Using anti-CK7, the number of central bile ducts was 276 in primary biliary cirrhosis, 348 in chronic hepatitis, and 96 in miscellaneous cases. Central bile ducts with lumen were found in 93.0% of chronic hepatitis cases and in 89.5% of the miscellaneous cases, but in only 13.5% of the primary biliary cirrhosis cases. Peripheral bile ducts in groups of \u2265 4\/triad were found in all cases of chronic hepatitis (100%) and in 75.7% primary biliary cirrhosis cases, but only in 10.5% of the miscellaneous cases. In 21.6% of primary biliary cirrhosis cases, no bile ducts (central and\/or peripheral) were present.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:italic>Conclusions<\/jats:italic>\n                    \u2014Anti-CK7 detects bile ducts in the triads that are concealed by chronic inflammatory cells. Central and peripheral bile ducts in groups of \u2265 4 were significantly more common in primary biliary cirrhosis and chronic hepatitis than in other liver diseases. The lack of lumen in central bile ducts, as well as the absence of central and\/or peripheral bile ducts in CK7 stained liver sections, seem to be valuable additional parameters in the differential diagnosis between primary biliary cirrhosis and chronic hepatitis.\n                  <\/jats:p>","DOI":"10.1136\/jcp.53.10.765","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T06:37:59Z","timestamp":1027751879000},"page":"765-769","source":"Crossref","is-referenced-by-count":11,"title":["Qualitative and quantitative differences between bile ducts in chronic hepatitis and in primary biliary cirrhosis"],"prefix":"10.1136","volume":"53","author":[{"given":"C A","family":"Rubio","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2000,10,1]]},"reference":[{"key":"2025121403342014000_53.10.765.1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199611213352107"},{"key":"2025121403342014000_53.10.765.2","unstructured":"Portmann BC, MacSween RNM.
