BACKGROUND: Shortened telomeres were found in patients with cirrhosis, probably reflecting chronic liver injury, continuous regeneration, and destruction of hepatic nodules. OBJECTIVES: To test whether telomere shortening is a general marker of cirrhosis, independent of disease etiology. METHODS: We evaluated telomere length in patients with cryptogenic cirrhosis (largely a late sequela of steatohepatitis) compared to patients with cirrhosis caused by chronic hepatitis B and C (HBV/HCV)...

Systemic hematopoietic disorders may present on liver biopsy, and rare cases of primary hepatic lymphoma (PHL) may be encountered. Hepatopathologists must be familiar with the full spectrum of hematopoietic disorders involving the liver and be prepared to exclude benign mimics. PHL, which is confined to the liver without extrahepatic involvement, can present as solitary or multiple nodules, raising consideration for carcinoma on imaging, or may mimic benign inflammatory conditions, posing a diagnostic challenge...

An 83-year-old woman was admitted to our hospital because of a space-occupying lesion (SOL) in the liver. Enhanced computed tomography (CT) showed a nodule measuring 20mm in size in the posterosuperior segment of the right hepatic lobe (S7) and another nodule measuring 14mm in size in the anterosuperior segment of the right hepatic lobe (S8). The margins of these nodules showed faint enhancement in the arterial phase and presented as low-density areas in the equilibrium phase. The S8 SOL could not be easily identified using ultrasonography (US)...

The current study presents the case of a 72-year-old woman with a rapidly enlarged liver metastasis from esophagogastric junction (EGJ) cancer, accompanied by progressive leukocytosis (47,680/µl) and elevated serum granulocyte colony-stimulating factor (G-CSF; 779 pg/ml). The patient underwent right hemihepatectomy 26 months after a total gastrectomy. On the seventh post-operative day the patient's leukocyte count and serum G-CSF level decreased to 4,280/µl and ≤19.5 pg/ml, respectively. Histologically, the lesion was a well to moderately differentiated adenocarcinoma similar to the primary lesion...

Background: Contrast-enhanced ultrasound imaging has been widely used in the ultrasound diagnosis of a variety of tumours with high diagnostic accuracy, especially in patients with hepatic carcinoma, while its application is rarely reported in thyroid cancer. The currently used ultrasound contrast agents, microbubbles, cannot be targeted to molecular markers expressed in tumour cells due to their big size, leading to a big challenge for ultrasound molecular imaging. Phase-changeable perfluorocarbon nanoparticles may resolve the penetrability limitation of microbubbles and serve as a promising probe for ultrasound molecular imaging...

BACKGROUND: The hepatic bridge forms a tunnel of liver parenchyma that may obscure peritoneal metastases associated with the round ligament. Visualization and then resection of nodules associated with this structure is necessary. MATERIALS AND METHODS: The incidence of a hepatic bridge and the extent that it covered the round ligament was determined in consecutive patients. Extent of coverage of the round ligament by the hepatic bridge was determined: Class 1 indicates up to one-third of the round ligament obscured, Class 2 up to two-thirds and Class 3 more than two-thirds...

Rationale. Pancreatic neuroendocrine tumors (NETs) are rare neoplasms that develop from the endocrine tissues of the pancreas. They have a better overall prognosis than pancreatic adenocarcinoma. However, all commonly used classification systems reflect a separation between more indolent, well-differentiated tumors and far more aggressive poorly differentiated types that behave clinically more like small-cell carcinoma of the lung. Objective. To present the case of a 62-year-old man with an aggressive pancreatic NET, with liver, splenic and bone metastases who underwent multidisciplinary treatment including several lines of chemotherapy, somatostatin analogs and radiotherapy...

Isolated macro-nodular liver tuberculosis is a very rare condition. It may mimic primitive or secondary tumors of the liver. This could delay or mislead the therapeutic management. An immunocompetent 48-year-old man with a history of non-metastatic seminoma was treated with right orchidectomy followed by 20 Gy radiotherapy. The discovery, 8 months later, of a 2 cm nodule of the hepatic dome evoked a liver metastasis. Percutaneous biopsy was not feasible. Wedge resection was performed whereas medical treatment would have sufficed, as pathologic examination of the resected specimen showed a macro-nodular hepatic tuberculosis...

The Liver Imaging Reporting and Data System (LI-RADS) standardizes the interpretation and reporting of imaging examinations in patients at risk for hepatocellular carcinoma (HCC). For focal liver observations it assigns categories (LR-1 to 5, LR-M, LR-TIV), which reflect the relative probability of benignity or malignancy of the respective observation. The categories assigned are based on major and ancillary image features, which have been developed by the American College of Radiology (ACR) and validated in many studies...

BACKGROUND: Published case series have described central hepatic macroregenerative nodules or masses as a common feature of Alagille syndrome. Our experience suggests this regenerative pattern can be seen more generally in cholangiopathic disorders. OBJECTIVE: To define the frequency of central regenerative tissue in Alagille syndrome and other cholangiopathic disorders and to describe the typical appearance of such regenerative tissue. MATERIALS AND METHODS: We conducted a retrospective study of CT and MR imaging performed in children and young adults with cholangiopathic disorders between January 2000 and June 2016...

Congestive hepatopathy (CH) arises from chronically elevated right sided heart pressures transmitted to the liver by passive venous congestion. Over time CH can lead to hepatic bridging fibrosis, decompensated cirrhosis, and hepatocellular carcinoma. Currently there are no evidence-based guidelines to direct appropriate screening or management of patients with CH partly because of the inability of current clinical tools (serum tests, imaging studies, liver stiffness measurements, and liver biopsy) to accurately estimate hepatic fibrosis or the risk for hepatic decompensation...

Splenosis is a benign condition that can occur after splenic trauma or after surgery involving the spleen. These splenic implants are most often seen within the abdominal and pelvic cavities. On imaging, splenosis can be confused with multiple additional entities including metastatic disease, peritoneal carcinomatosis, peritoneal mesothelioma, abdominal lymphoma, renal cancer, hepatic adenomas, or endometriosis depending on its distribution. In all patients with history of splenic surgery or trauma, splenosis should be on the differential diagnosis of soft tissue nodules in the abdomen and pelvis, especially in the absence of systemic symptoms, to avoid unnecessary biopsy, chemotherapy, or surgery...

The retrotransposon Long Interspersed Element 1 (LINE-1 or L1) is a continuing source of germline and somatic mutagenesis in mammals. Deregulated L1 activity is a hallmark of cancer, and L1 mutagenesis has been described in numerous human malignancies. We previously employed retrotransposon capture sequencing (RC-seq) to analyze hepatocellular carcinoma (HCC) samples from patients infected with hepatitis B or hepatitis C virus and identified L1 variants responsible for activating oncogenic pathways. Here, we have applied RC-seq and whole-genome sequencing (WGS) to an Abcb4 (Mdr2) -/- mouse model of hepatic carcinogenesis and demonstrated for the first time that L1 mobilization occurs in murine tumors...

Alginite is a non-ore raw material arising by fossilization of accumulated organic (algae) and inorganic material, particularly clay, carbonates, quartz, and amorphous modification of silicic acid in the aqueous environment. Humic acids as a component of organic portion of alginite are known for very good buffering ability which allows them to stabilise pH throughout the digestion system of animals, stimulate receptors of the immune system in intestinal villi against pathogenic bacteria, and support proliferation and activity of beneficial bacteria (lactobacilli, bifidobacteria, and similar)...

INTRODUCTION: The imaging diagnostics of liver tumor are difficult. There are no effective biopsy examinations for liver tumors that cannot be detected even by ultrasonography (US) and computed tomography (CT). We report a remarkably useful biopsy method for such tumors.

The differential diagnosis of hepatic mass lesions is broad and arriving at the right diagnosis can be challenging, especially on needle biopsies. The differential diagnosis of liver tumors in children is different from adults and is beyond the scope of this review. In adults, the approach varies depending on the age, gender, and presence of background liver disease. The lesions can be divided broadly into primary and metastatic (secondary), and the primary lesions can be further divided into those of hepatocellular origin and nonhepatocellular origin...
