Liver biopsy may be considered to assess potential underlying cause(s). Cirrhosis, however, is not the only etiology of pHTN; in fact, schistosomiasis remains a significant factor worldwide. pHTN results from obstruction of hepatic blood flow; it is classified clinically based on either the anatomic location of obstruction or hepatic venous pressure gradient measurements. The clinical categories carry clinicopathologic significances. Histopathologically, pHTN is manifest with either cirrhotic or noncirrhotic features. Noncirrhotic pHTN results from a heterogeneous group of disease processes, all of which result in vascular remodeling with variable parenchymal nodularity and fibrosis. This review summarizes liver biopsy findings of cirrhosis and possible etiologies and provides a stepwise approach for the histologic differential diagnosis of a liver biopsy done for “cirrhosis.” Copyright © 2012 Wolters Kluwer Health, Inc.
