From: Pigmented hepatocellular adenomas have a high risk of atypia and malignancy
Semiquantitative scoring of pigment deposition in pigmented hepatocellular neoplasms. (a) Score 1+: pigment deposition is focal, and is seen in a minority of 100 × fields. (b) Score 2+: the pigment is identified easily at 100 × magnification (majority of 100 × fields). (c) Score 3+: the pigment is easily identified at low power (40 ×) magnification. (d) Pigment appearance: high power (400 ×) examination of the pigment in pigmented hepatocellular neoplasms shows a granular brownish pigment deposited within neoplastic hepatocytes.
