We read with great interest the leading article by Rosselli et al1 which offers a contemporary perspective to the clinical issue of interpreting progression (and regression) of chronic liver diseases (CLDs).

We fully agree with the view that the histological scoring of fibrosis is a reductive approach to the assessment of CLDs, as it does not fully reflect the complex events involved in the progression to cirrhosis. As suggested by Rosselli et al, a more insightful morphological analysis of liver biopsy should consider other important factors contributing to disease progression/regression, and possibly to cancer development. Angiogenesis represents one of such key factors.

Liver angiogenesis is a pathophysiological process characterised by changes in the phenotype of sinusoidal endothelial cells, which assume the features of capillary endothelial cells. This process, …
