Piecemeal necrosis

Piecemeal necrosis generally refers to a necrosis that occurs in fragments.

Liver

When used in relation to the liver, piecemeal necrosis (also termed troxis necrosis,^[1] nibbling necrosis^[1] and interface necrosis^[1]) refers specifically to a loss and degeneration of hepatocytes at the lobular-portal-interface, producing a moth-eaten irregular appearance.^[2] Piecemeal necrosis of the liver is associated with a lymphocytic infiltrate^[2] into the adjacent parenchyma,^[3] and with destruction of individual hepatocytes along the edges of the portal tract.^[3]

It is a feature of viral hepatitis as well as autoimmune hepatitis and steatohepatitis.^[1]
