Objective: To determine if the hepatobiliary phase of gadoxetate disodium-enhanced hepatic MRI increases the sensitivity in differentiating focal nodular hyperplasia from hepatocellular adenomas. Design: Prospective analysis. Methods: This study was comprised of 52 patients (2 men, 50 women) with suspicion of hepatocellular adenomas or with focal nodular hyperplasia on a previous CT or conventi...

Appendiceal Mucocele is a condition where luminal distention occurs due to mucin accumulation within the appendiceal lumen. This usually results from either benign epithelial proliferation such as; hyperplasia and Lowe-Grade Mucinous Neoplasm or malignant as: cystadenocarcinoma

A light and electron microscopic study was conducted on dorsal fin tissues adjacent to acute fin erosion lesions in winter flounder from 2 polluted sites (New York Bight region and New Haven Harbor) on the northeast Atlantic Coast. The objective of this work was to evaluate these minimally affected, lesion-associated tissues which may precede the acute or severe stages of the disease. The follo...

Psoriasis vulgaris is a common skin disorder characterised by focal formation of inflamed, raised plaques that constantly shed scales derived from excessive growth of skin epithelial cells. The disease is defined by a series of linked cellular changes in the skin: hyperplasia of epidermal keratinocytes, vascular hyperplasia and ectasia, and infiltration of T lymphocytes, neutrophils, and other ...

Hepatocellular lesions can be neoplastic or non-neoplastic. The common non-neoplasms include regenerative hyperplasia, focal accumulation of fat, focal nodular hyperplasia (FNH), macroregenerative nodules (MRN), and nodular regenerative hyperplasia (NRH). The neoplasms include hepatic adenomas, hepatocellular carcinomas (HCC) and their variants. Accurate diagnosis of these lesions can be someti...

Epithelial inclusions were detected in myocardium of a 2-month-old male Holstein calf. Microscopically,nonpurulent myocarditis along with focal tubular and acinar structures covered with cuboidal epithelial cellswas seen in the myocardium. Most tubular and acinar structures stained with Masson’s trichrome were foundto be surrounded with a dense collagen. Tubular and acinar structures had PAS po...

the toxic impact of copper sulfate in lethal and sublethal concentrations was investigated on gill of grass carp, ctenopharynogodon idella . in this investigation, 27 specimens were used as control group and three treatment groups were treated with 2.5 and 5mg/l of copper sulfate. gill samples were collected from each treatment after 96hr and lesions were analyzed by light microscopy. in histop...
