Leiomyoma with bizarre nuclei (LBN) have significant cytologic atypia, but high mitotic rate and tumor cell necrosis are absent. Although it is a benign leiomyoma variant, recurrent cases have been described. In this study, we investigated the clinical and pathologic features of LBN and compared them with related studies. A total of 30 patients diagnosed with LBN in our department were included in this study. In all cases, clinical data (age, complaint, surgery type), macroscopic features (size, location, number of leiomyomas, necrosis, and hemorrhage), microscopic features (bizarre cell distribution, bizarre cell density, cellularity, mitotic rate, tumor margin, necrosis, nuclear pseudoinclusions, karyorrhectic nuclei, prominent eosinophilic nucleoli with perinucleolar clearing, cytoplasmic eosinophilic inclusions, staghorn vessels, and alveolar-type edema), and follow-up data (recurrence and survival period) were evaluated...

An entity of bizarre plasma cells has been observed, containing spherical inclusions of immunoglobulins within the cytoplasm. These cells are termed as Mott cells and are believed to occur commonly in cases of chronic inflammation. Until now, they were reported to occur in systemic diseases, various hematolymphoid malignancies and in some syndromes; but their occurrence in chronic periapical infections of the oral cavity, given the paucity of available literature, raises questions about their obscure nature...

Sporadic Creutzfeldt-Jakob disease (sCJD) is a rare and fatal spongiform encephalopathy characterized by rapidly progressive dementia and myoclonus. The rarity of this disease and varied initial symptoms make the early diagnosis fairly challenging. Here, we present a case initially admitted for confusion and bizarre behaviors. She had acute deterioration of mental status, akinetic mutism, and myoclonus jerks four weeks later. Cerebrospinal fluid (CSF) analysis was positive for protein 14-3-3. Brain magnetic resonance imaging (MRI) showed hyperintensities in the bilateral cortex, basal ganglia, and thalami in diffusion-weighted imaging (DWI)...

PURPOSE: The aim of this paper is to investigate the association between suicide and Lyme and associated diseases (LAD). No journal article has previously performed a comprehensive assessment of this subject. INTRODUCTION: Multiple case reports and other references demonstrate a causal association between suicidal risk and LAD. Suicide risk is greater in outdoor workers and veterans, both with greater LAD exposure. Multiple studies demonstrate many infections and the associated proinflammatory cytokines, inflammatory-mediated metabolic changes, and quinolinic acid and glutamate changes alter neural circuits which increase suicidality...

Colin J R Stewart
Cervical high-grade squamous intraepithelial lesions (HSILs) are typically characterised by a proliferation of immature basaloid cells with relatively uniform hyperchromatic nuclei. In this report we describe 19 cases of HSIL exhibiting focal but very marked nuclear atypia often associated with multinucleation ('pleomorphic HSIL'). The bizarre cytological changes mainly involved the basal epithelium particularly in endocervical crypts where the neoplastic cells undermined the native glandular epithelial cells...

Leiomyomas associated with hereditary leiomyomatosis and renal cell carcinoma syndrome and leiomyomas with bizarre nuclei often show overlapping morphological features, in particular cells with prominent eosinophilic nucleoli, perinucleolar halos, and eosinophilic cytoplasmic inclusions. Although hereditary leiomyomatosis and renal cell carcinoma syndrome is defined by fumarate hydratase (FH) germline mutations, resulting in S-(2-succino)-cysteine (2SC) formation, it is unknown whether leiomyomas with bizarre nuclei show similar alterations...

Ouranosaurus nigeriensis is an iconic African dinosaur taxon that has been described on the basis of two nearly complete skeletons from the Lower Cretaceous Gadoufaoua locality of the Ténéré desert in Niger. The entire holotype and a few bones attributed to the paratype formed the basis of the original description by Taquet (1976). A mounted skeleton that appears to correspond to O. nigeriensis has been on public display since 1975, exhibited at the Natural History Museum of Venice. It was never explicitly reported whether the Venice specimen represents a paratype and therefore, the second nearly complete skeleton reported in literature or a third unreported skeleton...

While investigating social cognitive impairments in schizophrenia, prominent evidence has been found that patients with schizophrenia show a tendency to misclassify neutral stimuli as negatively valenced. Within this population, patients presenting delusions are more prone to this phenomenon. In a previous study, Schizophrenia spectrum (SzSp) patients rated positive, negative and neutral stimuli that were multimodally presented, while assessed with a checklist exploring anomalous subjective experiences and evaluated for positive and negative symptomatology...

A male patient with obstructive jaundice was found to have an incidental nodule within the inferior vena cava (IVC), below the level of the renal vein, on abdominal imaging. At the time of the Whipple's procedure for pancreatic adenocarcinoma, the IVC mass measuring 3.4×2.7×2.2 cm was also removed. Histologically, the lesion was well circumscribed, composed focally of spindle-shaped cells with cigar-shaped nuclei reminiscent of smooth muscle and a dominant pervasive, pleomorphic, bizarre giant cell component...

AIMS: Uterine leiomyosarcomas frequently show p16 immunoexpression. However, p16 may also be expressed in some benign leiomyoma variants such as leiomyomas with bizarre nuclei and cellular leiomyomas, limiting its utility as a biomarker to distinguish between benign and malignant neoplasms. We investigated p16 expression in leiomyomas with infarct-type necrosis, tumours which may sometimes be misinterpreted as smooth muscle tumors of uncertain malignant potential or even leiomyosarcoma on conventional light microscopy...

Somatoparaphrenia (SP) typically occurs after a right-hemisphere stroke, where the patient refers to his/her hemiplegic left hand as belonging to someone else. In this report, we review the literature for the brain structures affected in SP. We also report three cases with varying degrees of SP: a typical case, one case where SP affected the visceral sensations, and one case where a concurring psychiatric condition lead to a very complex, bizarre delusion.

Bell-shaped ciliates of the subclass Peritrichia, such as Vorticella, Carchesium and Epistylis, are commonly found in freshwater and other aquatic environments, either solitary or colonial. Peritrichs attach to a substratum via a contractile or non-motile stalk, and collect food particles by water current using ciliary rows around the edge of the bell, called the peristome. Some peritrichs are epibiotic and ectocommensalistic associates of aquatic insects and other animals, settling on the surface of their specific hosts...

Korsakoff syndrome is a chronic memory disorder caused by a severe deficiency of thiamine that is most commonly observed in alcoholics. However, some have proposed that focal structural lesions disrupting memory circuits-in particular, the mammillary bodies, the mammillothalamic tract, and the anterior thalamus-can give rise to this amnestic syndrome. Here, the authors present 4 patients with reversible Korsakoff syndromes caused by suprasellar retrochiasmatic lesions compressing the mammillary bodies and adjacent caudal hypothalamic structures...

AIM: Recent studies have highlighted that attenuated psychotic symptoms (APS) are an important source of distress in ultra high risk (UHR) individuals and that this distress is related to transition to psychosis (TTP). This study examined distress associated with APS in UHR individuals and investigated its association with TTP. METHODS: The Comprehensive Assessment of At-Risk Mental State (CAARMS) was used to identify 173 UHR individuals, who were included as participants in the study...

The differences in molecular mechanisms between osteochondroma and bizarre parosteal osteochondromatous proliferation (BPOP) remain to be fully elucidated. In the present study, the differentially expressed genes between BPOP and osteochondroma were obtained from the Gene Expression Omnibus online database, and the associations among these genes were analyzed using the Database for Annotation, Visualization, and Integrated Discovery (DAVID) online bioinformatics software. The results revealed several differentially expressed genes between human BPOP and osteochondroma...

Schizophrenia is often associated with disrupted brain connectivity. However, identifying specific neuroimaging-based patterns pathognomonic for schizophrenia and related symptom severity remains a challenging open problem requiring large-scale data-driven analyses emphasizing not only statistical significance but also stability across multiple datasets, contexts and cohorts. Accurate prediction on previously unseen subjects, or generalization, is also essential for any useful biomarker of schizophrenia. In order to build a predictive model based on functional network feature patterns, we studied whole-brain fMRI functional networks, both at the voxel level and lower-resolution supervoxel level...

Posttransplant lymphoproliferative disorders (PTLDs) are a diverse group of lymphoid or plasmacytic proliferations frequently driven by Epstein-Barr virus (EBV). EBV-negative PTLDs appear to represent a distinct entity. This report describes an unusual case of a 33-year-old woman that developed a monomorphic EBV-negative PTLD consistent with diffuse large B-cell lymphoma (DLBCL) 13 years after heart-lung transplant. Histological examination revealed marked pleomorphism of the malignant cells including nodular areas reminiscent of classical Hodgkin lymphoma (cHL) with abundant large, bizarre Hodgkin-like cells...
