatic vascular exclusion to reduce the risk of sudden death. After dissection of the liver parenchyma along the left side of the middle hepatic vein, except for the left hepatic vein, the inferior vena cava just below the right atrium could be clamped by pulling down the left lobe of the liver toward the caudal side. The thrombus could be removed by incising the inferior vena cava under total hepatic vascular exclusion. Microscopic examination showed a tubular adenocarcinoma. Immunohistochemical staining was positive for cytokeratin-7, cytokeratin-19, and epithelial membrane antigen, but negative for arginase-1, glypican-3, and hepatocyte. The patient was pathologically diagnosed with an intrahepatic cholangiocarcinoma with a tumor thrombus in the inferior vena cava. Adjuvant chemotherapy with tegafur/gimeracil/oteracil was administered for 1 year. The patient remained in good health without cancer recurrence for over 4 years after the operation. Conclusion An aggressive surgical approach may be indicated for intrahepatic cholangiocarcinoma with a tumor thrombus in the inferior vena cava and/or right atrium to avoid the risk of impending death.

Abstract
OBJECTIVE Recent guidelines propose that both proton pump inhibitor (PPI) responders and nonresponders are included in eosinophilic esophagitis (EoE). Although multiple biopsies should be required to diagnose EoE because of patchy distribution of esophageal eosinophils, it is unclear whether multiple biopsies are required to evaluate histological effectiveness of PPI therapy. This study aimed to determine the optimal biopsy protocol after PPI therapy in patients with EoE. METHODS Of 110 EoE patients, 22 PPI nonresponders were enrolled. Intraepithelial eosinophils were counted in areas of high density in multiple biopsy specimens after PPI therapy. The prevalence of esophageal eosinophilia and peak eosinophil counts after PPI therapy was analyzed according to the biopsy sites and endoscopic findings. Positive predictive value (PPV) was calculated according to the number of biopsies. RESULTS Of 124 biopsies, 59 (47.6%) specimens showed esophageal eosinophilia (≥15 per high-power field). Eosinophil counts were significantly higher in specimens from the lower esophagus than in those from the upper esophagus but not in those from the middle esophagus. Prevalence of esophageal eosinophilia was 76.2, 40.9, and 24.3% in the lower, middle, and upper esophagus respectively. PPI nonresponders were diagnosed in all cases with 4 biopsy specimens obtained from the lower and middle esophagus, showing that PPV for non-effectiveness of PPI therapy was 0.910 (95% CI 0.773-1.000). The prevalence of esophageal eosinophilia and peak eosinophil counts was higher in cases with white plaques and linear furrows. CONCLUSION Multiple biopsies should be required to evaluate histological effectiveness of PPI therapy in patients with EoE. Four biopsies from the lower and middle esophagus may be sufficient.

Abstract
Pure mucinous breast carcinoma with micropapillary pattern (MUMPC) was proposed as a new histopathological variant of pure mucinous carcinoma (PMC) with tumor cells forming a micropapillary architecture. The Classification of Tumours of the Breast by the World Health Organization, however, does not differentiate MUMPC as a distinct subtype. There is currently no consensus whether tumors that exhibit these features are classified as PMC or invasive micropapillary carcinoma (IMPC) with associated mucin production. A 45-year-old woman was examined for a tumor in her left breast. Upon physical examination, an elastic hard mass of around 5 cm along with accompanying skin flare and ulceration was palpated in the upper outer quadrant of the left breast. Mammary ultrasonography revealed a clearly marginated hypoechoic tumor of 55.0 × 46.9 × 37.0 mm in size in the upper outer quadrant of the left breast. A vacuum-assisted biopsy (VAB) was performed in the same site and histopathological diagnosis of PMC was made. Contrast-enhanced magnetic resonance imaging (MRI) showed a T1W1 low-intensity signal and a T2W1 high-intensity signal at the primary focus, ring enhancement of the tumor margin, and stranding enhancement inside the tumor. A preoperative diagnosis of left breast cancer (PMC), cT4bN1M0, stage IIIB, luminal B-like was made. We performed a simple mastectomy with axillary lymph node dissection. A 55.0 × 48.1 × 37.1 mm tumor with the gelatinous cut surface was excised. Histopathological examination of the excised specimen revealed mucin lake formation in the tumor containing clusters of atypical cells. The atypical cells showed swollen, irregular nuclei and a papillary growth pattern that lead to the diagnosis of MUMPC.

Abstract
AIM To investigate clinicopathological significance of autophagy and its association with genetic alterations in gliomas. MATERIALS AND METHODS The expression of three autophagy-related proteins, light chain-3 (LC3), beclin 1, and p62 was immunohistochemically analyzed in 32 low-grade gliomas and 65 high-grade gliomas. RESULTS LC3, beclin 1, and p62 expression was positive in 70/94 (74%), 51/94 (54%) and 55/96 (57%) gliomas, respectively. High expression of LC3, beclin 1 and p62 was significantly more frequent in high-grade gliomas than in low-grade. Positive expression of LC3, beclin 1 and p62 were significantly positively correlated with overall survival, methylation of O6-methylyguanine-DNA methyltransferase (MGMT) promoter, mutations of isocitrate dehydrogenase 1 (IDH1) and telomerase reverse transcriptase (TERT) promoter, and 1p/19q co-deletion. Kaplan-Meier analyses revealed that LC3, p62 and autophagy status (positivity for at least two of the three proteins) were significantly associated with poorer survival. CONCLUSION Autophagy might be associated with the progression of glioma, particularly high-grade, and thus might be a useful prognostic factor in patients with glioma.

Abstract
Isolated sarcoma with features of mixed-phenotype acute leukemia (MPAL) is an extremely rare disease and it can be easily misdiagnosed as lymphoma or other malignancies. We herein report the case of a 61-year-old woman with non-leukemic sarcoma of the right pleura, pretracheal lymph node, and supraclavicular lymph node with features of MPAL, B/myeloid, not otherwise specified, which was first misdiagnosed as diffuse large B cell lymphoma. After performing a detailed re-examination of the biopsy specimens, few scattered eosinophilic myelocytes allowed us to reach a correct diagnosis of MPAL and the patient was thereafter successfully treated by intensified chemotherapy followed by cord blood transplantation.

Abstract
A 75-year-old man with stage IV lung adenocarcinoma was treated with osimertinib due to disease progression despite having been administered erlotinib. Both an epidermal growth factor receptor (EGFR) L858R mutation on exon 21 and a T790M mutation on exon 20 were detected in a specimen from a recurrent primary tumor. Five weeks after osimertinib initiation, he developed general fatigue and dyspnea. Chest computed tomography scan revealed diffuse ground glass opacities and consolidation on both lungs. An analysis of the bronchoalveolar lavage fluid revealed marked lymphocytosis, and a transbronchial lung biopsy specimen showed a thickened interstitium with fibrosis and prominent lymphocytic infiltration. We diagnosed the patient to have interstitial lung disease induced by osimertinib.

Abstract
Schwannoma arising from the olfactory system, often called olfactory groove schwannoma (OGS), is rare, as the olfactory bulb and tract, belonging to the central nervous system, should lack Schwann cells. Another rare entity called olfactory ensheathing cell tumor (OECT) has been reported, which mimics clinical and radiological characteristics of OGS. Here, we report two rare cases of schwannoma-like tumor in the anterior cranial fossa that showed negative staining for Leu7, but positive staining for Schwann/2E, and discuss their origin. Two cases of mass lesions in the anterior cranial fossa in a 26-year-old man and a 24-year-old woman were successfully removed. Morphological examination of these tumors was compatible with a diagnosis of schwannoma. Immunohistochemically, both cases were negative for Leu7, yielding a diagnosis of OECT, but were positive for the schwannoma-specific marker, Schwann/2E. Immunohistochemical staining results in our two cases question the current assumption that OGS and OECT can be distinguished only by Leu7 staining pattern. In conclusion, the origins of OGS and OECT remain to be determined, and further studies in larger numbers of cases are needed to characterize these rare tumors in the anterior cranial fossa.

Abstract
BACKGROUND Cholangiocarcinoma caused by exposure to 1,2-dichloropropane and/or dichloromethane is recognized as occupational cholangiocarcinoma. The aim of this study was to investigate the outcomes after resection of occupational cholangiocarcinoma to establish a treatment strategy for this disease. METHODS Clinicopathological findings and outcomes after surgical intervention in 20 patients with occupational cholangiocarcinoma were investigated. RESULTS Of 20 the patients, curative resection was performed in 16 patients. Three patients underwent radiation at the stump of the bile ducts. Adjuvant chemotherapy was performed in 12 patients. Biliary intraepithelial neoplasia, intraductal papillary neoplasm of the bile duct, and/or chronic bile duct injury was detected in most subjects. Intraabdominal infection developed after surgery in nine patients. Cholangiocarcinoma recurred in 12 of the 20 patients. The recurrent tumors in five patients developed at a different part of the bile duct from the primary tumor and a second resection was performed in four of these five patients. CONCLUSIONS The incidence of postoperative complications including intraabdominal infection was high in patients with occupational cholangiocarcinoma. Multicentric recurrence occurred not infrequently after surgery because the bile ducts had a high potential for the development of carcinoma. The aggressive treatment including second resection for the multicentric recurrence appeared to be effective.

Abstract
BACKGROUND The outcomes of hepatic resection in intrahepatic cholangiocarcinoma (ICC) patients with diabetes mellitus (DM), hypertension (HT), and dyslipidemia (DL) (metabolic components) remain unclear. METHODS The outcomes of 43 ICC patients without known risk factors for ICC who underwent hepatic resection were retrospectively reviewed. These patients were divided into three groups: those followed-up for metabolic components at least every 6 months (follow-up group, n=16), those not followed-up for metabolic components (no follow-up group, n=14), and those without metabolic components (control group, n=13). RESULTS In the follow-up group, 13 (81%) patients were further examined for ICC during follow-up because of abnormal screening results, such as elevated serum gamma-glutamyl transpeptidase and carbohydrate antigen 19-9 (CA19-9) concentrations or detection of hepatic tumor on ultrasonography and/or computed tomography, whereas most patients in the other two groups exhibited ICC-related symptoms. No patient in the follow-up group exhibited lymph node metastasis, whereas 43% of those in the no follow-up group and 46% in the control group had lymph node metastasis (p=0.005 and 0.004 vs. the follow-up group, respectively). All 16 patients in the follow-up group were diagnosed as International Union Against Cancer pathologic stage I or II (early stage). There were no significant differences in the incidence of postoperative recurrence between the three groups; however, the incidence of extrahepatic recurrence was lower in the follow-up group than in the no follow-up group and the control group (13% vs. 78% vs. 63%, p=0.0232). The 1-, 3-, and 5-year overall survivalrates in the follow-up group were better than those in the no follow-up and control groups (93/93/66% vs. 77/34/34% and 85/24/0%, p=0.034 and 0.001, respectively). CONCLUSIONS Routine measurement of serum gamma-glutamyl transpeptidase and/or CA19-9 levels and imaging examinations every 12 months (or 6 months, if possible) are recommended during follow-up for DM, HT, and DL to detect ICC at an early stage.

Abstract
BACKGROUND Advances in cancer immunotherapy in the pediatric field are needed in order to improve the prognosis of children with malignancies. We conducted a prospective phase I/II study of WT1 peptide vaccination for children with relapsed or refractory malignancies. METHODS The main eligibility criteria were affected tissues or leukemic cells expressing the WT1 gene, and patients (and donors for allogeneic hematopoietic stem cell transplantation) having HLA-A*24:02. Vaccination using the WT1 peptide (CYTWNQMNL), which was modified for higher affinity to this HLA-type molecule with the adjuvant Montanide ISA51, was performed weekly 12 times. RESULTS Twenty-six patients were enrolled and 13 (50.0%) completed the vaccination 12 times. Evidence for the induction of WT1-specific cytotoxic T-lymphocyte (CTL) responses without severe systemic side effects was obtained. Two out of 12 patients with bulky disease exhibited a transient clinical effect (one mixed response and one stable disease), three out of six patients with minimal residual disease achieved transient molecular remission, and five out of eight patients without a detectable level of the molecular marker, but with a high risk of relapse, had the best outcome of long-term continuous complete remission. CONCLUSIONS WT1 vaccination is a safe immunotherapy and induced WT1-specific CTL responses in children; however, as a single agent, vaccination only provided patients in remission, but with a high risk of relapse, with "long-term benefits" in the context of its use for relapse prevention. WT1 peptide-based treatments in combination with other modalities, such as anti-tumor drugs or immunomodulating agents, need to be planned.

Abstract
Background & Aims The utility of transient elastography (FibroScan) is well studied in adults but not in children. We sought to assess the feasibility of performing FibroScans and the characteristics of FibroScan-based liver profiles in Japanese obese and non-obese children. Methods FibroScan examinations were performed in pediatric patients (age, 1–18 yr) who visited Osaka City University Hospital. Liver steatosis measured by controlled attenuation parameter (CAP), and hepatic fibrosis evaluated as the liver stiffness measurement (LSM), were compared among obese subjects (BMI percentile ≥90%), non-obese healthy controls, and non-obese patients with liver disease. Results Among 214 children examined, FibroScans were performed successfully in 201 children (93.9%; median, 11.5 yr; range, 1.3–17.6 yr; 115 male). CAP values (mean±SD) were higher in the obese group (n = 52, 285±60 dB/m) compared with the liver disease (n = 40, 202±62, P<0.001) and the control (n = 107, 179±41, P<0.001) group. LSM values were significantly higher in the obese group (5.5±2.3 kPa) than in the control (3.9±0.9, P<0.001), but there were no significant differences in LSM between the liver disease group (5.4±4.2) and either the obese or control group. LSM was highly correlated with CAP in the obese group (ρ = 0.511) but not in the control (ρ = 0.129) or liver disease (ρ = 0.170) groups. Conclusions Childhood obesity carries a high risk of hepatic steatosis associated with increased liver stiffness. FibroScan methodology provides simultaneous determination of CAP and LSM, is feasible in children of any age, and is a non-invasive and effective screening method for hepatic steatosis and liver fibrosis in Japanese obese children.

Abstract
Embryonal tumor with abundant neuropil and true rosettes (ETANTR) is rarely seen in the brainstem, and there are few case reports of brainstem ETANTR in the literature. Accordingly, the characteristics and the role of surgical treatment of this rare entity remain unclear. The authors present a case of brainstem ETANTR involving a 33-month-old boy along with a review of the literature and discuss the role of surgical removal in the treatment of this entity. In the authors' case, the tumor was surgically treated with subtotal resection, which resulted in improvement of the patient's preoperative symptoms. Chemotherapy was initiated but did not appear to be effective, radiotherapy was declined, and the boy died 6 months after the operation. Based on their analysis of 10 previously reported cases and their own case, the authors conclude that, with respect to survival, surgery may be beneficial even in cases of ETANTR in the brainstem. They note, however, that further studies with a large number of cases are needed to validate the role of surgical treatment in brainstem ETANTR.

Abstract
BACKGROUND Cholangiocarcinoma has been reported in workers exposed to chlorinated organic solvents and has consequently been classified as an occupational disease (occupational cholangiocarcinoma) by the Japanese Ministry of Health, Labour and Welfare. This study aimed to identify the characteristics of nine workers newly diagnosed with occupational cholangiocarcinoma. METHODS This study was a retrospective study conducted in 13 hospitals and three universities. Clinicopathological findings of nine occupational cholangiocarcinoma patients from seven printing companies in Japan were investigated and compared with 17 cholangiocarcinoma patients clustered in a single printing company in Osaka. RESULTS Patient age at diagnosis was 31-57 years. Patients were exposed to 1,2-dichloropropane and/or dichloromethane. Serum γ-glutamyl transpeptidase activity was elevated in all patients. Regional dilatation of the intrahepatic bile ducts without tumor-induced obstruction was observed in two patients. Four patients developed intrahepatic cholangiocarcinoma and five developed hilar cholangiocarcinoma. Biliary intraepithelial neoplasia and/or intraductal papillary neoplasm of the bile duct was observed in four patients with available operative or autopsy specimens. CONCLUSIONS Most of these patients with occupational cholangiocarcinoma exhibited typical findings, including high serum γ-glutamyl transpeptidase activity, regional dilatation of the bile ducts, and precancerous lesions, similar to findings previously reported in 17 occupational cholangiocarcinoma patients in Osaka.

Abstract
BACKGROUND A nationwide survey on neonatal surgery conducted by the Japanese Society of Pediatric Surgeons has demonstrated that the mortality of neonatal intestinal perforation has risen over the past 15 years. The incidence of intestinal perforation in extremely low-birthweight (ELBW) neonates has been increasing as more ELBW neonates survive and as the live-birth rate of ELBW has increased. In contrast to necrotizing enterocolitis (NEC) and focal intestinal perforation (FIP), the pathogenesis of meconium-related ileus, defined as functional bowel obstruction characterized by delayed meconium excretion and microcolon, remains unclarified. METHODS The histology of 13 ELBW neonates with intestinal perforation secondary to meconium-related ileus was reviewed, and the radiology of 33 cases of meconium-related ileus diagnosed on contrast enema was reviewed. Specimens obtained from 16 ELBW neonates without gastrointestinal disease served as age-matched controls for histological assessment. RESULTS The size of the ganglion cell nucleus in meconium-related ileus and in control subjects was 47.3 ± 22.0 µm(2) and 37.8 ± 11.6 µm(2), respectively, which was not significantly different. In all cases of meconium-related ileus, contrast enema demonstrated a microcolon or small-sized colon, with a gradual caliber change in the ileum and filling defects due to meconium in the ileum or colon, showing not-identical locations of caliber changes and filling defects. CONCLUSION Morphological immaturity of ganglia was not suggested to be the pathogenesis of meconium-related ileus. Impaction of inspissated meconium is not the cause of obstruction, but the result of excessive water absorption in the hypoperistaltic bowel before birth, although the underlying mechanism responsible for the fetal hypoperistalsis remains unclear.

Abstract
A 3-year-old female presented with a large tumor occupying the right thoracic space. Open biopsy revealed the pathological diagnosis of pleuropulmonary blastoma. After the first-line chemotherapy, the patient underwent surgical resection, then two courses of high-dose chemotherapy. Three years later, follicular carcinoma of the right thyroid lobe was found, so a right hemithyroidectomy was performed. Five months later, the thyroid tumor recurred. The remaining thyroid lobe was completely excised and radioiodine therapy was administered. The patient has remained tumor-free for 3 years. The etiology and treatment of the uncommon combination of pleuropulmonary blastoma and thyroid carcinoma is discussed.

Abstract
Monitoring of posture change in sagittal plane and walking speed is important for evaluate the effectiveness of rehabilitation program or brace. We have developed a wearable device for monitoring human activity. However, in the previous system, there still remain several drawbacks for practical use such as accuracy in angle measurement, cumbersome cable arrangements, and so on. In order to improve these practical drawbacks, a new sensor system was designed, and its availability was evaluated. The results demonstrated that the accuracy of this system showed superior to that of the previous, and this system appears to be a significant means for quantitative assessment of the patient's motion.

Abstract
In Japan, mortality due to intestinal perforation has been increasing for the last 15 years, as the survival rate of extremely-low-birth-weight neonates (ELBWs) has been increasing. In our NICU, although the incidence of necrotizing enterocolitis has been decreasing, that of focal intestinal perforation (FIP) has been increasing. To elucidate the pathogenesis of FIP, a histological study was performed. For the last 20 years, in our NICU, 11 ELBWs with FIP, including one with multiple perforations and impending rupture, underwent laparotomy and enterostomy. The intestinal wall around the perforation was resected for histological study. Histological studies revealed well-developed ganglion cells in all the cases. Although some lymphocytic infiltration and hemorrhage were observed, no apparent neutrophilic infiltration, or necrotic change was identified in any case. No evidence of microcirculatory impairment was identified. The intestinal musculature discontinued abruptly with thinning in three cases, and without thinning in the others. The histology of impending rupture showed an absence of the muscularis with preservation of the remaining components of the bowel wall. The findings that the punched-out perforations had the appearance of Hirschsprung's disease, FIP exclusively occurred in ELBWs, and that neither mechanical obstruction nor necrotic change could be identified as the cause of the perforation suggest that immature bowel movement and congenital muscle defects may be involved in the pathogenesis of FIP.

Abstract
The importance of human posture monitoring is well recognized in the field of rehabilitation, in order to evaluate quantitatively the effectiveness of rehabilitation by a physical therapist. The activity monitoring is also well recognized as being useful in the field of certification of eligibility for long-term care. Assessment of the actual physical condition of the applicant tends to be difficult when determine the level of need for long-term care. Taking these circumstances in consideration, we attempted to measure the activities of patients in rehabilitation using a wearable device for monitoring human activity. The results clearly demonstrated that detailed motion characteristics could be detected during standing up, walking and sitting up as angle changes between specific body segments and as trunk motion acceleration.

Abstract
WT1 was first identified as a tumor suppressor involved in the development of Wilms' tumor. Recently, oncogenic properties of WT1 have been demonstrated in various hematological malignancies and solid tumors. Because WT1 has been identified as a molecular target for cancer immunotherapy, immunohistochemical detection of WT1 in tumor cells has become an essential part of routine practice. In the present study, the expression of WT1 was examined in 494 cases of human cancers, including tumors of the gastrointestinal and pancreatobiliary system, urinary tract, male and female genital organs, breast, lung, brain, skin, soft tissues and bone by immunohistochemistry using polyclonal (C-19) and monoclonal (6F-H2) antibodies against WT1 protein. Staining for C-19 and 6F-H2 was found in 35-100 and 5-88% of the cases of each kind of tumor, respectively. WT1-positive tumors included tumor of the stomach, prostate, and biliary and urinary systems, and malignant melanomas. A majority of the positive cases showed diffuse or granular staining in the cytoplasm, whereas ovarian tumors and desmoplastic small round cell tumors frequently showed nuclear staining. Glioblastomas, some of soft tissue sarcomas, osteosarcomas, and malignant melanomas of the skin showed extremely strong cytoplasmic staining as compared with other tumors. Western blot analysis showed that WT1 protein was predominantly expressed in the cytoplasm of the tumor cells in two cases of lung adenocarcinoma, supporting the intracytoplasmic staining for WT1 using immunohistochemistry. Immunohistochemical detection with routinely processed histologic sections could provide meaningful information on the expression of WT1 in cancer cells.

Abstract
We describe the clinical course and autopsy findings of a female fetus with hydrops fetalis due to a huge pericardial rhabdomyoma. Fetal echocardiography at 21 weeks gestation demonstrated a huge tumor in the left ventricle. The fetus died of hydrops fetalis due to cardiac dysfunction at 24 weeks gestation. Autopsy demonstrated that the tumor protruded from the epicardial region of the apex into the pericardial cavity and induced a hypoplastic left ventricle and lung. Microscopically, the cardiac tumor showed characteristics of rhabdomyoma. This localization of cardiac rhabdomyoma is rare, but we remain aware of the possibility of an unusual and rapid progression of cardiac rhabdomyoma.

Abstract
A comparative study of MRI and pathology was performed on a case of cryptococcal meningoencephalitis. An 11-year-old female presented with confusion and vomiting. On admission, CSF examination revealed spherical fungal cells with mild pleocytosis, decreased glucose and elevated protein level. MRI showed multiple punctate lesions in the basal ganglia with high intensity on T2-weighted image, while enhanced MRI revealed diffuse meningeal involvement. Post-mortem examination disclosed that the T2-weighted lesions found in the basal ganglia were aggregated small cystic lesions consisting of a cryptococcal invasion of Virchow-Robin spaces, termed "soap bubble lesions", characteristic findings of cryptococcal meningoencephalitis. Thus MRI findings of the basal ganglia and meninges may help to diagnose cryptococcal meningoencephalitis.
