A review of lobular, portal, and periportal hepatitis. Interpretation of biopsy specimens without clinical data.

This representation, in which a recently adopted terminology is used, represents a compilation of clinical diagnoses that must be considered whenever a morphologic diagnosis of lobular, portal, or periportal hepatitis has been made. Also described are the morphologic findings that may enable the pathologist to list, without knowledge of clinical data, the suspected clinical conditions in an order of likelihood.
