Leiomyoma with bizarre nuclei (LM-BN), is a variant of uterine smooth muscle tumor with atypical histologic features. Although some LM-BN share several significant genetic alterations with leiomyosarcoma, including p16 and p53, the underlying tumorigenesis of LM-BN remains largely unknown. As we previously reported, LM-BN can be divided into 2 subtypes, type I and type II, based on different nuclear features. Type I LM-BN have similar histologic features as uterine smooth muscle tumors with fumarate hydratase (FH) alterations...

Emperipolesis has recently been described as a constant feature of "biphasic squamoid" papillary renal cell carcinoma (BPRCC). We also noticed this in some high-grade (HG) RCC, which promoted the present study to estimate the incidence of emperipolesis in RCCs and to describe them in further detail. 14 cases of HGRCC showing emperipolesis were retrieved from our registry. Microscopic examination of filed slides was supplemented with immunohistochemical and molecular-genetic analyses using paraffin embedded tissue...

A 6-year-old girl was admitted to our hospital due to the presence of a slow-growing tumor in her right elbow. Biopsy specimens showed a round- to spindle-cell neoplasm with uncertain malignant potential, leading to the decision of surgical resection. Histologically, the resected tumor was encapsulated by fibrous tissue, but focally invaded the surrounding skeletal muscles. The tumor was composed of ganglion-cell-like short spindle cells with lymphocytic infiltration in the collagenous background. Tumor cells with large bizarre nuclei were occasionally observed, and multinucleated giant cells were scattered at the periphery...

The early history of cardiac catheterization has many interesting features. First, although it would be natural to assume that the procedure was initiated by cardiologists, two of the three people who shared the Nobel Prize for the discovery were pulmonologists, while the third was a urologist. The primary objective of the pulmonologists, André Cournand and Dickinson Richards, was to obtain mixed venous blood from the right heart so that they could use to use the Fick principle to calculate total pulmonary blood flow...

CONTEXT: The aim of the present clinical review was to illustrate the diagnostic difficulty associated with psychotic experiences during adolescence, in the light of the multiplicity of circumstances interplaying during this period. It was also intended to illustrate the observation that not all hallucinations occur in the context of a declared psychotic disorder. CASE REPORT: The patient was a 16-year-old adolescent girl who came to the Emergency Department of Coimbra Pediatric Hospital...

Refractory chronic colitis presents a medical and surgical challenge, and underlying etiologies are diverse with potential for misclassification as inflammatory bowel disease. We present an unusual case of chronic proctosigmoiditis with rare vascular etiology. A 48-year-old Caucasian male presented with severe diarrhea, weight loss, and abdominal pain. Computed tomography (CT) suggested proctosigmoiditis. Colonoscopy and biopsy findings were non-specific but were suggestive of ischemic etiology and venous congestion...

We report an autopsy case of intimal sarcoma arising in the pulmonary artery with focal chondrosarcomatous differentiation. A 77-year-old woman presented with a thrombosis-like mass in the pulmonary trunk and underwent endarterectomy. Macroscopically, solid and myxomatous tumor expanded to the pulmonary valve and bilateral main pulmonary arteries. Microscopically, the tumor comprised atypical spindle cells proliferating in a fascicular fashion, as well as occasional bizarre multinucleated cells, within a myxomatous stroma...

Purpose Cotyledonoid dissecting leiomyoma is a leiomyoma variant exhibiting unusual growth patterns. We aimed to demonstrate this, as well as to point out another feature that has not been previously reported. Case Report A congested, multinodular myomectomy specimen was resected. Histologically, smooth muscle fascicles with marked vascularity and extensive hydropic degeneration were detected. A total of 2 mitoses per 10 high power fields were counted, and the Ki-67 index was of 2-3%. We encountered atypical bizarre cells that have not been previously reported...

The current study aimed to evaluate the potentially traumatic aspects of psychotic symptoms and psychiatric treatment of psychosis using qualitative methods. Participants included 63 people with first episode psychosis or multiple psychotic episodes recruited from an inpatient psychiatric unit and an urban state psychiatric hospital in the North East region of the United States. Quasi-structured interviews were used to explore those aspects of symptoms and treatment that were perceived as traumatic Emotional reactions to the most traumatic aspect of symptoms and treatment, during and after the event, were also examined...

Rathke's cleft cysts (RCCs) are non-neoplastic, sellar or suprasellar epithelium-lined cysts originating from Rathke's pouch in the pituitary gland. Patients with RCCs are usually asymptomatic, but some have only been identified when symptoms manifested in middle age. The characteristics of these patients during childhood or adolescence remains unknown. We describe an 18-year-old girl who had occasionally suffered from malicious fatigue in the morning since her early teens. Brain magnetic resonance imaging (MRI) revealed T1 hyperintense/T2 hypointense signals between the anterior and posterior pituitary glands, indicating the presence of RCC...

Despite close ecological interactions between plants and their pollinators, only some highly specialised pollinators adapt to a specific host plant trait by evolving a bizarre morphology. Here we investigated the evolution of extremely elongated forelegs in females of the South African bee genus Rediviva (Hymenoptera: Melittidae), in which long forelegs are hypothesised to be an adaptation for collecting oils from the extended spurs of their Diascia host flowers. We first reconstructed the phylogeny of the genus Rediviva using seven genes and inferred an origin of Rediviva at around 29MYA (95% HPD=19...

A 51-year-old female who presented with obstructive jaundice was found to have masses in the pancreatic head and tail as well as suspicious liver and periaortic masses on imaging. Aspiration cytology of the pancreatic tail mass showed abundant large single cells with vacuolated eosinophilic cytoplasm, marked nuclear pleomorphism, large bizarre irregular nuclei, binucleation, and prominent nucleoli. Numerous cells also showed intracytoplasmic black to brown pigmentation. A cell block was obtained and extensive immunohistochemical staining was performed...

A 16-year-old boy presented with marked weight loss, weakness of the left extremities and dizziness of 2 months duration and vomiting for 2 days. Brain MRI showed an approximately 6.5 × 5.3 cm-sized huge heterogeneous enhancing mass located in the corpus callosum, extending into the lateral ventricle. Open biopsy showed that the lesion consisted of lymphoplasmacytes and plump histiocytes with rhabdoid morphology, which were stained with S-100 protein, CD68 (KP1) and negative for CD1a. Histiocytic tumor was initially diagnosed...

This report presents a bizarre and unusual case of looping and entrapment of a hydrophilic guidewire in the ureter of a 65-year-old woman with a stone in the lower ureter at the time of ureteroscopy and laser lithotripsy. We describe endourology maneuvers to remove the retained guidewire. Looping and entrapment of guidewire is a rare complication that urologists may face when they do not follow the basic principles of guidewire insertion. In that case, successful resolution is based both on surgeon's inspiration to apply the appropriate endourology maneuvers and availability of a variety of endourology tools in the theater...

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)...
