INTRODUCTION: Benign cystic tumors represent only 2% of all pancreatic tumors (pancreatic cancer - PC). In contrast to malignant cystic tumors, these tumors occur typically in young women. A solid pseudopapillary tumor is a relatively rare affliction representing less than 4% of cystic PC. Although the tumor is considered benign, metastasis, especially to the spleen, has been reported in approximately 0.5-4% patients. Despite R0 resection, vascular and perineural invasion is monitored in 20% of cases...

Purpose: High mobility group box 3 (HMGB3) is associated with hepatocytes malignant transformation by our previous work. We continued to investigate the diagnostic and prognostic values of HMGB3 for hepatocellular carcinoma (HCC). Patients and methods: Circulating HMGB3 levels were quantitatively detected in a cohort of 225 patients with chronic liver diseases by ELISA and compared with alpha-fetoprotein by the receiver operating characteristic curve. HMGB3 expression in tissues of 170 HCC was detected by tissue microarray and immunohistochemistry...

Ledderhose disease or plantar fibromatosis is a rare hyperproliferative disorder of the plantar aponeurosis, clinically characterized by nodules situated especially on the medial border of the foot. It is histopathologically associated with Dupuytren's disease. This disease has some risk factors, like old age, alcohol or nicotine abuse, liver dysfunction, trauma or exposure to vibrations and autoimmune disorders, but the exact etiology is still unknown. Even though it is benign, the local manifestations can be aggressive, leading to debilitating deformities and contractures of the toes...

Breast augmentation is the most common cosmetic surgery in the United States. Squamous cell carcinoma (SCC) of the breast raises suspicion of possibly metastatic origin. Here, we report an unusual case of implant-associated SCC of the breast post silicone gel breast implant. The patient is a 46-year-old female with SCC of the breast. She initially had silicone gel breast implantation for breast augmentation in 1995. She had multiple revisions due to swelling and hardening. In 2016, she underwent bilateral prosthesis explantation and bilateral capsulectomy...

Background Liver cancer is the sixth most common cancer worldwide and the second leading cause of cancer mortality. Chronic liver disease caused by viral infection, alcohol abuse, or other factors can lead to cirrhosis. Cirrhosis is the most important clinical risk factor for hepatocellular carcinoma (HCC) whereby the normal hepatic architecture is replaced by fibrous septa and a spectrum of nodules ranging from benign regenerative nodules to HCC, each one of them with different imaging features. Conclusions Furthermore, advanced techniques including the quantification of hepatic and intralesional fat and iron, magnetic resonance elastography, radiomics, radiogenomics, and positron emission tomography (PET)-MRI are highly promising for the extraction of new imaging biomarkers that reflect the tumor microenvironment and, in the future, may add decision-making value in the management of patients with HCC...

Activation of the Hippo pathway effector Yap underlies many liver cancers, however no germline or somatic mutations have been identified. Autophagy maintains essential metabolic functions of the liver, and autophagy-deficient murine models develop benign adenomas and hepatomegaly, which have been attributed to activation of the p62/Sqstm1-Nrf2 axis. Here, we show that Yap is an autophagy substrate and mediator of tissue remodeling and hepatocarcinogenesis independent of the p62/Sqstm1-Nrf2 axis. Hepatocyte-specific deletion of Atg7 promotes liver size, fibrosis, progenitor cell expansion, and hepatocarcinogenesis, which is rescued by concurrent deletion of Yap...

Obesity, insulin resistance, and diabetes are strongly linked to the accumulation of excessive lipids in the liver parenchyma, a condition known as nonalcoholic fatty liver disease (NAFLD). Given its association with obesity and related metabolic diseases, it is not surprising that the prevalence of NAFLD has dramatically increased in the past few decades. NAFLD has become the most common liver disease in many areas of the world. The term, NAFLD, encompasses a spectrum of disorders that ranges from simple steatosis to steatosis with inflammatory lesions (nonalcoholic steatohepatitis [NASH])...

BACKGROUND: Minimal-invasive hepatectomy (MIH) has been increasingly performed for benign and malignant liver lesions with most promising results. However, the role of MIH for the treatment of patients with hepatocellular carcinoma (HCC) needs further investigation. METHODS: Clinicopathological data of patients who underwent liver resection for HCC between 2005 and 2016 were assessed. Postoperative outcomes und long-term survivals of patients following MIH were compared with those of patients undergoing conventional open hepatectomy (OH) after 1:1 propensity score matching...

Epilepsy is considered to be one of the most common non-communicable neurological diseases especially in low to middle-income countries. Approximately one-third of patients with epilepsy have seizures that are resistant to antiepileptic medications. Clinical trials for the treatment of medically refractory epilepsy have mostly focused on new drug treatments, and result in a significant portion of subjects whose seizures remain refractory to medication. The off-label use of cannabis sativa plant in treating seizures is known since ancient times...

Focal nodular hyperplasia (FNH) is the second most common liver cell-derived benign tumor. It is postulated that chemotherapy-induced hepatic circulatory abnormalities, like sinusoidal obstruction syndrome (SOS), could lead to the development of FNH. Cyclophosphamide was also reported to induce SOS in a synergistic effect with total body irradiation. However, none of cyclophosphamide-related FNH had ever been reported before. In this case report, we present a female patient who was treated with neoadjuvant chemotherapy of cyclophosphamide (500mg/m2 )-docetaxel (75mg/m2 )-pharmorubicin (90mg/m2 ) regimen every 3 weeks for breast cancer developed FNH after 4 courses of treatment...

Cholestasis refers to impairment in formation or excretion of bile. This can be due to defects in intrahepatic production of bile, defects in the transmembrane transport of bile, or mechanical obstruction to bile flow. Clinical features of cholestasis reflect the retention of components of bile (bilirubin, bile acids, cholesterol) in the body. In the neonatal period, hyperbilirubinemia can be categorized as either unconjugated (and often benign) hyperbilirubinemia, or conjugated hyperbilirubinemia due to cholestasis...

The liver disease focal nodular hyperplasia (FNH) has several histological features that resemble hepatic cirrhosis. Since cirrhosis may develop further into hepatocellular carcinoma (HCC) contrary to FNH, the aim of the present study was to identify microRNAs (miRNA), which, by their altered expression levels, may be associated with the benign, tumor-like nature of FNH. Altogether 106 surgically removed formalin-fixed paraffin-embedded liver samples were selected, including 22 FNH, 45 cirrhosis, 24 HCC and 15 normal liver tissues...

Histochemistry has an important, continuing role in the current assessment of hepatic biopsies and resection specimens. The evaluation of connective tissue elements in the liver can be accomplished with such methods as the Masson trichrome, Snook reticulin, Vierhoff van Gieson, orcein, and Victoria blue stains. The results contribute to the diagnosis of acute and chronic hepatitis, submassive necrosis, venous outflow obstruction, steatohepatitis, and cirrhosis. Fat stains done on frozen sections of liver tissue are routinely performed in the evaluation of donor liver allograft biopsies...

Hepatocellular adenoma is a rare benign liver tumor. Predisposing factors include hepatic storage diseases and some genetic conditions. A new histology-based classification has been proposed but to date, the corresponding ultrasound imaging features have not been reported. Here we review the new classification scheme and discuss the corresponding features on contrast-enhanced ultrasound imaging.

INTRODUCTION: Up to 38% of pancreatic and periampullary cancer patients undergoing curative intended surgery turn out to have incurable disease. Therefore, staging laparoscopy (SL) prior to laparotomy is advised to spare patients the morbidity, inconvenience and expense of futile major surgery. The aim of this study was to assess the added value of SL with laparoscopic ultrasonography (LUS) and laparoscopic near-infrared fluorescence imaging (LFI). METHODS: All patients undergoing curative intended surgery of pancreatic or periampullary cancer were included prospectively in this single arm study...

BACKGROUND: Metastases to the liver are often the first finding in patients with uveal melanoma with extraocular disease, but little has been published on the utility of staging MRI at initial diagnosis. We aimed to evaluate the proportion of abnormal hepatic findings on baseline MRI and accuracy of MRI in patients with newly diagnosed uveal melanoma. METHODS: This is a single-centre, retrospective, institutional review board-approved study of 145 consecutive patients diagnosed with uveal melanoma, at Memorial Sloan Kettering Cancer Center between 2004 and 2016, who had staging MRI within 1  month of diagnosis...

We prospectively evaluated the effectiveness of contrast-enhanced ultrasonography (CEUS) for differentiation of benign versus malignant portal vein thrombosis (PVT). We studied a total of 43 patients with chronic liver disease, hepatocellular carcinoma-suggestive nodules and confirmed PVT, in whom the nature of the PVT was confirmed by follow-up imaging (US, computed tomography and/or magnetic resonance imaging) performed up to 6 mo after CEUS. PVT was assessed by US, Doppler US and CEUS with respect to vessel wall disruption and/or invasion, color Doppler vascularization, pulsed Doppler vascularization pattern and CEUS enhancement and vascularization pattern, and thrombi were classified as benign or malignant based on these findings...

Feature selection is a significant preprocessing method in the classification part of an expert system. We propose a new Multiswarm Heterogeneous Binary Particle Swarm Optimization algorithm (MHBPSO) using a Win-Win approach to improve the performance of Binary Particle Swarm Optimization algorithm (BPSO) for feature selection. MHBPSO is a cooperation algorithm, which includes BPSO and its three variants such as Boolean PSO (BoPSO), Self Adjusted Hierarchical Boolean PSO (SAHBoPSO), and Catfish Self Adjusted Hierarchical Boolean PSO (CSAHBoPSO)...
