We report a case of polymorphous hemangioendothelioma, a rare vascular neoplasm, arising in the liver of a 51-year-old woman. Microscopically, this neoplasm is characterized by a polymorphous blend of solid, primitive vascular and angiomatous areas in variable proportions. Polymorphous hemangioendothelioma is considered to be an intermediate-grade vascular neoplasm. In most of the reported cases, its occurrence has been in lymph nodes, but a few cases have been found in extranodal sites such as the mediastinum, spinal cord, and liver...

BACKGROUND: The population of the Pacific Melanesian country of Vanuatu was 234,000 at the 2009 census. Apart from subsistence activities, economic activity includes tourism and agriculture. Current completeness of vital registration is considered too low to be usable for national statistics; mortality and life expectancy (LE) are derived from indirect demographic estimates from censuses/surveys. Some cause of death (CoD) data are available to provide information on major causes of premature death...

Primary leiomyosarcoma arising from the ovarian vein is extremely rare, with only 10 cases reported in the literature. We report on a case of leiomyosarcoma of the left ovarian vein in a 67-year-old woman who presented with abdominal discomfort. Pelvic ultrasound revealed a large, solid, irregular mass in close relation to the left ovary. The patient subsequently underwent a total hysterectomy with bilateral salpingo-oophorectomy. Histologically, the tumor was composed of interlacing fascicles of spindle cells with abundant eosinophilic cytoplasm, hyperchromatic nuclei, and prominent nucleoli...

BACKGROUND/AIMS: We investigated the clinicopathological features of hepatic neuroendocrine tumours (NET) and neuroendocrine carcinoma (NEC), which remain largely unknown. MATERIAL AND METHODS: We examined 1235 tumours from 1048 patients who had undergone curative hepatectomy for liver neoplasms at Kurume University Hospital. Pathological diagnoses were based on the 2010 WHO Classification of Tumours of the Digestive System. We performed immunostaining for hepatocyte markers (eg, hepatocyte paraffin (HepPar)-1), neuroendocrine markers (eg, chromogranin A (CGA)) and the proliferation marker (Ki-67)...

Hepatitis C virus (HCV) cirrhosis is at a high risk of hepatocellular carcinoma (HCC), and its progression is influenced by a complex network of gene interactions. A weighted gene co-expression network was constructed to identify gene modules associated with the seven-stage disease progression from HCV cirrhosis to HCV-related HCC (n=65). In the significant module (R(2)=0.86), a total of 25 network hub genes were identified, half of which were also hub nodes in the protein-protein interaction network of the module genes...

Intraductal papillary neoplasm of the bile duct (IPNB) is a rare variant of bile duct tumors, characterized by papillary growth within the bile duct lumen and is regarded as a biliary counterpart of intraductal papillary mucinous neoplasm (IPMN) of the pancreas. IPNBs are mainly found in patients from Far Eastern areas, where hepatolithiasis and clonorchiasis are endemic. The Western experience, however, remains limited. In this article, we report a 56-year-old man, referred to our hospital because of deranged liver function tests...

BACKGROUND: Incidental small pancreatic cystic lesions (PCLs) are often found on pre-operative imaging in patients undergoing orthotropic liver transplantation (OLT).While these are considered benign or of low malignant potential, the influence of immunosuppression after OLT may be of concern. The aim of this study was to observe the long term outcome of these small pancreatic cystic lesions (PCLs) in post OLT patients. METHODS: An institutional OLT database of 1,778 consecutive OLT patients from January 2000 to December 2010 was analyzed...

As a significant cause of cancer death worldwide, colorectal cancer (CRC) is still one of the most common cancers in the world. The most efficient strategies to reduce CRC incidence include identifying risk factors for CRC and performing a preventive colonoscopy in high-risk populations. Some well-established risk factors for CRC development include hereditary syndromes and inflammatory bowel disease. Of note, in recent years, attention has been given to new evidence indicating that more than 75%-95% of CRC occurs in individuals with little or no genetic risk...

Multiple myeloma is a plasma cell tumor that homes to and expands in the bone marrow and that, despite the new available drugs, remains incurable. Extramedullary plasmacytoma is a not frequent manifestation during the natural history of multiple myeloma and is frequently associated with plasma cell bone marrow infiltration. The most common locations for an EMP include the gastrointestinal tract, pleura, testis, skin, peritoneum, liver, endocrine glands, and lymph nodes. Primary involvement of the gallbladder fossa is exceedingly rare...

Small intestinal neuroendocrine tumors (SI-NETs) are amine- and peptide producing neoplasms. Most patients display metastases at the time of diagnosis, they have an unpredictable individual disease course and the tumors are often therapy resistant. Chromogranin A (CgA) and 5-hydroxyindoleacetic acid (5-HIAA) are the clinically most used biomarkers today, but there is a great need for novel diagnostic and prognostic biomarkers and new therapeutic targets. Sixty-nine biomarkers were screened in serum from 23 SI-NET patients and 23 healthy controls using multiplex PLA (proximity ligation assay)...

Pancreatic neuroendocrine neoplasms (p-NENs) are slowly growing tumors with frequent liver metastasis. There is a variety of approaches to treat non-functional p-NENs with synchronous liver metastasis (LM) which complicates the determination of optimal treatment. Based on updated literature review, we discussed the treatment strategy determinants for p-NEN with LM. According to the resectability of primary tumor, the WHO 2010 grade classification and the radiological type of liver metastasis, the CSNET group reached agreements on a number of issues, including the following...

Hepatocellular carcinoma (HCC) is the commonest primary malignant neoplasm of the liver in most countries with a notoriously poor prognosis. Variation in global incidence is well-recognized and the occurrence of HCC is linked to several established environmental, dietary, and lifestyle factors. HCC demonstrates morphological heterogeneity both within the same tumor and from patient to patient. Differing architectural patterns and cytological variants may be seen. Inclusion bodies are believed to represent organized structures of proteins which contribute to their pathogenesis and share several constituents like chaperones, p62, ubiquitin, and Valosin containing protein...
