Cystadenofibroma with Mullerian-Type Epithelium and Stroma in the Liver: A Report of an Unusual Diagnosis and Discussion of Possible Etiologies.

Primary cystic neoplasms in the liver with ovarian type stroma typically represent mucinous cystic neoplasms. These tumors contain a cuboidal to columnar epithelium with variably mucinous cytoplasm. To the best of our knowledge, there are no reports of primary hepatic cystic neoplasms with ovarian-type stroma and ciliated epithelial lining.

Association of Histologic Disease Activity With Progression of Nonalcoholic Fatty Liver Disease.

Importance: The histologic evolution of the full spectrum of nonalcoholic fatty liver disease (NAFLD) and factors associated with progression or regression remain to be definitively established.

Objective: To evaluate the histologic evolution of NAFLD and the factors associated with changes in disease severity over time.

Design, Setting, And Participants: A prospective cohort substudy from the Nonalcoholic Steatohepatitis Clinical Research Network (NASH CRN) NAFLD Database study, a noninterventional registry, was performed at 8 university medical research centers.

Gene Expression Predicts Histological Severity and Reveals Distinct Molecular Profiles of Nonalcoholic Fatty Liver Disease.

The heterogeneity of biological processes driving the severity of nonalcoholic fatty liver disease (NAFLD) as reflected in the transcriptome and the relationship between the pathways involved are not well established. Well-defined associations between gene expression profiles and disease progression would benefit efforts to develop novel therapies and to understand disease heterogeneity. We analyzed hepatic gene expression in controls and a cohort with the full histological spectrum of NAFLD.
