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...

Anaplastic large T cell lymphoma (ALTCL) is rarely reported in domestic animals. Accordingly, the histopathological and immunohistochemical characteristics of ALTCL have not been well established in prairie dogs. The present report documents three cases in which prairie dogs were diagnosed with ALTCL arising in the subcutaneous tissue, oral mucosa or the mesenteric lymph nodes. Of the three cases, one was available for necropsy and the others were biopsy cases. Microscopically, moderate to large, pleomorphic neoplastic lymphocytes with ovoid to polygonal, bizarre-shaped nuclei, abundant cytoplasm and eosinophilic granules were seen in all cases...

Chronic expanding haematoma (CEH) is rare and refers to a gradually increasing haematoma that is not absorbed after surgery and trauma. This report highlights unusual mass occurring on the gluteus muscle, and the aim is to indicate the diagnostic method. It is necessary to consider the mechanism of the occurrence and to know the characters of CEH. The patient was a 51-year-old man who had noticed a soft mass on his right hip. The mass had gradually increased to 10 cm in size over the year. CT images revealed a haematoma...

BACKGROUND: Multinucleated Cell Angiohistiocytoma (MCAH) is a rare disease, first described by Smith and Wilson Jones in 1985. Since then, less than 100 cases have been reported in the literature. Clinically it is characterized by papules or plaques arising from a specific anatomical area such as lower extremities, dorsum of the hands and face. Some generalized cases have been reported. MAIN OBSERVATIONS: We report a case of 77-year-old woman who presented with multiple itching...

Proliferative fasciitis is a benign entity involving the subcutaneous tissues and fascias, characterized by the proliferation of fibroblast-like spindle cells and ganglion-like cells. However, proliferative fasciitis may be easily confused with sarcoma clinically and pathologically, because it appears as a rapidly growing painful mass and has histologic features such as high cellularity, bizarre morphologic patterns, mitotic figures, and diffuse infiltrative proliferation. Imaging findings of proliferative fasciitis have been very rarely reported...

A 94-year-old Korean woman was seen in the Emergency Department after a fall. CT examination of the maxillofacial region found multiple small linear metallic densities in the subcutaneous soft tissues of the face. The appearance of these densities was unchanged when compared to a study performed 2 years prior; however, the imaging interpretations of these densities were markedly different. Additional imaging during the course of her hospital stay demonstrated numerous similar densities in the breasts, abdomen, hips, and legs-finally diagnosed as "charm needles...

REVIEW
Sajid Bashir, Muhammad Shahbaz, Dilber Iqbal
We encountered a round artifact on images obtained with our SPECT/CT system: a small dark spot surrounded by a broad light ring. The artifact was due to a problem with the SPECT portion of the hybrid system and was successfully removed through servicing of the system. This case report describes this scanner-based artifact, which, to our knowledge, has not previously been reported in the literature.
