Liposarcomas are rare mesenchymal tumors that usually develop in lower extremities or retroperitoneum; cervico-mediastinal presentation is quite uncommon. These neoplasms are commonly diagnosed at a late stage because they remain asymptomatic until nearby structures are compressed. This makes radical excision particularly challenging. To date, alternative chemoradiotherapy protocols have not yet been standardized. We report a case of a 55-year-old man with a right laterocervical mass and without substantial symptoms...

Splenic marginal zone lymphoma (SMZL) is a rare indolent B-cell neoplasm with hepatitis virus supposed to involve in the pathogenesis. The characteristics of SMZL derived from Caucasia population and high hepatitis C virus (HCV) infection region have been widely investigated, but few was reported in the Eastern population with HBV prevalent region. We analyzed the clinical characteristics, cytogenetic aberrations and prognostic factors in 160 SMZL patients from China. 25 patients (16%) were HBsAg-positive and 54 (34%) patients with resolved HBV infection...

George London was one of the most compelling vocal artists of the early twentieth century. At the age of 47, the great bass-baritone retired from singing. It has been suggested that the premature ending of his operatic career was due to unilateral vocal cord palsy (UVCP). When London retired, the common belief was that this UVCP was caused by viral hepatitis, although there is no evidence to support such an etiology. London's medical records eliminate the possible etiology of a neck neoplasm, and the long period of time between a heart attack he experienced and his diagnosis of UVCP makes a cardiovascular etiology an unlikely causative factor...

BACKGROUND AND AIMS: Gallbladder carcinoma is a rare but aggressive malignant neoplasm. The incidence of intra- or post-operative incidental gallbladder carcinoma diagnosis following laparoscopic cholecystectomy is estimated to be 1-2%. Aggressive re-resection is warranted as the majority of patients have residual disease either in the liver or the lymph nodes. However the use of a minimally invasive surgical approach (MISA) to perform a radicalization in these patients has not been investigated yet...

BACKGROUND: Pancreatic and hepatic mucinous cyst neoplasms (MCNs) have a malignant potential, but indolent MCNs are not uncommon. MATERIALS AND METHODS: The pathological and genetic characteristics of resected MCNs (n=15) categorized by the amount of mucin of the lining epithelium were investigated. RESULTS: MCNs were divided into two groups: (i) a rich (r)-MCN group (n=6), in which more than half of the epithelium was lined by abundant mucinous epithelium; and (ii) a poor (p)-MCN group (n=9), which consisted of the remaining cases...

Hepatocellular carcinomas are the most commonly reported neoplasm of black-tailed prairie dogs (Cynomys ludovicianus). In several other closely related Sciuridae species, infection with species-specific hepadnaviruses is associated with the development of these tumours, but such a hepadnavirus has not yet been identified in any prairie dog species, although its presence has been hypothesized previously. An adult prairie dog was humanely destroyed due to progressive illness and the identification of a cranial abdominal mass that was determined on histopathology to be a hepatocellular carcinoma...

The inflammatory cytokine interleukin (IL)-6, which basically activates the JAK/STAT signaling pathway, is well-known to repress expression of hepatic cytochromes P-450 (CYPs) and transporters. Therapeutic proteins, like mAbs targeting IL-6 or its receptor, have been consequently demonstrated to restore full hepatic detoxification capacity, which results in inflammatory disease-related drug-drug interactions (idDDIs). In the present study, we investigated whether ruxolitinib, a small drug acting as a JAK1/2 inhibitor and currently used in the treatment of myeloproliferative neoplasms, may also counteract IL-6 repressing effects towards hepatic detoxifying systems...

A number of benign and malignant neoplasms may arise from the vascular elements within the liver parenchyma. Lesions discussed in this article include angiosarcoma, epithelioid hemangioendothelioma, solitary fibrous tumor (hemangiopericytoma), infantile, and cavernous hemangiomas. Despite a common theme of vascular origin, the pathologic and imaging appearance of these entities can be heterogeneous. Angiosarcomas are bizarrely enhancing, highly aggressive tumors, which often present with metastatic disease...

Hepatocellular carcinoma (HCC) is a prevalent primary neoplasm of the liver, whose heterogeneous global incidence suggests the likely impact of genetic variations among individuals on the susceptibility to this disease. Increasing evidence indicates that melatonin exhibits oncostatic properties in many cancer types at least in part mediated by its membrane-bound receptors, melatonin receptor 1A (encoded by MTNR1A) and 1B (MTNR1B). In this study, the effect of melatonin receptor gene polymorphisms on the risk and progression of hepatic tumors was evaluated between 335 HCC patients and 1196 cancer-free subjects...

Non-Hodgkin lymphomas (NHL) comprise a heterogeneous group of B-cell and T-cell neoplasms. Diffuse large B-cell lymphoma (DLBCL), the most common type of NHL, accounts for around 30-40% of NHL cases. However, primary hepatic location of NHLs is rare and constitutes 0.01% of all NHL cases. Due to this rarity and a lack of large randomized trails, it is still unclear what treatment should be used for primary hepatic DLBCLs. In this study, we report of a female patient with primary hepatic DLBCL who was successfully treated with neoadjuvant chemotherapy and surgery...

Cholangiocarcinoma remains the second most prevalent hepatic neoplasm in the United States with a 5-year survival rate of less than 10%. Currently, no systemic therapy has demonstrated efficacy. Therefore, an urgent need for the identification of molecularly targeted compound(s) remains. The Notch signaling pathway has been shown to be dysregulated in cholangiocarcinoma, exhibiting hyperactivity while also possibly mediating chemotherapeutic resistance. We analyzed the effects of xanthohumol, a prenylated chalcone, on cholangiocarcinoma proliferation utilizing human cholangiocarcinoma cell lines CCLP1, SG-231 and CC-SW-1 while gaining insight into the associated mechanism...

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...

Jaundice in children is more often due to hepatic disease than obstruction. Differential considerations for obstructive jaundice in children include choledocholithiasis, choledochal cysts and rare neoplasms. Rhabdomyosarcoma, the most common soft tissue sarcoma in pediatric patients, typically involves the head and neck, genitourinary system and extremities. Embryonal rhabdomyosarcoma of the biliary tree is a rare entity. We present a 3-year-old boy with abrupt onset obstructive jaundice. Although initial imaging suggested a dilated biliary system with fusiform common bile duct, sludge, and possible cholelithiasis, endoscopic retrograde cholangiopancreatogram (ERCP) diagnosed a common bile duct embryonal rhabdomyosarcoma and further imaging showed involvement of the cystic duct...

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...

Ruxolitinib (Rux), a JAK1/2 inhibitor, has been approved for patients with myelofibrosis and in polycythemia vera with inadequate response/intolerance to hydroxycarbamide. Studies have demonstrated that Rux improves disease-related symptoms and splenomegaly. A late emerging observation from two Phase III trials was that Rux was associated with survival advantage in comparison with placebo or other available therapies in myelofibrosis. Important data suggest that for polycythemia vera Rux improved control of blood counts...

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...
