Liver: Alcoholic Cirrhosis
Liver: Alcoholic Cirrhosis Portal cirrhosis; fatty degeneration. COMMENT: Specimens 13-22 are all examples of cirrhosis associated with alcoholism (Laennec's, portal, nutritional, alcoholic)--note that the specimens have a micronodular pattern in general with a generally uniform appearance to the nodules; however, note that some of the livers have nodules of up to about 1 cm. (see note below) and that there may be some variability in nodule size within one specimen. Intervening parenchyma is composed of fibrous septae. Also note that the remaining nodular liver parenchyma is quite pale or yellow = fatty change associated with continued alcohol abuse. Picture corresponding microscopic picture in your mind's eye of fatty change and cirrhosis (remember the definition of cirrhosis). Specimen #22 indicates that microscopically there is necrosis of hepatocytes with an inflammatory response = this is not evident grossly in this specimen. In this series, the small firm livers are good examples of end stage nutritional or alcoholic cirrhosis. NOTE: Although Robbins says that micronodular cirrhosis has nodules of up to 1 cm. in diameter, Dr. Hennigar's measurement of 3mm. and below is more characteristic.

Liver: Multiple Adenomas
Liver: Multiple Adenomas Multiple liver cell adenomas. COMMENT(#49 & #50): Good examples of multiple adenomas; areas of infarction/hemorrhage often found (remember microscopic characteristics).

Liver: Nodular Hyperplasia
Liver: Nodular Hyperplasia Focal nodular hyperplasia of liver.COMMENT: #46 and #48 have well developed scars in the presence of nodular liver tissue, these being the gross characteristics of this lesion (review microscopic characteristics).

Liver: Hepatocellular Carcinoma, Laennec's Cirrhosis
Liver: Hepatocellular Carcinoma, Laennec's Cirrhosis Hepatocellular carcinoma in Laennec's cirrhosis. COMMENT: Although more likely to occur in postnecrotic cirrhosis, can see this in Laennec's cirrhosis (mass in upper right = tumor)

Liver: Acute Hepatic Necrosis
Liver: Acute Hepatic Necrosis Acute hepatic necrosis secondary to occlusion of hepatic veins by renal cell carcinoma and thrombus ). COMMENT: Note thrombosed veins (arrows) and adjacent necrosis (dark areas). Remember tendency of renal cell carcinoma to invade vascular structures (i.e., renal veins to IVC and out hepatic veins).

Liver: Centrilobular Necrosis Massive centrilobular necrosis secondary to heart disease

Liver: Post-Necrotic Cirrhosis
Liver: Post-Necrotic Cirrhosis Post-necrotic cirrhosis with portal vein thrombosis. COMMENT: Specimens (#30-33) all illustrate, whatever the etiology may be, more coarsely nodular (macronodular) livers that usually seen with alcoholic or nutritional cirrhosis, with many of the nodules greater than 1 cm. Broad scars and irregular sized nodules are characteristic.

Liver: Post-Necrotic Cirrhosis
Liver: Post-Necrotic Cirrhosis Post-necrotic cirrhosis; 20 years carbon tetrachloride exposure. COMMENT: Faint fairly large nodules can be appreciated here; there is relatively little fibrosis appreciated grossly. COMMENT: Specimens (#30-33) all illustrate, whatever the etiology may be, more coarsely nodular (macronodular) livers that usually seen with alcoholic or nutritional cirrhosis, with many of the nodules greater than 1 cm. Broad scars and irregular sized nodules are characteristic.

Liver: Thorotrast Cirrhosis
Liver: Thorotrast Cirrhosis Thorotrast cirrhosis; hemangioendothelial sarcoma. COMMENT: Tumor nodules throughout-black or dark appearance in part due to thorotrast (No number)

Liver: Biliary Cirrhosis
Liver: Biliary Cirrhosis Biliary cirrhosis secondary to common bile duct atresia. COMMENT: (#36-#37): Biliary cirrhosis--two examples--of the secondary type, i.e., secondary to atresia (or obstruction) of extrahepatic or intrahepatic bile ducts. Both are examples of micronodular cirrhosis. In the first, ectasia of intrahepatic bile ducts can be appreciated. In the second, appreciate the blood-filled submucosal esophageal varices and the enormous spleen with focal subcapsular infarcts (at top) (compare size of spleen with esophagus to appreciate the splenomegaly).

Liver: Biliary Atresia
Liver: Biliary Atresia Biliary atresia in 3 y.o. with biliary cirrhosis, esophageal varices and congested spleen. COMMENT: (#36-#37): Biliary cirrhosis--two examples--of the secondary type, i.e., secondary to atresia (or obstruction) of extrahepatic or intrahepatic bile ducts. Both are examples of micronodular cirrhosis. In the first, ectasia of intrahepatic bile ducts can be appreciated.

Liver: Cardiac Cirrhosis
Liver: Cardiac Cirrhosis Cardiac cirrhosis. COMMENT: You would expect a centrilobular necrosis and fibrosis in cirrhosis resulting from right-sided heart failure. A resulting fine cirrhosis is present usually as in most of this specimen; however, there are a few areas of broader scars in the center of the specimen.
