The aim of this study was to present our experience with primary breast angiosarcoma (PBA) by describing a large series of cases with an emphasis on clinicopathologic and radiologic correlations. Thirty-six cases of PBA diagnosed at our institution between 2006 and 2014 were retrospectively evaluated. All but one case occurred in women with a median age of 35.5 years. The majority of patients presented with a deeply located painless mass, whereas a minority manifested as diffuse enlargement or swelling of the breast...

Treatment-related neurotoxicity is a potentially life-threatening clinical condition that can represent a diagnostic challenge. Differentiating diagnoses between therapy-associated brain injury and recurrent disease can be difficult, and the immediate recognition of neurotoxicity is crucial to providing correct therapeutic management, ensuring damage reversibility. For these purposes, the knowledge of clinical timing and specific treatment protocols is extremely important for interpreting MRI patterns. Neuroradiologic findings are heterogeneous and sometimes overlapping, representing the compounding effect of the different treatments...

INTRODUCTION: Lung cancer incidence and mortality is higher among African Americans compared with European Americans in the USA where screening guidelines are currently in place and based on age at diagnosis and smoking history. Given the different smoking patterns observed in these populations and the earlier age at which African Americans are diagnosed, it is possible that African Americans will be disproportionally excluded from screening programmes. METHODS: We assessed the capture of African American and EA lung cancer cases using the National Lung Screening Trial, US Preventive Services Task Force and Centers for Medicare and Medicaid Services eligibility guidelines in a population of lung cancer cases diagnosed between 1998 and 2014 in the Baltimore region of Maryland (n=1658)...

: Insulin antibodies (IA) associated with exogenous insulin administration seldom caused hypoglycemia and had different characteristics from insulin autoantibodies (IAA) found in insulin autoimmune syndrome (IAS), which was first described by Dr Hirata in 1970. The characteristic of IAS is the presence of insulin-binding autoantibodies and related fasting or late postprandial hypoglycemia. Here, we report a patient with type 1 diabetes mellitus under insulin glargine and insulin aspart treatment who developed recurrent spontaneous post-absorptive hyperinsulinemic hypoglycemia with the cause probably being insulin antibodies induced by exogenous injected insulin...

Sclerosing mesenteritis is a rare pathology with only a few described cases in the literature. The etiology is unclear; however, several potential triggers, including abdominal surgery and abdominal trauma, have been discussed. The pathology includes a benign acute or chronic inflammatory process affecting the adipose tissue of the mesenterium. Despite it being a rare disease, sclerosing mesenteritis is an important differential diagnosis in patients after abdominal surgery or patients presenting spontaneously with signs of acute inflammation and abdominal pain...

BACKGROUND Extranodal lymphoma of the paranasal sinuses is a rare clinical entity seen in only 5-8% of extranodal lymphomas of the head and neck. Nasal natural killer/T cell lymphoma (Nasal NKTCL), which is a subtype of peripheral T cell lymphoma, constitutes about 1.4% of all lymphomas. NKTCL is usually diagnosed at a late stage because it presents with nonspecific symptoms in the early stages. CASE REPORT We report the case of a 25-year-old male patient who presented with periorbital swelling treated as fungal sinusitis but proven to have NKTCL...

A 62-year-old man with a 1-year history of numbness of the extremities, clumsiness, and gait disorder was diagnosed with cervical spondylotic myelopathy at a neighboring clinic and referred to our institution for surgery. The patient had undergone a total gastrectomy 6 years previously. Flattening of the cervical cord, associated with diffuse cervical spondylosis and intramedullary intensity change, was observed on magnetic resonance imaging of the cervical spine. Neurological examination revealed decreased vibratory and position sense in all limbs, with posterior funiculus-based neurological symptoms...

STUDY QUESTION: Is it possible to improve clinical visualization of phospholipase C zeta (PLCζ) as a diagnostic marker of sperm oocyte activation capacity and male fertility? SUMMARY ANSWER: Poor PLCζ visualization efficacy using current protocols may be due to steric or conformational occlusion of native PLCζ, hindering antibody access, and is significantly enhanced using antigen unmasking/retrieval (AUM) protocols. WHAT IS KNOWN ALREADY: Mammalian oocyte activation is mediated via a series of intracellular calcium (Ca(2+)) oscillations induced by sperm-specific PLCζ...

Pulmonary fibrosis (PF) is a chronic progressive lung disease without effective medical treatment options leading to respiratory failure and death within 3-5 years of diagnosis. The pathological process of PF is driven by aberrant wound-healing involving fibroblasts and myofibroblasts differentiated by secreted profibrotic transforming growth factor β (TGF-β1). Classical transient receptor potential 6 (TRPC6), a Na(+)- and Ca(2+)-permeable cation channel, is able to promote myofibroblast conversion of primary rat cardiac and human dermal fibroblasts and TRPC6-deficiency impaired wound healing after injury...

Connective tissues diseases (CTDs) can also be diagnosed early by "external" and safe imaging methods beyond the visceral organ analysis. This study aims to explore various imaging techniques used in diagnosing CTDs. Skin impairment in systemic sclerosis (SSc) may be recognized and studied by the modified Rodnan skin score (mRSS), which has some drawbacks, whereas high-frequency ultrasound (US) seems advantageous for the early identification of skin involvement. Salivary gland involvement in Sjögren syndrome (SS) can be assessed using standard tests such as unstimulated salivary flow test, salivary gland scintigraphy or contrast sialography...

A sort of PRCC with distinct eosinophilic cytoplasm named Oncocytic Papillary Renal Cell Carcinoma (OPRCC) has been increasingly attracting the attention of researchers recently. However, owing to the rarity of OPRCC, the clinicopathological and genetic features of the tumor have still not been well elucidated and whether it should be regarded as an independent subtype of PRCC remains controversial. Herein, a cohort of 14 OPRCCs was studied with the aim of revealing the distinct clinicopathological features, facilitating the classification and correct diagnosis of OPRCC...

Cholesterol granuloma (CG) is the most common benign lesion of the petrous apex, however, it can grow significantly large and become destructive causing a diagnostic dilemma. This case presents a 25-year-old female with 2-year history of left-sided progressive and profound hearing loss, a transient left-sided facial paralysis and cranial nerve 10 palsy who presented with a blue middle ear mass. Her diagnosis did not become apparent until direct visualization intraoperatively. The objective of this case study is to highlight the destructive capabilities of CG and the importance to keep it in the differential diagnosis of a large, erosive, expansile skull base lesion in order to avoid overly aggressive resection or other unnecessary treatment...

During the last 1.5 years an update of the guideline on silicosis was made by an interdisciplinary working group. New medical and scientific knowledge and the experience in expert opinion practice were taken into account.By preparing the initial guideline in 2010 standardization of diagnostics and adaption of the "Moers convention" which was not based on medical knowledge was in the focus, whereas the current update deals with fine emendation and extension, especially of the compensation rate (adaption with the Reichenhall recommendation)...

BRCA mutation carriers have a very high risk of breast and ovarian cancer by age 70, in the ranges 47%-66% and 40%-57%, respectively. Additionally, women with BRCA mutation-associated breast cancer also have an elevated risk of other or secondary malignancies. Fortunately, the breast and ovarian cancer outcome for BRCA1/2 mutation carriers is at least as good as for non-carriers with chemoprevention, prophylactic surgeries and appropriate use of therapies. Therefore, identification of those who might have a mutation is important so that genetic counseling, testing, screening and prevention strategies can be applied in a timely manner...

Atypical hemolytic uremic syndrome (aHUS), a thrombotic microangiopathy (TMA), is a rare, life-threatening, systemic disease. When unrecognized or inappropriately treated, aHUS has a high degree of morbidity and mortality. aHUS results from chronic, uncontrolled activity of the alternative complement pathway, which activates platelets and damages the endothelium. Two-thirds of aHUS cases are associated with an identifiable complement-activating condition. aHUS is clinically very similar to the other major TMAs: Shiga toxin-producing Escherichia coli (STEC)-HUS, thrombotic thrombocytopenic purpura (TTP), and disseminated intravascular coagulation (DIC)...

Here we present a case of an asymptomatic 53-year-old woman who sought genetic testing for Familial Creutzfeldt-Jakob Disease (fCJD) after learning that her mother had fCJD. The patient's mother had a sudden onset of memory problems and rapidly deteriorating mental faculties in her late 70s, which led to difficulties ambulating, progressive non-fluent aphasia, dysphagia and death within ∼1 y of symptom onset. The cause of death was reported as "rapid onset dementia." The patient's family, unhappy with the vague diagnosis, researched prion disorders online and aggressively pursued causation and submitted frozen brain tissue from the mother to the National Prion Disease Surveillance Center, where testing revealed a previously described 5-octapeptide repeat insertion (5-OPRI) in the prion protein gene (PRNP) that is known to cause fCJD...
