Histological grading and staging of chronic hepatitis.
This research presents a meta-analysis of Anatomia e Istologia Patologica, a large quantity of which has never before been published in a peer-reviewed journal, which aims to provide real-time information about the immune system’s response to disease. Expand
Formulation and application of a numerical scoring system for assessing histological activity in asymptomatic chronic active hepatitis
A Histology Activity Index has been developed which generates a numerical score for liver biopsy specimens obtained from patients with asymptomatic chronic active hepatitis that provides definitive endpoints for statistical analysis of serial changes in liver histology and offers an alternative to the use of conventional pathological descriptions.

Epithelioid hemangioendothelioma and related lesions.
The principal clinical, pathologic, and biologic differences among these three lesions of EH of soft tissue, bone, lung, and liver are discussed. Expand
Undifferentiated (embryonal) sarcoma of the liver. Report of 31 cases
Thirty‐one cases of undifferentiated (embryonal) sarcoma of the liver are presented, found predominantly in the pediatric age group, with a median survival of less than 1 year following diagnosis. Expand
Combined hepatocellular‐cholangiocarcinoma. A histologic and immunohistochemical study
Immunohistochemical (immunoperoxidase) staining for intracellular antigens showed that alpha‐fetoprotein is a fairly specific, although insensitive, marker of hepatocellular differentiation in primary liver cancers, being present in 50% of typical hepato cellular carcinomas and in hepatoCellular areas in 29% of combined tumors, but in no cholangiocarcinomas orcholangiocellular areas of combined tumor.

Biliary cystadenoma and cystadenocarcinoma. Report of 14 cases and review of the literature
The clinical and pathologic features and long‐term follow‐up of eight patients with biliary cystadenoma and six patients with biliary cystadenocarcinoma are reported and the previous literature isExpand
Epithelioid hemangioendothelioma of the liver
Epithelioid hemangioendothelioma (EHE) is a rare neoplasm of vascular origin that occurs in the liver and other organs; its etiology is unknown.
Epithelioid hemangioendothelioma of the liver: a clinicopathologic and follow-up study of 32 cases.
Although the prognosis is much more favorable than that for angiosarcoma, extrahepatic metastases occurred in nine of the patients in this series, and the biologic behavior of the tumor may be related in part to its matrix, which may show inflammation, dense sclerosis, and calcification. Expand
Hepatobiliary Cystadenoma and Cystadenocarcinoma: A Light Microscopic and Immunohistochemical Study of 70 Patients
Immunohistochemistry did not yield a diagnostic immunoprofile to distinguish Cystadenoma from cystadenocarcinoma or from other epithelial lesions arising within the abdominal cavity, suggesting that benign lesions may evolve into malignant ones in some patients. Expand
Isoniazid liver injury: clinical spectrum, pathology, and probable pathogenesis.
The clinical spectrum of isoniazid-induced liver injury seems to be clinically, biochemically, and histologically indistinguishable from viral hepatitis, except that the injury occurs primarily inExpand
