Adrenocortical adenomas and carcinomas in other parenchyma are extremely rare, with few cases reported and because of the rarity of these tumors, they occasionally cause problems during diagnosis. Adrenal cortical neoplasms in liver parenchyma can be present in 3 forms, including direct invasion or adhesion to liver parenchyma, tumors arising in adrenohepatic fusion tissue or in ectopic adrenal gland tissue. We report 3 cases of adrenal cortical tumors that were misdiagnosed as hepatocellular carcinoma in the preoperative state...

Neuroendocrine tumors (NETs) are rare neoplasms, with an estimated annual incidence of ~ 6.9/100,000. NETs arise throughout the body from cells of the diffuse endocrine system. More than half originate from endocrine cells of the gastrointestinal tract and the pancreas, thus being referred to as gastroenteropancreatic NETs (GEP-NETs). The only treatment that offers a cure is surgery; however, most patients are diagnosed with metastatic disease, and curative surgery is usually not an option. These patients can be offered long-term systemic treatment, for both symptomatic relief and tumor growth suppression...

BACKGROUND: Intrahepatic biliary cystadenomas are rare hepatic neoplasms, which are usually cystic. These tumors are often misdiagnosed as simple liver cysts and hydatid cysts clinically and radiologically owing to nonspecific clinical and radiologic features. These tumors require complete resection, as recurrence and malignant transformation can occur following incomplete excision. It is essential that these tumors be diagnosed accurately so that they can be adequately excised. METHODS: Clinical and radiological features of six cases of biliary cystadenoma are described...

Metabolic syndrome (MS) is one of the leading risk factors for the development of cardiovascular diseases, type II diabetes mellitus and reproductive system diseases. Currently, not only cardiovascular disease and reproductive history risks related with MS are frequently discussed, but it has been also shown that MS is associated with increased risk of some common cancers (endometrial cancer, postmenopausal breast cancer, colorectal cancer, biliary tract cancers and liver cancer for men). Further studies are required to understand the mechanisms of the involvement of MS components in the pathogenesis of malignant neoplasms...

Uveal metastasis is the most common intraocular malignancy. Lung cancer is one of the most common malignancies that metastasize to uvea. Iris involvement is rarely reported. Here we report a case of iris metastasis from pulmonary adenocarcinoma that was treated with photodynamic therapy (PDT). A 65-year-old Chinese man was referred to our hospital for iris white neoplasm and blurred vision for 2 weeks in his right eye. His accepted pulmonary lobectomy, radiotherapy and chemotherapy for pulmonary adenocarcinoma 1year ago and liver metastases were found 2 months earlier...

Pancreatic neuroendocrine tumours (PNETs) are a genomically and clinically heterogeneous group of pancreatic neoplasms often diagnosed with distant metastases. Recurrent somatic mutations, chromosomal aberrations and gene expression signatures in PNETs have been described, but the clinical significance of these molecular changes is still poorly understood, and the clinical outcomes of PNET patients remain highly variable. To help identify the molecular factors that contribute to PNET progression and metastasis, and as part of an ongoing clinical trial at the BC Cancer Agency (clinicaltrials...

Mucinous tubular and spindle cell carcinoma (MTSCC) is a relatively rare renal epithelial neoplasm. Although MTSCC is considered to be a low-grade and indolent neoplasm, aggressive cases have been recently reported. The present study discussed two additional cases of high-grade MTSCC causing multiple distant metastases with a fatal course. In case 1, a 71-year-old patient presented with hematuria and pyuria. Computed tomography (CT) scan of the right kidney revealed a mass lesion, for which partial nephrectomy was performed...

BACKGROUNDS: Perioperative fluid-therapy is a still a debated issue. In hepatic surgery, volume load must be strictly monitored to assure both a safe hemodynamics and low central venous pressure (CVP) to limit the backflow bleeding. Retrospectively, we compared intraoperative fluid management before and after the adoption of a semi-invasive hemodynamic monitoring. METHODS: We compared patients submitted to liver resection monitored by FloTrac/VigileoTM (group A) vs...

Interleukin-1 receptor 8 (IL-1R8, also known as single immunoglobulin IL-1R-related receptor, SIGIRR, or TIR8) is a member of the IL-1 receptor (ILR) family with distinct structural and functional characteristics, acting as a negative regulator of ILR and Toll-like receptor (TLR) downstream signalling pathways and inflammation. Natural killer (NK) cells are innate lymphoid cells which mediate resistance against pathogens and contribute to the activation and orientation of adaptive immune responses. NK cells mediate resistance against haematopoietic neoplasms but are generally considered to play a minor role in solid tumour carcinogenesis...

Fusion images of diffusion-weighted whole-body imaging with background body signal suppression and T2-weighted image (DWIBS/T2) demonstrate a strong signal for malignancies, with a high contrast against the surrounding tissues, and enable anatomical analysis. In the present study, DWIBS/T2 was compared with (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT) for diagnosing cancer in the abdomen. Patient records, including imaging results of examination conducted between November 2012 and May 2014, were analyzed retrospectively...

Grading of gastrointestinal neuroendocrine neoplasms (GI-NENs) relies mainly on mitotic activity and Ki-67 proliferation index. It is often difficult to predict metastatic potential of these neoplasms. Recent studies have shown that GI-NENs express a wide spectrum of microRNAs. We examined two microRNAs (miR-96 and miR-133a) that were recently identified in GI-NENs to determine if they could assist in evaluating the biological behavior of these neoplasms. A tissue microarray (TMA) was constructed with 51 primary GI-NENs, mainly from the small intestine and metastatic tumors from the same cases, including liver metastases (N = 20) and lymph node metastases (N = 33)...

OBJECTIVE: This article describes, illustrates, and correlates imaging and pathologic features of primary vascular mesenchymal neoplasms of the liver, which arise from the vascular endothelium and perivascular epithelioid cells. CONCLUSION: Familiarity with the spectrum of benign, malignant-potential and malignant vascular neoplasms, and nonneoplastic mimickers allows consideration in the differential diagnosis of enhancing hepatic masses. Understanding relevant pathologic features facilitates recognition of key imaging features, specifically dynamic contrast enhancement patterns on CT and MRI, which provide a useful classification system...

Colorectal cancer (CRC) is the third leading cause of cancer death in the Western world, accounting for approximately 140,000 new cases and more than 51,000 deaths in 2010 in the United States. In Kuwait, CRC is the first most-diagnosed neoplasm among males and overall, the second leading cause of death from cancer. The 5-year survival rate in 2002-2004 was 61% for men and 62% for women. Even after complete resection of the colorectal tumor, distant metastases have been noted to develop in 10%-15% of patients...

Primary liver neoplasms occurs relatively rarely in Poland. The most frequently occurring type of cancer is hepatocellular carcinoma (HCC), which globally constitutes 7% of all the occurrences of cancer. The incidence increases with age and is the highest in patients around the age of 70. It also varies significantly depending on the geographic location. The main factors that cause HCC are infection of HBV and HCV, whose genome integrates into the DNA of the host, causing mutations. The other factors include excessive alcohol consumption, contact or consumption of Aspergillus toxins as well as various metabolic disorders, such as α1-antitrypsin deficiency, hemochromatosis, tyrosinemia, porphyria, von Gierke disease and in person with gene mutation p...

INTRODUCTION: Hepatocellular adenoma (HCA) is a benign neoplasm of the liver, however, with a potential for life-threatening hemorrhage. The unpredictable course during pregnancy poses a clinical dilemma in the pregnant patient. Intra-peritoneal rupture may lead to life-threatening situations with adverse outcome for mother and unborn child. A pre-emptive strategy with adequate treatment before pregnancy is strongly advised. However, the strategy for treating symptomatic HCA during pregnancy remains challenging as experience is limited...

BACKGROUND: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract. Historically, a poor prognosis for metastatic disease has been reported with systemic chemotherapy. Significant advances have been made in the last decade, since the introduction of different tyrosine kinase inhibitors (TKIs). Unfortunately, even though the TKIs have been used for a long time, there are very few published data of the experience of TKI therapy in metastatic GIST from India...

Primary liver cancer (HCC) is recognized as the fifth most common neoplasm and the second leading cause of cancer death worldwide. Most risk factors are known, and the molecular pathogenesis has been widely studied in the past decade; however, the underlying molecular mechanisms remain to be unveiled, as they will facilitate the definition of novel biomarkers and clinical targets for more effective patient management. We utilize the B/D-HPP popular protein strategy. We report a list of popular proteins that have been highly cocited with the expression "liver cancer"...

A 44-year-old Filipino woman presented with abdominal pain and fever. Clinical examination and blood tests revealed no pathological results; however, (cross-sectional) imaging showed saccular cystic bile duct dilatation in the right liver with solid intraductal masses. Due to the clinical presentation the patient was admitted for surgical intervention with the diagnosis of Caroli disease. During the surgical procedure histopathology showed an intraductal papillary neoplasm of the bile duct (IPNB). The planned segmentetomy was extended to hemihepatectomy...
