Mammary liposarcoma is among the rarest of breast tumours. Here we report the presentation, macroscopic, microscopic, and immunohistochemical features of an extremely rare case of metaplastic carcinoma with extensive pleomorphic liposarcomatous differentiation. A 47-year-old woman presented with bilateral grade III breast ptosis and a 3 × 4 cm mass in the lower outer quadrant of the left breast. Mammography and ultrasound confirmed a well-defined mass. A core biopsy performed was diagnosed as pleomorphic liposarcoma...

Pritesh Jain, Dilip Kumar Pal
Pelvic retroperitoneum is a bizarre location of an epidermoid cyst and obstructive voiding caused by it even being stranger. Voiding symptoms related to such an abnormal location of cyst are extremely rare and literature that taps into such cases is scarce. We are presenting here a case of 26-year-old man who was presented with obstructive lower urinary tract symptoms and chronic constipation. On evaluation, he was found to have well-defined cyst in pelvic retroperitoneum. Complete excision of the cyst was done; histopathology confirmed it as an epidermoid cyst...

Spitz nevi, atypical Spitz tumors and Spitzoid melanoma, the three clinicopathologic forms that constitute the spectrum of the Spitz-type melanocytic lesions, share a histologic picture characterized by large spindle and/or epithelioid ganglion-like cells, with various admixtures of multinucleate bizarre cells. This remarkable cytology has always been interpreted as an unusual, as well as unexplained form of atypia. We report a case of atypical Spitz tumor with Homer Wright-like rosettes, a feature characteristic of ganglioneuroblastic proliferation...

Eutherian mammals-placentals and their closest extinct relatives-underwent a major radiation following the end-Cretaceous extinction, during which they evolved disparate anatomy and established new terrestrial ecosystems. Much about the timing, pace, and causes of this radiation remain unclear, in large part because we still know very little about the anatomy, phylogenetic relationships, and biology of the so-called 'archaic' eutherians that prospered during the ~10 million years after the extinction. We describe the first digital endocranial cast of a taeniodont, a bizarre group of eutherians that flourished in the early Paleogene, reconstructed from a computed tomography (CT) scan of a late Puercan (65...

REVIEW
Melanie G Rosen
Are dreams bizarre, nonsensical experiences or real-world simulations? I introduce a pluralist approach to dream content that highlights the philosophical and empirical implications of treating dreaming as a highly varied experience that can be anywhere on a spectrum from truly bizarre and incoherent to wake-like and mundane. Here I discuss several explanations for why theorists disagree on whether dreams should be defined as primarily bizarre or convincing, real-world simulations. Rating scales can underestimate or overestimate bizarreness depending on the variables of the scale and interpretation of contextual factors...

Clinical neurologists have long recognized that dementia can present as atypical or variant syndromes/symptoms. This study aimed at describing uncommon or bizarre symptoms/syndromes observed in patients suffering from dementia. Medline and Google scholar searches were conducted for relevant articles, chapters, and books published before 2018. Search terms used included compulsion, dementia, extracampine hallucination, disordered gambling, humour, and obsession. Publications found through this indexed search were reviewed for further relevant references...

The undead have a significant role in mythology, religion, folklore, and literature. In the 1800s, the word zombie was used to describe reanimated corpses in the Caribbean who often worked on plantations doing long, arduous field work. The movie White Zombie was released in 1932 and exploited this folklore, but it ignored the fact that zombies represent one outcome in Vodou religious beliefs regarding death and the migration of spirits following death. The interest in zombies eventually led to sociological and medical investigations into zombification...

The etiologies of bipolar disorder (BD) and schizophrenia include a large number of common risk alleles, many of which are shared across the disorders. BD is clinically heterogeneous and it has been postulated that the pattern of symptoms is in part determined by the particular risk alleles carried, and in particular, that risk alleles also confer liability to schizophrenia influence psychotic symptoms in those with BD. To investigate links between psychotic symptoms in BD and schizophrenia risk alleles we employed a data-driven approach in a genotyped and deeply phenotyped sample of subjects with BD...

Anecdotal evidence indicates that supplementation with vitamin B6 (pyridoxine) before bed can enhance dream vividness and recall. In a single pilot study, Ebben, Lequerica, and Spielman (2002) found that vitamin B6 had a dose-dependent effect of increasing scores on a composite measure of dream vividness, bizarreness, emotionality, and color. The present research replicated this study using a larger and more diverse sample of 100 participants from across Australia. We conducted a randomized, double-blind, placebo-controlled investigation of the effects on dreaming and sleep of ingesting 240 mg vitamin B6 (pyridoxine hydrochloride) before bed for five consecutive days...

A 27-year-old woman had progressive bony ankylosis over both hands since she was 5 years old. Bony ankylosing over the peripheral joints and spine slowly progressed, and scoliosis surgery was performed at age 14. Recently, she developed difficulty walking, changing position, and opening her mouth. A neurologist was consulted and ruled out the suspicion of narcolepsy. Chest CT showed ankylosing spondylitis. A bone scan showed a bizarre pattern with radiouptake to the left maxilla, bilateral sacroiliac joints, left middle third femur, and soft tissue uptake over bilateral arms, legs, and pelvis...

Bizarre parosteal osteochondromatous proliferation (BPOP) is a benign bone and cartilage forming tumor occurring on the surface of bones, predominantly on the hands and feet. A defining feature of BPOP is the purplish-blue mineralization of cartilaginous tissue, known as 'blue bone.' Here, we report on an institutional series of 16 cases of BPOP, including radiographic, histologic, and histomorphometric features. All tumors were composed of some element of bone, cartilage, fibrous tissue and 'blue bone,' though the amount of each tissue sub-type varied widely...

Ghost cell odontogenic carcinoma (GCOC) is a malignant odontogenic epithelial tumor which is an exceedingly rare, highly aggressive, rapidly growing, and infiltrative tumor forming the malignant counterpart of long-standing benign cystic lesions coming in the spectrum of calcifying odontogenic cysts. To date, only a few cases have been reported in the medical literature. A case of unusual presentation of GCOC is presented and the clinical, histopathological, and immunohistochemical features are discussed along with a literature review...

The evaluation of performance in scientific research at any level - whether at the individual, institutional, research council or country level - is not easy. Traditionally, research evaluation at the individual and institutional levels has depended largely on peer opinion, but with the rapid growth of science over the last century and the availability of databases and scientometric techniques, quantitative indicators have gained importance. Both peer review and metrics are subject to flaws, more so in India because of the way they are used...

Civilian perforating head injury is rare. Because rarity of this injury, there is no standard management protocol. We report a case of perforating head injury with iron rod, review the literature on the subject and discuss the challenges in the management of such case. We have not found similar case in the literature. Civilian perforating head injury is rare. A 25-year-male brought to the emergency department with approximately two feet perforating iron rod in the head, entering via frontal region, left side of midline and coming out of the occipital region...

The heat capacity of classical crystals is determined by the Dulong-Petit value CV ≃ D (where D is the spatial dimension) for softly interacting particles and has the gas-like value CV ≃ D/2 in the hard-sphere limit, while deviations are governed by the effects of anharmonicity. Soft- and hard-sphere interactions, which are associated with the enthalpy and entropy of crystals, are specifically anharmonic owing to violation of a linear relation between particle displacements and corresponding restoring forces...

Lucid dreaming (LD) is awareness that one is dreaming, during the dream state. However, some define and assess LD relying also on controlling dream events, although control is present only in a subset of lucid dreams. LD has been claimed to represent well-being, and has even been used as a therapeutic agent. Conversely, LD is associated with mixed sleep-wake states, which are related to bizarre cognitions, stress, and psychopathology, and have been construed as arousal permeating and disrupting sleep. We propose that previous conflicting findings regarding relations between LD and both psychopathology and well-being, stem from the non-differentiated assessment of frequency and control...

BACKGROUND: Comparative studies of neuroanatomy and neurodevelopment provide valuable information for phylogenetic inference. Beyond that, they reveal transformations of neuroanatomical structures during animal evolution and modifications in the developmental processes that have shaped these structures. In the extremely diverse Arthropoda, such comparative studies contribute with ever-increasing structural resolution and taxon coverage to our understanding of nervous system evolution...

Background: Past studies using the Bonn Scale for the Assessment of Basic Symptoms (hereafter, Bonn Scale) have shown that self-reported perceptual/cognitive disturbances reveal which persons have or will soon develop schizophrenia. Here, we focused specifically on the clinical value of self-reported visual perceptual abnormalities (VPAs) since they are underexplored and have been associated with suicidal ideation, negative symptoms, and objective visual dysfunction. Method: Using the 17 Bonn Scale vision items, we cross-sectionally investigated lifetime occurrence of VPAs in 21 first-episode psychosis and 22 chronic schizophrenia/schizoaffective disorder (SZ/SA) patients...

Unilateral frontalis muscle palsy is a debilitating disease with a heterogeneous etiology. Congenital or acquired unilateral paralysis of the frontalis muscle causes ipsilateral brow ptosis and contralateral hypermobility of the non-paralytic frontalis muscle, resulting in a bizarre asymmetry and emotional embarrassment. We present five patients with unilateral frontal muscle paralysis, two males and three females, aged between 32 and 68, treated with botulinum toxin A injection to the contralateral (non-affected) side...
