'''Hepatitis B''' is a relatively common [[medical liver disease]] caused by the ''hepatitis B virus''. | |||
==General== | |||
*May lead to [[hepatocellular carcinoma]] without [[cirrhosis]]. | |||
*High prevalence. | |||
*Diagnosis is by serology - details of serologic testing are in the ''[[Medical_liver_disease#Hepatitis_B|medical liver disease article]]''. | |||
*A vaccination is available and done routinely in a many jurisdictions.<ref name=pmid21653306>{{Cite journal | last1 = Leuridan | first1 = E. | last2 = Van Damme | first2 = P. | title = Hepatitis B and the need for a booster dose. | journal = Clin Infect Dis | volume = 53 | issue = 1 | pages = 68-75 | month = Jul | year = 2011 | doi = 10.1093/cid/cir270 | PMID = 21653306 }}</ref> | |||

42 yo woman with bepatitis B virus, modified HAI necroinflammatory grade 5, modified HAI fibrosis stage 1. (would be Metavir activity index 1, fibrosis stage 1). A Triads (red arrows) are slightly cellular, without much interface inflammation, with occasional spots suggestive of spotty necrosis (black arrows). B. Triads, this one being the most expanded, show a mild infiltrate (HAI score 1) of lymphocytes and macrophages, with only a small amount present at the interface between triad and lobule. C. A maximum of two foci of spotty necrosis (arrows) were seen in a 10X field (HAI score 2). D. Occasional foci of zone 3 collapse (thick black lines, green arrows), HAI score 1, and piecemeal necrosis (blue arrows) HAI score 1, were seen. E. Trichrome shows portal fibrosis of most triads, but no bridges, or nodules (HAI stage 2). | |||

Hepatitis B virus. Metavir activity index 3 {PMN 2 LN 2]. Metavir fibrosis stage 4 (advanced fibrosis/cirrhosis). A. A fragmented specimen shows apparent nodules [black arrows]. B. Inflammatory cells extending from band suggest piecemeal necrosis [green arrows]; inflammatory foci apart from band denote spotty necrosis [blue arrows]. C. Reticulin stain shows piecemeal necrosis as black lines about hepatocyte clusters at band [blue arrows], regeneration as more than one cell thick cords [green arrows] and hepatocyte rosettes [magenta arrows]. D. On PAS without diastase, piecemeal necrosis can be seen as pink hepatocyte cytoplasmic fragments amid inflammatory cells [arrows]. E. The nodules seen at low power are confirmed to be collagen bounded, but the appreciation can be made frustrated by intense inflammation. F. Examination elsewhere shows a definite nodule pair amid fibrosis [green arrows]; note on the right the fibrous band extending from the portal triad [black arrow] with sinusoids being far more often perpendicular to the triad than they were in the regenerative nodules to the surrounding bands. | |||
