Transitional cell carcinoma (TCC) urinary bladder is known to metastasize to regional lymph nodes (LNs), liver, lung, bone, adrenal glands, and intestine. However, an asymptomatic TCC bladder manifesting as metastatic axillary LN mass and extensive retroperitoneal lymphadenopathy is rarely heard of. A 46-year-old male, smoker, presented with 8 cm × 6 cm right axillary swelling of 1-month duration. Aspiration cytology revealed metastatic deposits of poorly differentiated carcinoma favoring TCC. Metastatic evaluation with (18)F-fluorodeoxyglucose positron emission tomography ((18)FDG-PET) scan showed mass lesion urinary bladder, conglomerate right axillary mass and extensive retroperitoneal LNs with significant metabolic activity, biopsy from which revealed deposits of TCC...

Paraneoplastic hepatopathy has been reported with various malignancies, most commonly with renal cell cancer. This non-metastatic hepatic dysfunction in such malignancies is known as Stauffer syndrome. We describe a 61-year-old man who presented with symptoms of bowel obstruction with marked cholestasis and high levels of alkaline phosphatase and bilirubin. Imaging revealed an unremarkable liver and a mass in the ileocecal valve with mesenteric lymphadenopathy. Biopsies were consistent with a carcinoid tumor...

Heat stress negatively affects cow performance, compromises immune function, and increases susceptibility to metabolic disorders, particularly during the dry period and as cows transition from gestation to lactation. Metabolic adaptations of the liver are critical for successful transition, yet it is unclear how heat stress affects metabolic pathways within the liver at the proteomic level. The objective of this study was to investigate the liver proteome of postpartum cows that were cooled or heat stressed during the dry period to gain insight into how protein expression is altered by prior heat stress and may contribute to performance and disease outcomes...

A 78-year-old man with a history of benign prostatic hyperplasia presented with double vision, facial pain, altered taste and headache for 7 weeks. Neurological exam was notable for palsies of the right V, VI, VII and XII cranial nerves. An expansive clival mass and multiple lesions in the vertebra were found on MRI. Radionuclide studies showed extensive tumour burden in his liver and peritoneum. His serologies showed normal carcinoembryonic antigen and carbohydrate antigen 19-9 levels and modestly elevated prostate-specific antigen, which was a red herring...

A 70-year-old man with history of heart transplant performed in 1986, presented with altered mental status. CT scan of brain showed ring-enhancing lesions, raising suspicion for metastatic malignancy. Work-up revealed bilateral adrenal masses, biopsy showed granulomatous changes consistent with histoplasmosis. The possibility of histoplasmosis was less likely as the patient had no prior history of symptomatic disease and had lived in the endemic area 30 years prior to presentation. Brain biopsy confirmed central nervous system involvement...

BACKGROUND & AIMS: Magnetic resonance elastography (MRE) and transient elastography (TE) are noninvasive techniques used to detect liver fibrosis in NAFLD. MRE detects fibrosis more accurately than TE, but MRE is more expensive, and the concordance between MRE and TE have not been optimally assessed in obese patients. It is important to determine under which conditions TE and MRE produce the same readings, so that some patients can simply undergo TE evaluation to detect fibrosis. We aimed to assess the association between body-mass-index (BMI) and discordancy between MRE and TE findings, using liver biopsy as the reference, and validated our findings in a separate cohort...

Lung cancer during pregnancy is a rare condition. We report a case of 28-year-old nonsmoker female, who was admitted to our hospital with massive left pleural effusion in the 21st week of gestation. Chest radiograph showed total left hemithorax opacity with contralateral mediastinal deviation. Pleural biopsy and cytological examination of pleural fluid revealed adenocarcinoma invasion with positive epidermal growth factor receptor mutation status. Cesarean section was performed at 32 weeks of pregnancy, and targeted therapy was given to this patient after delivery...

Retroperitoneal fibrosis is a rare condition characterized by chronic inflammation and marked fibrosis of the retroperitoneal tissue, often leading to entrapment of abdominal organs. We report a 69-year-old white man who presented with a 5-week history of gradual onset of progressive abdominal distension. He had no history or risk factors for an underlying liver condition. Ascites and a retroperitoneal mass encasing the major abdominal vessels were revealed on imaging. Biopsies of the mass confirmed the presence of retroperitoneal fibrosis, and the ascitic fluid was milky, consistent with chylous ascites...

Nonalcoholic fatty liver disease is becoming the most common chronic liver disease in Western countries, and limited therapeutic options are available. Here we uncovered a role for intestinal hypoxia-inducible factor (HIF) in hepatic steatosis. Human-intestine biopsies from individuals with or without obesity revealed that intestinal HIF-2α signaling was positively correlated with body-mass index and hepatic toxicity. The causality of this correlation was verified in mice with an intestine-specific disruption of Hif2a, in which high-fat-diet-induced hepatic steatosis and obesity were substantially lower as compared to control mice...

Non-Hodgkin lymphoma often involves the liver. However, primary hepatic lymphoma (PHL) confined to the liver without evidence of lymphomatous involvement is rare. The optimal therapy for PHL is still unclear. Most patients present with poor prognostic features. Here, we report a case of PHL treated with liver resection followed by chemotherapy. A 65-year-old male was referred for further evaluation about a liver mass detected on ultrasound. Abdominal computed tomography (CT) scan showed well-defined single mass of 6 cm in diameter...
