If theatrophy of the hepatic cells is more considerable, rows of epithelialtubules and bands are found in the newly-formed connective tissue(Fig. 129, d) similar to those seen in acute yellow atrophy, andhaving also a like origin and significance.3.

It is sometimes further followed by a more orless extensive small-celled infiltration of the capsule of Glisson.When the tubercles develop in the vicinity of small bile-ducts, theepithelial cells of the latter may also take on growth and collecttogether in places into structures apparently composed of giant cells. Syphilis in adults occurs in the liver rarely in the form of ahepatitis distributed evenly over the entire organ, and recalling theappearances of cirrhosis. Usually it takes a more focal form, inwhich case we find on one or more spots, widely separated from eachother, an extensive sma
