Miliary brain metastasis is a rare type of brain metastasis, in which carcinoma cells disseminate to numerous foci confined to Virchow-Robin/subpial spaces. Symptoms usually progress within several months, and magnetic resonance imaging (MRI) shows multiple small contrast-enhancing lesions. We report an autopsy case of a patient who rapidly deteriorated within a week due to miliary brain metastasis after epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) discontinuation, without contrast-enhancing lesions on MRI...

Metastatic spread of cancer via the thoracic duct may lead to an enlargement of the left supraclavicular node, known as the Virchow node (VN), leading to an appreciable mass that can be recognized clinically - a Troisier sign. The VN is of profound clinical importance; however, there have been few studies of its regional anatomical relationships. Our report presents a case of a Troisier sign/VN discovered during cadaveric dissection in an individual whose cause of death was, reportedly, chronic obstructive pulmonary disease...

Salmonella is one of the most common foodborne pathogens worldwide. Salmonella infections in humans are mainly associated with consumption of poultry products contaminated with this foodborne pathogen. Therefore, strict sanitary measures are necessary to control Salmonella contamination during the slaughtering process of poultry. The objective of this study was to determine the occurrence and transmission of Salmonella at a series of steps in the slaughtering process of chicken. A total of 601 samples were collected from a series of slaughtering steps (10 sampling sites) of 26 chicken slaughterhouses throughout Korea...

In recent years, the interstitial cells telocytes, formerly known as interstitial Cajal-like cells, have been described in almost all organs of the human body. Although telocytes were previously thought to be localized predominantly in the organs of the digestive system, as of 2018 they have also been described in the lymphoid tissue, skin, respiratory system, urinary system, meninges and the organs of the male and female genital tracts. Since the time of eminent German pathologist Rudolf Virchow, we have known that many pathological processes originate directly from cellular changes...

Superior vena cava (SVC) cancerous thrombosis is extremely sparse, especially in the setting of extrathoracic tumours. Herein, we present the case of a patient with a squamous cell carcinoma of the tongue, who presented with SVC syndrome possibly secondary to symptomatic metastatic pericardial effusion. In this unique patient, the disastrous concurrence of all the elements of Virchow's triad within the confined anatomical space of SVC may have precipitated extensive vessel thrombosis with catastrophic consequences...

Treatment of patients with squamous cell carcinoma of the head and neck (SCCHN) is nowadays multidisciplinary. Therapeutic concepts include modern surgical and radiation techniques as well as systemic therapies. However, the prognosis of these patients is still poor for all stages. In the recurrent or metastatic situation after definitive therapy, there is an indication for palliative systemic treatment, whereby classical platinum-based chemotherapy and the monoclonal epidermal growth factor receptor (EGFR) antibody cetuximab are established, and immunotherapy (IO) has recently been proven a potent treatment option...

OBJECTIVE: Major depressive disorder is a frequent and disabling disease and can be treated with antidepressant drugs. When faced with severe or resistant major depressive disorder, however, psychiatrists may resort to electroconvulsive therapy (ECT). Although very effective, the response falls short of 100%. A recent meta-analysis established clinical and biological predictive factors of the response to ECT. We decided to explore neuroimaging biomarkers that could be predictors of the ECT response...

Polyamines serve a number of vital functions in humans, including regulation of cellular proliferation, intracellular signaling, and modulation of ion channels. Ornithine decarboxylase 1 (ODC1) is the rate-limiting enzyme in endogenous polyamine synthesis. In this report, we present four patients with a distinct neurometabolic disorder associated with de novo heterozygous, gain-of-function variants in the ODC1 gene. This disorder presents with global developmental delay, ectodermal abnormalities including alopecia, absolute or relative macrocephaly, and characteristic facial dysmorphisms...

Brain invasion by chronic lymphocytic leukemia (CLL) is very rare, and only a handful of cases have been reported. We here report a case of 61-year-old woman who had been treated for CLL for 14 years presenting with a progressive mental disturbance. Magnetic resonance imaging (MRI) showed discontinuous ring-enhancing lesions compatible with the "open ring" sign, which was considered a demyelinating disorder, in both the frontal lobes. However, on histological examination of the biopsied specimen, infiltration of small lymphocytes positive for CD5, CD20, and CD23, indicating brain invasion by CLL, was seen...

INTRODUCTION: In the 19th century Virchow described that metastasis to left supraclavicular lymph nodes (SLN) could originate in neoplasms located under the diaphragm. In the same way, right SLN metastasis are usually thought to arise from thoracic neoplasms. Our aims are to review our experience with metastatic SLN diagnosed by fine-needle aspiration cytology (FNAC) and to discuss the location of the primary in these cases. METHODS: We have reviewed all lymph node FNACs diagnosed in a single tertiary hospital between 2010 and 2017 and we have included all cases of metastatic SLN...

Cerebral perivascular spaces (PVSs), otherwise known as Virchow-Robin spaces, are interstitial fluid-filled channels, <2 mm in diameter that form around arterial perforators as they course from the cortex into the brain parenchyma. In contrast, a giant tumefactive PVS is a rare entity comprising of clusters of such channels larger than 15mm resembling a neoplastic process as the name suggests. We report a 55-year-old male who presented with unsteady gait, cognitive decline, and left lower limb weakness for 6 months...

INTRODUCTION: Acute mesenteric venous thrombosis is a rare but potentially fatal condition with superior mesenteric vein being the most common site of thrombosis development [1]. It is more common in patients with underlying disorders which cause disruptions to Virchow's Triad of hypercoagulability, stasis and endothelial injury. The disease is often associated with intestinal ischemia in its acute form, further complicating its management. PRESENTATION OF CASE: We present a case of acute superior mesenteric venous thrombosis resulting in jejunal ischemia in a 60-year-old Caucasian male with possible ulcerative colitis...
