Proliferative Activity (Visual Mitotic Counts, Image Cytometry of Phosphohistone 3 Stains) in Hepatic Adenoma and Hepatocellular Carcinoma

Hepatocellular Carcinoma in Sheep

Hepatocellular carcinoma arising in a telangiectatic hepatocellular adenoma.

Telangiectatic hepatocellular adenoma is a rare, recently recognized subtype of benign liver tumor that may very rarely undergo transformation into hepatocellular carcinoma. We report an unusual case of a 75-year-old woman with no history of oral contraceptive use that underwent malignant transformation of a telangiectactic hepatocellular adenoma. No risk factors for adenoma development were id...

the role of visual aids and translation in teaching vocabulary in est

the present study investigated the effect of the two vocabulary teaching techniques in est, namely the use of translation and the use of visual aids as two separate vocabulary teaching techniques. to answer the question of the study, a pretest (michigan test) was administered to the 58 randomly selected est students at khajeh nasiredin tusi university, faculty of mechanics. after the homogeneit...

Quantification of proliferative activity in colorectal adenomas by mitotic counts: relationship to degree of dysplasia and histological type.

AIM Proliferative activity of tumours reflects their malignant potential. In colorectal adenomas, a subjective impression of the number of mitoses is a criterion often used to assess the degree of dysplasia. Since these subjective impressions of mitotic activity may lack reproducibility, the aim of this study was to perform an objective analysis. METHODS Mitotic counts were conducted in tissu...

Hepatocellular carcinoma in a sheep

At necropsy of a five-year-old sheep, a pear shaped, lobular yellow-brownish mass measuring about 12 ×15 × 20 cm was found to involve the right hepatic lobe. Microscopic examination revealed two trabecularand solid patterns of neoplastic hepatocytes. In solid pattern, there were numerous tumoral giant cells thatcontain one or more large hyperchromatic bizarre-shaped nuclei scattered among clust...
