Liver cell adenoma: A case report with clonal analysis and literature review

Figure 1 CT scanning showing a lesion with reduction of density in the posterior part of the right lobe of liver.

Figure 2 Liver cell adenoma (× 400). A: Similar to normal hepatocytes, arranged in two-cell-thick cords separated by hepatic sinusoids (HE); B: Showing the border between LCA (lower) and surrounding liver parenchyma (upper) (HE); C: CK18 immunoreactivity (S-P).

Figure 3 Clonal analysis on tissues from 4 tumor areas (TAs). The pretreatment with Hha I results in loss of the upper band for TA₂ and TA₃, and intensity reduction by factors of 71.8% and 57.1% for TA₁ and TA₄, respectively. +, with Hha I pretreatment; -, without Hha I treatment.

Figure 4 Data of clonality test of three areas of liver parenchymal tissues (A₁-A₃). Neither of the bands on gel shows marked intensity change for the samples pretreated with Hha I (+) compared to those not treated (-).
