Abstract
We herein present a fatal case of constrictive pericarditis (CP) due to acute myelomonocytic leukemia (AMML) in a patient who initially complained of an acute onset of chest pain two days after COVID-19 vaccination. An autopsy revealed pericardial infiltration of leukemic cells. CP is rarely associated with leukemia and only 14 cases have been reported in the literature. The etiology of CP in previous reports included leukemic infiltration, graft-versus-host disease, drug-induced, post-radiation, autoimmune, and otherwise unidentified. This case indicates that leukemic infiltration can cause CP and that clinicians should include leukemia in the differential diagnosis of CP.

Abstract
Uterine tumor resembling ovarian sex cord tumor (UTROSCT) is a rare tumor with low malignant potential that commonly occurs in middle age. Although more than 100 cases have been reported to date, myxoid morphology is not well documented. Here, we present a 75-yr-old woman with abnormal vaginal bleeding, with an 8-cm mass in the uterine corpus detected by irregular, high-intensity signaling on T2-weighted imaging. The uterine mass had a glistening mucinous appearance on gross examination. Microscopically, most of the tumor cells were floating in the myxoid stroma. The tumor cells formed clusters or nests with abundant cytoplasm, while some exhibited trabecular or rhabdoid appearances. Immunohistochemically, tumor cells were positive for pancytokeratin (AE1/AE3), α-smooth muscle actin, CD10, progesterone receptor, and some sex cord markers such as calretinin, inhibin, CD56, steroidogenic factor-1. Electron microscopy demonstrated epithelial and sex cord differentiation. This tumor was negative for JAZF1-JJAZ1 fusion gene that is frequently found in low-grade endometrial stromal sarcoma. Fusion genes related to UTROSCT, including NCOA2/3 , were not detected by reverse transcription polymerase chain reaction. The present case suggests that UTROSCT should be included in the differential diagnosis of myxoid uterine tumors.

Abstract
BACKGROUND Recently, various types of engineered autologous chondrocyte implantation (ACI) have been developed. Atelocollagen-associated ACI (A-ACI) is the only ACI procedure covered by Japanese Health Insurance since 2013. The indications of the A-ACI are traumatic cartilage defects and osteochondral dissecans (OCD) for knee joints. PURPOSE To evaluate midterm clinical results after A-ACI for the treatment for full-thickness cartilage defects of the knee. METHODS Thirteen consecutive patients who underwent A-ACI between 2014 and 2018 had been prospectively enrolled in this study. There were 11 men and 2 women with a mean age of 34 years at the time of surgery. The causes of the cartilage defect were trauma in 10 knees and OCD in 3 knees. The total number of lesions was 15, which were comprised of the medial femoral condyle in 5 knees, the lateral femoral condyle in 5 knees, and the femoral trochlea in 5 knees. The mean size of the lesion was 5.3 cm2. Each knee was clinically and radiologically evaluated preoperatively and postoperatively. RESULTS The mean Lysholm score improved significantly from 74.0 points to 94.0 points (p = 0.008) and each subscale in Knee injury and Osteoarthritis Outcome Score improved significantly (p < 0.001) at the mean final follow-up period of 51 months (range, 36-84 months). The magnetic resonance observation of cartilage repair tissue 2.0 score at the mean follow-up of 38 months was significantly higher than that at 2 months postoperatively (p = 0.014). According to the International Cartilage Repair Society (ICRS) grading scale, 3 knees were graded as normal, 3 knees as nearly normal, and 1 knee as severely abnormal in second-look arthroscopic evaluation at a mean of 22 months (range, 8-41 months) after A-ACI. CONCLUSION The present study showed a significant subjective and objective clinical improvement in the A-ACI for large cartilage defects of the knee at a mean follow-up of 51 months (range, 36-84 months).

Abstract
BACKGROUND Unlike the already established effect of Helicobacter pylori (H. pylori) eradication on gastric mucosa-associated lymphoid tissue (MALT) lymphoma, its therapeutic effect on primary gastric diffuse large B-cell lymphoma (DLBCL) is still unclear. AIM To clarify the efficacy of H. pylori eradication treatment for primary gastric DLBCL. METHODS We reported on 3 new cases, and added them to 3 previously reported cases. We analyzed the usefulness of H. pylori eradication treatment for gastric DLBCL for a total of 6 cases at our center. RESULTS Of the 6 patients (27-90 years old, 3 males and 3 females), all 3 patients with single lesions (one transformed from MALT lymphoma) achieved complete remission (CR) after H. pylori eradication. Regarding the 2 newly reported cases, CR was maintained for more than 6 years with eradication treatment alone. In contrast, none of the 3 patients with 2 lesions achieved CR. In 1 newly reported case, endoscopic CR was achieved in one lesion, while stable disease was obtained in the other lesion. Two patients with progressive disease responded to standard chemotherapy ± radiation and remained in CR for more than 6 years. CONCLUSION We believe it is worthwhile to attempt H. pylori eradication for elderly patients with primary gastric DLBCL in a single lesion with a small tumor burden.

Abstract
Neural regeneration is extremely difficult to achieve. In traumatic brain injuries, the loss of brain parenchyma volume hinders neural regeneration. In this study, neuronal tissue engineering was performed by using electrically charged hydrogels composed of cationic and anionic monomers in a 1:1 ratio (C1A1 hydrogel), which served as an effective scaffold for the attachment of neural stem cells (NSCs). In the 3D environment of porous C1A1 hydrogels engineered by the cryogelation technique, NSCs differentiated into neuroglial cells. The C1A1 porous hydrogel was implanted into brain defects in a mouse traumatic damage model. The VEGF-immersed C1A1 porous hydrogel promoted host-derived vascular network formation together with the infiltration of macrophages/microglia and astrocytes into the gel. Furthermore, the stepwise transplantation of GFP-labeled NSCs supported differentiation towards glial and neuronal cells. Therefore, this two-step method for neural regeneration may become a new approach for therapeutic brain tissue reconstruction after brain damage in the future.

Abstract
Krabbe disease is a lysosomal storage disease caused by a deficiency of the galactocerebrosidase (GALC) enzyme, which leads to demyelination of the central and peripheral nervous systems. Almost all patients with Krabbe disease are infants, and this is the first report of adult-onset cases that describe pathological findings. Here, we present two autopsy cases: a 73-year-old female and a 2-year-old male. The adult-onset case developed symptoms in her late thirties and was diagnosed by the identification of GALC D528N and L634S mutations and by T2-weighted magnetic resonance imaging; she had increased signal in the white matter along the pyramidal tract to the bilateral precentral gyrus, as well as from the triangular part to the posterior horn of the lateral ventricle. Microscopically, Klüver-Barrera staining was pale in the white matter of the precentral gyrus and occipito-thalamic radiation, and a few globoid cells were observed. The GALC mutations that were identified in the present adult-onset case do not completely inactivate GALC enzyme activity, resulting in focal demyelination of the brain.

Abstract
Colorectal follicular lymphoma (FL) is rare. In addition, it is even rarer that colon cancer develops synchronously with colorectal lymphoma. The present study reports a case of sigmoid colon cancer that developed 6 months after endoscopic resection of rectal FL. A 71-year-old man with a history of developing mucosa-associated lymphoid tissue lymphoma in his stomach at age 48, right neck region at age 59 (the latter later modified as FL) and lung adenocarcinoma at age 60 now suffers from rectal FL. Endoscopic submucosal dissection (ESD) was performed at our hospital (Aiiku Hospital), and 6 months after the treatment, sigmoid colon cancer was confirmed by colonoscopy for the follow-up study. The patient was successfully curatively resected by ESD plus local resection and has survived without a recurrence for >3 years with no treatment. It was speculated that in the present case, cancer-related genes were changed as a carcinogenic mechanism due to decreased immune function associated with the onset of lymphoma.

Abstract
Accumulation of phosphorylated α-synuclein in the central and peripheral nervous systems is a histological hallmark of Lewy body disease (LBD), including Parkinson's disease (PD), dementia with Lewy bodies (DLB), and LB-related pure autonomic failure. The submandibular gland is employed as a biopsy site for detecting Lewy pathology; however, the incidence of Lewy pathology in this region in autopsy-proven LBD cases at all stages from an aged Japanese cohort remains unclear. To validate the utility of Lewy pathology of the submandibular gland as a diagnostic biomarker for LBD, we investigated the submandibular gland Lewy pathology in autopsied patients. To determine the specificity, we prospectively evaluated the submandibular gland in 64 consecutive autopsied patients. To determine the sensitivity, we retrospectively assessed the submandibular gland in 168 consecutive autopsied patients who had prodromal or clinical LBD. In the prospective study, Lewy pathology was found in 21 of 64 patients, and nine of those 21 patients had the submandibular gland Lewy pathology. No Lewy pathology was found in 43 patients without CNS Lewy pathology, giving a specificity of 100%. In the retrospective study, Lewy pathology of the submandibular gland was detected in 126 of 168 patients. The sensitivity was 89.1% in PD and 75.4% in DLB. The sensitivity increased with disease progression. These findings support the utility of the submandibular gland biopsy for the pathological diagnosis of LBD.

Abstract
BACKGROUND This study aimed to investigate the frequency and risk factors for cerebral artery stenosis and occlusion in patients with polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes (POEMS) syndrome. METHODS We reviewed results of magnetic resonance angiography (MRA) or computed tomography angiography (CTA) in 61 patients with POEMS syndrome seen between 2010 and 2017. Stenosis or occlusion was assessed in the initial MRA/CTA. Multivariate analysis was used to identify risk factors for artery stenosis/occlusion. In an autopsy case, pathologic examination was conducted of the occluded middle cerebral arteries. RESULTS Stenosis (> 50 %) or occlusion of the major cerebral arteries was found in 29 (47.5 %) patients on the initial MRA/CTA. The internal carotid artery was involved most frequently (32.8 %), followed by the anterior (21.3 %) and middle (16.4 %) cerebral arteries. The basilar (1.3 %) and vertebral (3.6 %) arteries were rarely affected. Cerebral infarction developed in eight (13.1 %) patients. The serum vascular endothelial growth factor (VEGF) level was an independent predictor for stenosis/occlusion (odds ratio, 1.228; 95 % confidence interval, 1.042-1.447; P = 0.014). An autopsy study showed occluded middle cerebral arteries by fibrous and myxomatous thickening of intima with splitting of the internal elastic lamina. Follow-up MRA in 23 patients showed improved, worsened, and unchanged stenosis in 20.7 %, 8.7 %, and 69.6 %, respectively. CONCLUSIONS Cerebral large-vessel stenosis or occlusion is frequently seen in approximately half of patients with POEMS syndrome. Vasculopathy was related to serum VEGF levels and thereby disease activity. Assessment of cerebral vessels is recommended in these patients to improve management.

Abstract
Here we present the case of a 73-year-old male with rectal adenocarcinoma with heterotopic ossification (HO). Cancer-associated HO in the digestive system is rare. Thus, the precise mechanism and clinicopathological significance of HO have not yet been defined. To clarify the molecular mechanisms of HO, we analyzed the expression levels of signaling molecules related to epithelial-mesenchymal transition (EMT) that lead to ossification in the tumor cells discriminating the ossified area (HO-area) and non-ossified area (non-HO area). Expression levels of BMP4 were elevated in both areas, whereas BMP2 was specifically increased in the HO-area by qPCR. EMT-related molecules such as Snail and Slug were especially higher in the HO-area. By immunohistochemistry, the expression of Smad4, nuclear staining of β-catenin, and the phosphorylated form of GSK-3β were detectable in both areas, and GSK-3β was highly phosphorylated in the HO-area. The tumor growth rate was extremely high, with the Ki-67 labeling index at 90%. In the HO-area, osteoblasts with alkaline phosphatase expression were distributed surrounding the tumor cells. This is the first demonstration of the involvement of EMT in HO of colon cancer through BMP/SMAD and WNT/β-catenin signaling pathways, which are especially prominent in the HO-area leading to the osteogenic property.

Abstract
Anorexia nervosa (AN) is a serious eating disorder characterized by self-starvation and extreme weight loss. It has the highest mortality rate among all psychiatric disorders. Recent research indicates that malnutrition in AN patients induces various kinds of functional brain damage, but the pathophysiology of AN remains unclear. We report here the neuropathological findings of a 31-year-old Japanese woman. At age 24, she had a fear of gaining weight and reduced her dietary intake; she had extremely low body weight associated with overeating then self-induced vomiting. She was clinically diagnosed as having AN and was admitted to a psychiatric hospital with severe depression and suicidal thoughts. At age 31, she died despite intensive physical care and psychotherapy. Neuropathological examination revealed increased capillary blood vessels and slight fibrillary gliosis in the mammillary bodies, with similarities to Wernicke encephalopathy. The brainstem exhibited the characteristic features of central pontine myelinolysis, characterized by a sharply demarcated region of myelin pallor and relative sparing of axons. Senile changes, including neurofibrillary tangles/senile plaques, were not significant. Severe fibrillary gliosis was prominent around periventricular regions, including the caudate nucleus and nucleus accumbens, which are associated with cognition, emotion, and emotional behaviors via the dopaminergic pathways. These findings indicate that prolonged malnutrition in AN patients may induce brain damage, leading to dysfunction of the reward-related dopaminergic pathways. Furthermore, they represent the first pathological evidence that dysfunction of the cortico-limbic-striatal circuitry is involved in the pathophysiology of psychiatric symptoms in AN patients.

Abstract
Cell adhesion molecule 1 (CADM1), which mediates intercellular adhesion between epithelial cells, is shown to be highly expressed in small-cell lung cancer (SCLC) and to enhance tumorigenicity of SCLC cells in nude mice. Here, we investigated the molecular mechanism underlying the oncogenic role of CADM1 in SCLC. CADM1 promoted colony formation of SCLC cells in soft agar. Analysis of deletion and point mutants of the conserved protein-binding motifs in CADM1 revealed that the 4.1 protein-binding motif in the cytoplasmic domain is responsible for the promotion of colony formation. Among the actin-binding 4.1 proteins, 4.1R was the only protein whose localization to the plasma membrane is dependent on CADM1 expression in SCLC cells. Knockdown of 4.1R suppressed the colony formation enhanced by CADM1, suggesting that 4.1R is required for the oncogenic role of CADM1 in SCLC. In primary SCLC, CADM1 expression was correlated with membranous localization of 4.1R, as was observed in a SCLC cell line. Moreover, membranous co-localization of CADM1 and 4.1R was associated with more advanced tumor stage. These results suggest that the formation of CADM1-4.1R complex would promote malignant features of SCLC.

Abstract
Lewy body disease (LBD) is a spectrum of progressive neurodegenerative disorders characterized by the wide distribution of Lewy bodies and neurites in the central and peripheral nervous system (CNS, PNS). Clinical diagnoses include Parkinson's disease (PD), dementia with Lewy bodies, or pure autonomic failure. All types of LBD are accompanied by non-motor symptoms (NMSs) including gastrointestinal dysfunctions such as constipation. Its relationship to Lewy body-related α-synucleinopathy (Lewy pathology) of the enteric nervous system (ENS) is attracting attention because it can precede the motor symptoms. To clarify the role of ENS Lewy pathology in disease progression, we performed a clinicopathological study using the Brain Bank for Aging Research in Japan. Five-hundred and eighteen cases were enrolled in the study. Lewy pathology of the CNS and PNS, including the lower esophagus as a representative of the ENS, was examined via autopsy findings. Results showed that one-third of older people (178 cases, 34%) exhibited Lewy pathology, of which 78 cases (43.8%) exhibited the pathology in the esophagus. In the esophageal wall, Auerbach's plexus (41.6%) was most susceptible to the pathology, followed by the adventitia (33.1%) and Meissner's plexus (14.6%). Lewy pathology of the esophagus was significantly associated with autonomic failures such as constipation (p < 0.0001) and among PNS regions, correlated the most with LBD progression (r = 0.95, p < 0.05). These findings suggest that the propagation of esophageal Lewy pathology is a predictive factor of LBD.

Abstract
Dentatorubral-pallidoluysian atrophy (DRPLA) is an autosomal dominant neurodegenerative disorder caused by a CAG nucleotide repeat expansion in atrophin 1. A previous report described cerebellar white matter lesions on magnetic resonance imaging (MRI) in elderly-onset DRPLA patients, but this finding has not been fully investigated in a total population of DRPLA patients, including juvenile or early-adult onset patients. Herein, we attempted to determine the frequency, distribution pattern, and features of the cerebellar white matter lesions in 30 consecutive DRPLA patients. We also assessed the relationships between the cerebellar white matter lesions and clinical parameters and other MRI findings. The cerebellar white matter lesions were found in 43% of the 30 DRPLA patients, and in 70% of the late adult-onset DRPLA patients. In approx. Two-thirds of the patients with cerebellar white matter lesions, the lesions were localized in the paravermal area (paravermal lesions). Multiple logistic regression analyses revealed that the Fazekas grade of 'cerebral' white matter lesions was independently associated with 'cerebellar' white matter lesions. In conclusion, cerebellar white matter lesions are one of the distinctive MRI features in DRPLA patients, especially in patients with older age at onset. Cerebellar white matter lesions, as well as cerebral white matter lesions, might originate from the disease process of DRPLA itself, and they often have a characteristic distribution of paravermal lesions.

Abstract
AIM Tongue bites frequently occur during seizures in epilepsy patients. We report two cases of cognitively impaired Lennox-Gastaut syndrome patients with reactive lesions on the tongues. CASE PRESENTATIONS Case 1 was a 30-year-old man whose chief complaint was mouth pain. Local finding was a small bean-sized pedunculated mass on the tongue, histopathologically diagnosed as inflammatory fibrous hyperplasia. Case 2 was a 45-year-old man whose chief complaint was bleeding from the mouth. His clinical finding was blood loss anemia. Local finding was a 20-mm-diameter pedunculated mass on the tongue, histopathologically diagnosed as pyogenic granuloma. CONCLUSION These mass lesions were believed to be reactive, caused by repetitive minor damage involving reparative fibrous tissue response. Therefore, the two cases may have involved reparative responses to mucosal injury incurred by accidental bites during epileptic seizures. Intellectual disability made medical treatment difficult and had allowed the massive lesions to form. It is necessary for cognitively impaired epilepsy patients to undergo regular dental examinations in order to get used to dental checks and to increase the number of intraoral observations in the context of close cooperation between dentists and epilepsy therapists.

Abstract
YAP1, the main Hippo pathway effector, is a potent oncogene and is overexpressed in non‐small‐cell lung cancer (NSCLC); however, the YAP1 expression pattern in small‐cell lung cancer (SCLC) has not yet been elucidated in detail. We report that the loss of YAP1 is a special feature of high‐grade neuroendocrine lung tumors. A hierarchical cluster analysis of 15 high‐grade neuroendocrine tumor cell lines containing 14 SCLC cell lines that depended on the genes of Hippo pathway molecules and neuroendocrine markers clearly classified these lines into two groups: the YAP1‐negative and neuroendocrine marker‐positive group (n = 11), and the YAP1‐positive and neuroendocrine marker‐negative group (n = 4). Among the 41 NSCLC cell lines examined, the loss of YAP1 was only observed in one cell line showing the strong expression of neuroendocrine markers. Immunostaining for YAP1, using the sections of 189 NSCLC, 41 SCLC, and 30 large cell neuroendocrine carcinoma (LCNEC) cases, revealed that the loss of YAP1 was common in SCLC (40/41, 98%) and LCNEC (18/30, 60%), but was rare in NSCLC (6/189, 3%). Among the SCLC and LCNEC cases tested, the loss of YAP1 correlated with the expression of neuroendocrine markers, and a survival analysis revealed that YAP1‐negative cases were more chemosensitive than YAP1‐positive cases. Chemosensitivity test for cisplatin using YAP1‐positive/YAP1‐negative SCLC cell lines also showed compatible results. YAP1‐sh‐mediated knockdown induced the neuroendocrine marker RAB3a, which suggested the possible involvement of YAP1 in the regulation of neuroendocrine differentiation. Thus, we showed that the loss of YAP1 has potential as a clinical marker for predicting neuroendocrine features and chemosensitivity.
