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...

A rounded artifact was encountered on our GE Infinial Hawkeys SPECT/CT system. The artifact was due to a problem in SPECT part of the hybrid system. The small dark part is surrounded by the large white concentric ring. We described this scanner based artifact in this case report and was not pointed out in the literature before by researchers. The artifact was removed after necessary service.

RATIONALE: Accumulating evidence indicates that the mixed serotonin and dopamine receptor agonist lysergic acid diethylamide (LSD) induces an altered state of consciousness that resembles dreaming. OBJECTIVES: This study aimed to test the hypotheses that LSD produces dreamlike waking imagery and that this imagery depends on 5-HT2A receptor activation and is related to subjective drug effects. METHODS: Twenty-five healthy subjects performed an audiorecorded guided mental imagery task 7 h after drug administration during three drug conditions: placebo, LSD (100 mcg orally) and LSD together with the 5-HT2A receptor antagonist ketanserin (40 mg orally)...

Although the International Affective Picture System (IAPS) is used to evaluate emotions (valence, arousal, and dominance evoked by a large set of photographs), bizarre images in works of art have not been assessed with the IAPS procedures. Understood here as strange, non-sense, and absurd mental contents or expressions accompanied by surprise and confusion emotions, bizarreness was assessed after healthy adult volunteers assigned this specified variable to 140 Grete Stern's photomontages overtly intended to illustrate strange, absurd, and non-sensical contents in dream reports...

A comprehensive understanding of psychosis requires models that link multiple levels of explanation: the neurobiological, the cognitive, the subjective, and the social. Until we can bridge several explanatory gaps, it is difficult to explain how neurobiological perturbations can manifest in bizarre beliefs or hallucinations, nor how trauma or social adversity can perturb lower-level brain processes. We propose that the predictive processing framework has much to offer in this respect.Weshow how this framework may underpin and complement source monitoring theories of delusions and hallucinations and how, when considered in terms of a dynamic and hierarchical system, it may provide a compelling model of several key clinical features of psychosis...

Monolayer hexagonal boron nitride (h-BN) possesses a wide bandgap of ~6 eV. Trimming down the bandgap is technically attractive, yet poses remarkable challenges in chemistry. One strategy is to topological reform the h-BN's hexagonal structure, which involves defects or grain boundaries (GBs) engineering in the basal plane. The other way is to invite foreign atoms, such as carbon, to forge bizarre hybrid structures like hetero-junctions or semiconducting h-BNC materials. Here we successfully developed a general chemical method to synthesize these different h-BN derivatives, showcasing how the chemical structure can be manipulated with or without a graphene precursor, and the bandgap be tuned to ~2 eV, only one third of the pristine one's...

BACKGROUND: Combined small cell lung carcinoma (SCLC) is defined as SCLC combined with elements of non-small cell lung carcinoma (NSCLC), accounting for approximately 30% of cases of SCLC. However, combined SCLC and giant cell carcinoma (GC) is very rare. CASE PRESENTATION: A 50-year-old woman with a 45 pack-year smoking history was referred to our hospital for further investigation of an abnormal left hilar shadow. Chest computed tomography (CT) revealed a 28-mm solid pulmonary nodule in the left lower lobe and an enlarged left hilar lymph node adjacent to the left main pulmonary artery...

Schizotypal personality disorder (SPD) is characterised by thought disorders, experiences of illusions, obsessive ruminations, bizarre or eccentric behaviour, cognitive problems and deficits in social functioning - symptoms that SPD shares with schizophrenia. Efforts have been undertaken to investigate the relationship between these conditions regarding genetics, pathophysiology, and phenomenology. However, treatment of SPD with antipsychotics has received less scientific attention. Embase and PubMed databases were searched using all known generic names of antipsychotics as search terms in combination with the following diagnostic terms: latent schizophrenia, schizotypal disorder, latent type schizophrenia, or SPD...

Disorders of skin or its appendages may be the tell-tale signs of an underlying disease. Over the last one year we had a series of patients attending the dermatology outpatient services at our institute for bizarre nail changes. Evaluation of these patients led us to diagnose chronic selenium toxicity. This article is protected by copyright. All rights reserved.

Liquid foreign material injection has been used as an early medical intervention since the end of nineteenth century for the augmentation of body shape. Nowadays, these types of procedures have been abandoned by health professionals due to late onset of serious complications. However, it is still misused by some subcultures such as bodybuilders, passive homosexuals, transsexuals, and patients with mental illness. This article discusses a male patient who injected himself with a large amount of sunflower oil, which became complicated by an inflammatory response-abscess formation and sclerosing lipogranuloma of breasts...

BACKGROUND: Mortality associated with correction of type IV total anomalous pulmonary venous connection (TAPVC) is generally reported in combination with other anatomic types. The objective of this study is to review surgical outcomes associated with the repair of type IV TAPVC by analyzing a multi-institutional cohort specific for this group. We also analyze patient-specific variables that may contribute to poor operative outcomes. METHODS: A retrospective review of the Pediatric Cardiac Care Consortium (PCCC) registry identified patients who underwent repair of type IV TAPVC between 1982 and 2007...

Four red squirrels (Sciurus vulgaris) were subjected to necropsy examination over a 3-year period as part of a broader surveillance study. The squirrels presented with cutaneous, subcutaneous and/or internal swellings and nodules that consisted microscopically of sheets of atypical round cells and multinucleated giant cells. There was moderate anisokaryosis with rare mitoses. Nuclei ranged from oval to indented or C-shaped and some were bizarre, twisted or multilobulated. Many giant cells also had a bizarre morphology, with anisokaryosis within individual cells...

Anaplastic diffuse large B-cell lymphoma (A-DLBCL) is a rare morphologic variant characterized by the presence of polygonal, bizarre-shaped tumor cells. However, the clinicopathologic and genetic features of this variant are largely unknown. In this study, we investigated 35 cases of A-DLBCL with regard to their clinical, pathologic, and genetic characteristics. The age of the patients ranged from 23 to 89 years (median age, 62 y) with a male to female ratio of 23:12. Twenty-two of 26 (85%) patients had Ann Arbor stage III or IV disease, and 17/26 (65%) patients had a high-intermediate or high International Prognostic Index score...

An unusual case of a polypoid, malignant gastric tumor in a 62-year man is presented. Endoscopy and subsequent polypectomy revealed an 8.5 x 6.5 x 4.5cm lesion in the body of the stomach. Microscopy showed surface dysplasia with an invasive adenocarcinoma displaying prominent tubulopapillary areas composed of large vacuolated cells, pleomorphic nuclei and occasional cytoplasmic hyaline globules. This component then blended with tubular structures lined by more primitive appearing vacuolated cells embedded within a stroma made up of cellular primitive, high-grade blastema-like areas and, less cellular more pleomorphic foci with spindle and several bizarre, large cells...

Southwest Australia (SWA) is a global biodiversity hotspot and a centre of diversity and endemism for the Australo-Papuan myobatrachid frogs. Myobatrachus gouldii (the turtle frog) has a highly derived morphology associated with its forward burrowing behaviour, largely subterranean habit, and unusual mode of reproduction. Its sister genera Metacrinia and Arenophryne have restricted distributions in Western Australia with significant phylogeographic structure, leading to the recent description of a new species in the latter...

Adverse drug reactions (ADRs) represent a major health problem worldwide with high morbidity and mortality rates. ADRs are classified into type A (augmented) and type B (bizarre) ADRs with the former group being more common and the later less common but often severe and clinically more problematic due to their unpredictable nature and occurrence at any dose. Pediatric populations are especially vulnerable to ADRs due to the lack of data for this age group from the drug development process and because of the wide use of Off-label and unlicensed use of drugs...
