Hepatocellular adenoma (HCA) was recently classified into four pathological subtypes. There have been few studies describing the findings of contrast-enhanced ultrasonography (CEUS) of each type. Our case concerns a 78-year-old man who had undergone routine medical check-ups for hepatitis C for 11 years. Abdominal ultrasonography showed a 28 mm, hypo-echoic mass in the segment 4 of the liver. His integrating amount of drinking was 670 kg convert into ethanol. CEUS with Sonazoid demonstrated mild uniform hypo-enhancement with inflow of microbubbles from the periphery of the tumor in the arterial phase, and heterogeneously hypo-enhancement in the post vascular phase...

BACKGROUND: It is well known that proliferating carcinoma cells preferentially use aerobic glycolysis rather than oxidative phosphorylation for energy production. Hexokinase 2 (HK2) plays a pivotal role in the glycolytic pathway. Previous studies have demonstrated that HK2 activity is markedly increased in various malignant neoplasms, but the clinical and biological significance of HK2 remain largely unclear in the colorectal carcinoma. PATIENTS AND METHODS: We performed immunohistochemistry for HK2 in 195 colorectal carcinoma tissues...

AIMS: Serum amyloid A is an acute phase reactant that is produced by hepatocytes in response to either inflammatory or neoplastic conditions. Because inflammatory adenomas produce this protein, serum amyloid A immunohistochemistry has been used in the evaluation of hepatocellular neoplasms. However, studies evaluating the expression of this protein in hepatitis are lacking. The aim of this study was to perform serum amyloid A immunostains on medical liver biopsy specimens of patients with common chronic liver diseases and correlate them with disease activity and stage...

The identification of somatic calreticulin (CALR) mutations can be used to confirm the diagnosis of a myeloproliferative disorder in Philadelphia chromosome-negative, JAK2 and MPL wild type patients with thrombocytosis. All pathogenic CALR mutations result in an identical C-terminal protein and therefore may be identifiable by immunohistochemistry. We sought to test the sensitivity and specificity of mutation specific immunohistochemistry for pathogenic CALR mutations using a commercially available mouse monoclonal antibody (clone CAL2)...

Hepatic angiomyolipoma is a rare neoplasm that can be difficult to diagnose in cases of ecoguide biopsy. We studied 4 cases of female patients with a mean age of 51 years. None of the patients presented specific abdominal symptoms, or other tumour masses detected by chance. One of them had relevant personal history: Renal cell carcinoma. This same patient was diagnosed with a contralateral renal angiomyolipoma. None of the patients showed evidence of tuberous sclerosis. Three tumours have been diagnosed by biopsy and only in one patient was decided to completely remove the tumour surgically...

Hepatoid adenocarcinoma (HAC) is the term proposed for a special type of extrahepatic tumors, which is similar to the hepatocellular carcinoma (HCC) both in the histopathology and immunohistochemistry. HAC has been observed in the stomach, colon, pancreas, gall bladder, lung and female genital tract, but rarely in the mediastinum. Now we describe a case of a 28-year-old Chinese male with primary mediastinal HAC with lung and liver metastasis. In this patient, HAC was associated with horseshoe kidney and idiopathic nonobstructive azoospermia...

Hepatocellular adenoma is considered to occur exclusively in non-fibrotic livers. It is a heterogeneous entity and a molecular classification is now widely accepted. The most frequent hepatocellular adenoma subtype, namely inflammatory adenoma, harbor somatic activating mutations of genes involved in the interleukin-6 pathway that lead to high C-reactive protein and serum amyloid A expression. The aim of our study was to investigate a series of benign hepatocellular neoplasms developed on cirrhotic livers and characterized by an unequivocal histological diagnosis...

INTRODUCTION: Male, 72-year-old, morbidly obese, diabetic, admitted for abdominal pain, prostration and fever that started last 3 days. Abdominal ultrasound and abdominal computed tomography scan showed liver injury in the transition of V and VI segments measuring 8.4 cm. Due to the possibility of liver abscess, initiate empirical antibiotic therapy with ampicillin and sulbactam and metronidazole and performed ultrasound-guided percutaneous drainage of liver injury. Negative for malignant cells, with the presence of leukocytes and negative culture...

A 17-yr-old boa constrictor (Boa constrictor constrictor) presented initially with diffuse gingival swelling, loose teeth, and loss of body condition. Examination under anesthesia revealed two firm pink masses within the oral cavity. The largest mass was removed for biopsy. Histopathology and Melan-A-positive immunohistochemistry labeling confirmed a diagnosis of amelanotic melanoma. Secondary stomatitis was treated with antibiotics to improve quality of life, but the snake's condition deteriorated quickly over the next 2 mo...

A dwarf bearded dragon (Pogona henrylawsoni) was presented with a white subcutaneous mandibular mass and multiple nodules in the oral mucosa, heart, liver, kidney, intestine, and visceral fat. Histologically, the tumor consisted of densely packed spindle-shaped cells with brow intracytoplasmic pigment that exhibited white-blue birefringence with polarized light. Immunohistochemical staining was negative for S-100 and weakly positive with melan A. Electron microscopic examination revealed cytoplasmic irregular and oblong empty spaces, laminated and often arranged into short stacks, compatible with reflecting platelet profiles typically seen in iridophores...

OBJECTIVES: To evaluate the rate, effect, and predictive factors of a complete pathologic response (cPR) in patients with hepatocellular carcinoma (HCC) undergoing locoregional therapy (LRT) before liver transplantation (LT). BACKGROUND: Eligible patients with HCC receive equal model for end-stage liver disease prioritization, despite variable risks of tumor progression, waitlist dropout, and posttransplant recurrence. Pretransplant LRT mitigates these risks by inducing tumor necrosis...

BACKGROUND/AIMS: Increased expression of polymeric immunoglobulin receptor (pIgR) in tumor tissue has been detected in various cancer forms. However, the clinical relevance of pIgR in colon cancer hepatic metastasis remains uncertain. The aim of this study was to assess the prognostic value of pIgR in patients with colon carcinoma hepatic metastasis after hepatic resection. METHODOLOGY: Genome-wide gene expression analysis was used to evaluate the expression of pIgR in cryopreserved tissue from liver metastases of colon cancer and in the corresponding primary colon cancer tissues from one patient with hepatic metastatic colon cancer...

Tumors with a rhabdoid phenotype are aggressive neoplasms with a dismal prognosis. Malignant extrarenal rhabdoid tumor (MERT) of the esophagus is an extremely rare disease with so far only 6 cases reported. We report on a 57-year-old male patient with rhabdoid tumor situated in the esophagus with metastases to the liver and local lymph nodes. Assuming an undifferentiated esophageal adenocarcinoma a palliative chemotherapy with 5-FU/folinic acid, oxaliplatin, and docetaxel (FLOT) was initiated which was changed towards a combination of doxorubicin and ifosphamide as immunohistochemistry of the primary and the liver metastases revealed a rhabdoid tumor...

Mitochondrial aldehyde dehydrogenase 2 (ALDH2) in the liver removes toxic aldehydes including acetaldehyde, an intermediate of ethanol metabolism. Nearly 40% of East Asians inherit an inactive ALDH2*2 variant, which has a lysine-for-glutamate substitution at position 487 (E487K), and show a characteristic alcohol flush reaction after drinking and a higher risk for gastrointestinal cancers. Here we report the characterization of knockin mice in which the ALDH2(E487K) mutation is inserted into the endogenous murine Aldh2 locus...

BACKGROUND: Primary ovarian and cervical melanomas are extremely rare tumors with a poor prognosis. Diagnosis requires a high index of suspicion as presentation can mimic benign conditions clinically and other neoplasms histologically. CASES: A 41 year-old with an adnexal mass underwent surgical staging for a stage IA ovarian melanoma. Imaging revealed a brain metastasis treated with radiation. Subsequent nodal recurrence was treated with immune and targeted therapies...
