Recent Advances in the Histopathology of Drug-Induced Liver Injury
Drug-induced liver injury (DILI) is constantly changing as new drugs are approved and as new herbals and dietary supplements (HDS) reach the market. The pathologist plays a key role in the evaluation of DILI by classifying and interpreting the histologic findings considering patients ’ medical history and drug exposure. The liver biopsy findings may suggest alternative explanations of the injury and additional testing that should be performed to exclude non-DILI causes. Recent reports of iatrogenic liver injury are reviewed with attention to immunomodulatory and antineoplastic agents as well as reports of injury asso...

Primary Biliary Cholangitis and Autoimmune Hepatitis
Primary biliary cholangitis and autoimmune hepatitis are common autoimmune diseases of the liver. Both have typical clinical presentations, including certain autoantibodies on serologic testing. Histologic features are also often typical: primary biliary cholangitis shows bile duct destruction (sometimes with granulomas), and autoimmune hepatitis shows prominent portal and lobular lymphoplasmacytic inflammation. Both have a wide differential diagnosis, including one another; they may also simultaneously occur within the same patient. Careful use of clinical and histologic criteria may be necessary for diagnosis. First-line...

Acute, Chronic, and Humoral Rejection
Under current immunosuppressive regimes, T-cell –mediated acute and chronic rejection remain common and important posttransplant complications. The definition of humoral (antibody-mediated) rejection has been greatly expanded in recent years. The histopathologic assessment of allograft biopsies continues to serve an important role in the diagno sis of rejection and to facilitate patient management. The diagnosis of both acute and chronic antibody-mediated rejection requires integration of the results of donor-specific antibody testing and C4d immunostaining, as well as exclusion of other potential etiologies of allog...

Nonalcoholic Steatohepatitis
Nonalcoholic fatty liver disease (NAFLD) is a major health concern and the prevalence continues to increase in many industrialized and developing countries around the world. NAFLD affects adults and children. NAFLD-related cirrhosis is expected to become the top indication for liver transplantation in the near future, and the incidence of NAFLD-related hepatocellular carcinoma is also increasing. Nonalcoholic steatohepatitis is the more severe form of NAFLD. The pathogenesis of NALFD/nonalcoholic steatohepatitis is complex and new concepts continue to evolve. The diagnosis and categorization of nonalcoholic steatohepatitis...

Hepatic Pathology: Evolving Concepts in Diagnosis and Pathogenesis for Medical Diseases and Tumors
Percutaneous and transjugular liver biopsy tests have been utilized for over 50 years for the evaluation of medical liver disease and for the diagnosis of hepatic mass lesions. The increasing use of noninvasive methods for assessing liver fibrosis, coupled with the expanding utilization of direct-acting antiviral medications for the treatment of  chronic HCV hepatitis, has clearly led to a recent decrease in the volume of liver biopsies. Nevertheless, histologic assessment of a liver biopsy specimen remains the gold standard for diagnosis of most medical liver diseases and mass lesions. (Source: Surgical Pathology Clinics)

Pathologic Features of Hereditary Cholestatic Diseases
The inherited diseases causing conjugated hyperbilirubinemia are diverse, with variability in clinical severity, histologic appearance, and time of onset. The liver biopsy appearances can also vary depending on whether the initial presentation is in the neonatal period or later. Although many of the disorders have specific histologic features in fully developed and classic cases, biopsies taken early in the disease course may be nonspecific, showing either cholestatic hepatitis or an obstructive pattern of injury requiring close correlation with the laboratory and clinical findings to reach the correct diagnosis.

Contemporary Topics in Breast Pathology
Breast pathology can be one of the more challenging areas for all involved in diagnostic surgical pathology, and there are several areas of breast pathology that are particularly difficult or problematic. In this Breast Pathology issue of Surgical Pathology Clinics, experts in the field have provided comprehensive reviews of commonly encountered problematic lesions in breast pathology, including fibroepithelial lesions, spindle cell lesions, mucinous lesions, and lobular carcinoma in situ, as well as the less frequently encountered, but nonetheless problematic, phenomenon of lymph node inclusions.

Genotype-Phenotype Correlations in Breast Cancer
Only a few breast cancer histologic subtypes harbor distinct genetic alterations that are associated with a specific morphology (genotype-phenotype correlation). Secretory carcinomas and adenoid cystic carcinomas are each characterized by recurrent translocations, and invasive lobular carcinomas frequently have CDH1 mutations. Solid papillary carcinoma with reverse polarity is a rare breast cancer subtype with a distinctive morphology and recently identified IDH2 mutations. We review the clinical and pathologic features and underlying genetic alterations of those breast cancer subtypes with established genotype-phenotype c...

Processing and Reporting of Breast Specimens in the Neoadjuvant Setting
Standardization of quantification of residual disease in the breast and lymph nodes with routine pathologic macroscopic and microscopic evaluation leads to accurate and reproducible measures of response to neoadjuvant treatment. Multidisciplinary collaboration and correlation of clinical, imaging, gross and microscopic findings is essential. The processing approach to post-neoadjuvant breast cancer surgical specimens and the elements needed in the pathology report are the same regardless of breast cancer subtype or type of neoadjuvant treatment.

Precursor Lesions of the Low-Grade Breast Neoplasia Pathway
The nonobligate precursor lesions columnar cell change/hyperplasia and flat epithelial atypia, atypical ductal hyperplasia and atypical lobular hyperplasia, lobular carcinoma in situ, and low-grade ductal carcinoma in situ share morphologic, immunophenotypic, and molecular features supporting the existence of a low-grade breast neoplasia pathway. The practical implication for pathologists is that the identification of one of these lesions should prompt careful search for others. From a clinical management perspective, however, their designation as “precursor lesions” should not be overemphasized, as the risk of...

Lobular Carcinoma In Situ
Lobular carcinoma in situ (LCIS) is a risk factor and a nonobligate precursor of breast carcinoma. The relative risk of invasive carcinoma after classic LCIS diagnosis is approximately 9 to 10 times that of the general population. Classic LCIS diagnosed on core biopsy with concordant imaging and pathologic findings does not mandate surgical excision, and margin status is not reported. The identification of variant LCIS in a needle core biopsy specimen mandates surgical excision, regardless of radiologic-pathologic concordance. (Source: Surgical Pathology Clinics)

A Diagnostic Approach to Fibroepithelial Breast Lesions
Fibroepithelial breast lesions encompass a heterogeneous group of neoplasms that range from benign to malignant, each exhibiting differing degrees of stromal proliferation in relation to the epithelial compartment. Fibroadenomas are common benign neoplasms that may be treated conservatively. Phyllodes tumors are relatively rare lesions, and classified as benign, borderline, or malignant based on histologic evaluation of various parameters. The diagnostic interpretation of “gray-zone” fibroepithelial lesions often imposes formidable demands on a pathologist’s skills. (Source: Surgical Pathology Clinics)

Problematic Colorectal Polyps
Two issues commonly arise for pathologists reporting adenomatous polyps of the colorectum. Particularly problematic within large sigmoid colonic adenomas is the distinction between benign misplacement of epithelium into the submucosa and invasive malignancy. This distinction requires careful morphologic evaluation of key discriminatory features, assisted only rarely by the application of selected adjunctive immunohistochemistry. Following a diagnosis of adenocarcinoma within a polypectomy or other local excision specimen, systematic assessment is required of features that may indicate the risk of residual local and/or noda...
