CONTEXT - -Cardiac hepatopathy and Budd-Chiari syndrome are 2 forms of hepatic venous outflow obstruction with different pathophysiology but overlapping histologic findings, including sinusoidal dilation and centrilobular necrosis.
OBJECTIVE - -To determine whether a constellation of morphologic findings could help distinguish between the 2 and could suggest the diagnoses in previously undiagnosed patients.
DESIGN - -We identified 26 specimens with a diagnosis of cardiac hepatopathy and 23 with a diagnosis of Budd-Chiari syndrome. Slides stained with hematoxylin and eosin and with trichrome were evaluated for several distinctive histologic findings.
RESULTS - -Features common to both forms of hepatic outflow obstruction included sinusoidal dilation and portal tract changes of fibrosis, chronic inflammation, and bile ductular reaction. Histologic findings significantly more common in cardiac hepatopathy included pericellular/sinusoidal fibrosis and fibrosis around the central vein. Only centrilobular hepatocyte dropout/necrosis was significantly more common in Budd-Chiari, regardless of duration.
CONCLUSIONS - -The finding of pericellular/sinusoidal fibrosis in cardiac hepatopathy compared with Budd-Chiari is not unexpected, given the chronic nature of most cardiac hepatopathy. Portal tract changes are common in both forms of hepatic outflow obstruction and should not deter one from making the diagnosis of hepatic outflow obstruction. Fibrosis along sinusoids and around the central vein may be suggestive of cardiac hepatopathy in biopsies from patients without a prior diagnosis.
Image-guided percutaneous biopsy of abdominal masses is a safe, minimally invasive procedure with a high diagnostic yield for a variety of pathologic processes. This article describes the basic technique of percutaneous biopsy, including the different modalities available for imaging guidance. Patient selection and preparation for safe performance of the procedure is emphasized, and the periprocedural management of coagulation status as well as basic indications and contraindications of the procedure are briefly discussed. In particular, the role of biopsy in the diagnosis of liver and renal masses is highlighted.

BACKGROUND - Statins (3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors) are widely prescribed to reduce cholesterol levels. Studies have suggested that statins are associated with reduced risk of liver cancer, but much of the evidence is from regions of the world with high liver cancer incidence rates. The current study examined the statins-liver cancer relationship in a low-rate region and examined the effects of preexisting liver disease and diabetes on that association.
METHODS - A nested case-control study was conducted within the United Kingdom's Clinical Practice Research Datalink (CPRD). Persons diagnosed with primary liver cancer between 1988 and 2011 were matched to controls at a four-to-one ratio. Matches stratified on liver disease and on diabetes were also completed. Odds ratios (ORs) and 95% confidence intervals (CIs) for associations of statins with liver cancer were estimated using conditional logistic regression.
RESULTS - In total, 1195 persons with primary liver cancer were matched to 4640 control patients. Statin use was associated with a statistically significantly reduced risk of liver cancer (ORadj = 0.55, 95% CI = 0.45 to 0.69), especially among current users (ORadj = 0.53, 95% CI = 0.42 to 0.66). The reduced risk was statistically significant in the presence (ORadj = 0.32, 95% CI = 0.17 to 0.57) and absence of liver disease (ORadj = 0.65, 95% CI = 0.52 to 0.81) and in the presence (ORadj = 0.30, 95% CI = 0.21 to 0.42) and absence of diabetes (ORadj = 0.66, 95% CI = 0.51 to 0.85).
CONCLUSIONS - In the current study in a low-rate area, statin use was associated with a statistically significantly reduced risk of liver cancer overall. Risk was particularly reduced among persons with liver disease and persons with diabetes, suggesting that statin use may be especially beneficial in persons at elevated risk of liver cancer.

The 2005 National Institute of Health (NIH) Consensus Conference outlined histopathological diagnostic criteria for the major organ systems affected by both acute and chronic graft-versus-host disease (GVHD). The 2014 Consensus Conference led to this updated document with new information from histopathological studies of GVHD in the gut, liver, skin, and oral mucosa and an expanded discussion of GVHD in the lungs and kidneys. The recommendations for final histological diagnostic categories have been simplified from 4 categories to 3: no GVHD, possible GVHD, and likely GVHD, based on better reproducibility achieved by combining the previous categories of "consistent with GVHD" and "definite GVHD" into the single category of "likely GVHD." Issues remain in the histopathological characterization of GVHD, particularly with respect to the threshold of histological changes required for diagnostic certainty. Guidance is provided for the incorporation of biopsy information into prospective clinical studies of GVHD, particularly with respect to biomarker validation.

BACKGROUND - Hepatic endometriosis/uterus-like mass is rare and may be overlooked during hepatic cyst workups. We report a case of uterus-like mass, misdiagnosed as hepatic abscess.
CASE REPORT - A 47-year-old woman developed abdominal pain and vomiting. Infectious colitis with hepatic abscess was diagnosed, and remained antibiotic-refractory. Fine-needle aspiration and core biopsies showed benign contents. The patient presented to our institution with symptoms and normal blood work. Laparoscopic excision demonstrated a 1.4-cm cyst composed of endometrial glands (estrogen receptor+ and progesterone receptor+) and stroma (CD10+) with smooth muscle actin (SMA+), arranged in an organoid fashion. The patient, status-post hysterectomy, had no history or symptoms of endometriosis.
CONCLUSION - This rare case illustrates the merit of considering uterus-like mass/endometriosis in the differential diagnosis of antibiotic-refractory hepatic cysts. Cyst heterogeneity may confound needle biopsy. We report the first instance of a hepatic uterus-like mass, with a review of related entities, postulated histogenesis, and important clinical associations.

Patients with rheumatic diseases, including rheumatoid arthritis and osteoarthritis, almost universally describe pain and stiffness as important contributors to reduced health-related quality of life. Of the treatment options available, NSAIDs are the most widely used agents for symptomatic treatment. NSAIDs are effective anti-inflammatory and analgesic drugs by virtue of their ability to inhibit biosynthesis of prostaglandins at the level of the cyclooxygenase enzyme. However, many of the adverse effects of NSAIDs are also related to inhibition of prostaglandin production, making their use problematic in some patient populations. For the clinician, understanding the biology of prostaglandin as it relates to gastrointestinal, renal, and cardiovascular physiology and the pharmacologic properties of specific NSAIDs is key to using these drugs safely. Of particular importance is the recognition of co-morbid conditions and concomitant drugs that may increase the risk of NSAIDs in particular patients. In patients with risk factors for NSAID toxicity, using the lowest dose of a drug with a short half-life only when it is needed is likely to be the safest treatment option. For those patients whose symptoms cannot be managed with intermittent treatment, using protective strategies is essential.
Although dietary patterns, specific foods, and their constituents have been linked to cancer risk, the role of dietary patterns and specific food groups in liver cancer risk has not been investigated. In the Shanghai Women's Health Study (SWHS) and Shanghai Men's Health Study (SMHS), two cohort studies of 132 837 Chinese women and men, we evaluated the relationship between dietary patterns, food groups, and liver cancer risk. Through in-person interviews, dietary information intake over the preceding year was collected by using a validated food-frequency questionnaire. Cox regression model was used to estimate hazard ratios and 95% confidence intervals with adjustment for potential confounders. During an average follow-up of 10.9 (SWHS) or 5.5 (SMHS) years, 267 incident liver cancer cases were identified after the first 2 years of study enrolment. Three dietary patterns were derived by factor analysis. A vegetable-based dietary pattern was inversely associated with liver cancer; hazard ratios (95% confidence intervals) for the lowest to highest quartiles were: 1.00; 0.98 (0.71-1.35); 0.93 (0.67-1.29); and 0.58 (0.40-0.84); P(trend) = 0.01. The association was stronger among participants with a history of chronic liver disease. Further analyses showed high intakes of celery, mushrooms, allium vegetables, composite vegetables (including asparagus lettuce and garland chrysanthemum), legumes and legume products were associated with reduced liver cancer risk (all P(trend) < 0.05). Fruit- and meat-based dietary patterns were not associated with liver cancer risk. Our study suggests that a vegetable-based dietary pattern is associated with reduced liver cancer risk.
