Liver Partial Resection

Auto text: “Insert Liver Partial Resection”

Resections are performed either for benign tumors (hepatic adenoma, focal nodular hyperplasia, hemangioma):

Or malignancies (hepatocellular carcinoma, cholangiocarcinoma, metastatic tumors):

There will always be a cauterized cut surface representing the surgical margin, which should be inked (it usually appears shaggy). The smooth capsular surface should not be inked.


  1. If you receive a Liver status post TA​RE (Trans-Arterial Radioembolization), please consult a PA and read procedure UCMC 1145 in MediaLab (Handling Radioactive Specimens in the Gross Pathology Laboratory).
  2. Weigh and measure in three dimensions
  3. Ink surgical resection margin
  4. Serially section at 1 cm intervals
  5. Take a gross photograph of a slice of any interesting lesion
  6. Fix in formalin if desired.  These specimens can be grossed fresh or same day.


  1. Describe the number and sizes of all masses, and the condition of the surrounding parenchyma (i.e. cirrhosis)
  2. Measure distance of masses from surgical resection margin
  3. Take representative sections of tumor and surrounding parenchyma
