age distribution of hepatic tumors of sheep as well as study of their
histopathologic characteristics. For this purpose, 3000 slaughtered sheep,
consisting of 284 rams with approximate age of 7 to 20 months and 2716
ewes with approximate age of 3 to 7 years, were inspected during a routine
postmortem examination. This study was conducted at Tabriz abattoir in
the East Azerbaijan province of Iran, in a course of 8 months from March
to November 2006. In this survey, two livers were encountered tumoral.
Representative sections of the tumors were stained with hematoxylin and
eosin. Gross and microscopic features of these tumors supported diagnosis
of hepatocellular carcinoma and cholangiocellular carcinoma for a seven-years-old
crossbreed ewe and a five-years-old native breed ewe respectively. In
this survey, 0.074% of slaughtered ewes had hepatic neoplasia. That is,
the prevalence of hepatocellular carcinoma and cholangiocellular carcinoma
in aged ewes was equally 0.037% in this study.]]>Adler, R. and D.W. Wilson,199532415418Anderson, L.J. and A.T. Sandison,196721289301Bettini, G. and P.S. Marcato,19921071934Braun, U., P. Caplazi, T.
