TL;DR: A guide for pathologic evaluation of PDAC specimens with the macroscopic and microscopic features of common PDAC and its variants is provided and the differential diagnosis and morphologic and immunophenotypical prognostic parameters are discussed.

TL;DR: This article presents an overview of the diagnostic categories of benign and malignant nerve sheath tumors, including neuroma, neurofibroma, nerve she Heath myxoma, perineurioma, schwannoma, andmalignant peripheral nerveSheath tumor.

TL;DR: Information is presented on the pathology of spindle cell sarcomas in terms of an overview of the tumor, microscopic and gross features, diagnostic techniques, genetic markers, differential diagnosis, clinical details, and prognosis.

TL;DR: Benign tumors, although histologically less diverse, are far more common, with pleomorphic adenoma and Warthin tumor the most common salivary gland tumors.

TL;DR: Proliferative verrucous leukoplakia, an unusual clinical disease, mimics oral lichen planus clinically and requires careful correlation of the clinical and pathologic features.

TL;DR: This review describes the clinicopathologic characteristics, differential diagnosis, and biologic behavior of exocrine pancreatic tumors of predominantly nonductal differentiation: acinar cell carcinoma, pancreatoblastoma, and solid-pseudopapillary neoplasm.

TL;DR: Variants of oral and oropharyngeal SCC are discussed and those features that help distinguish human papillomavirus-related from human papillsomav virus-unrelated S CC are highlighted.

TL;DR: Pancreatic intraepithelial neoplasias are the most common of the pancreatic cancer precursor lesions, yet they remain poorly understood and are so small that they are almost clinically undetectable.

TL;DR: Immunohistochemical stains for p53, p16, ER, PR, mib-1, hepatocyte nuclear factor 1β and pan-cytokeratin can be helpful in classifying high-grade carcinomas but should be used in concert with thorough morphologic examination, as part of a rational panel of markers and only in specific circumstances.

TL;DR: The molecular pathogenesis of certain tumors, such as mucoepidermoid carcinoma and adenoid cystic carcinoma, has recently begun to be elucidated.

TL;DR: This review presents a discussion of the gross and microscopic features, diagnosis, differential diagnosis, and prognosis of neoplastic lesions of the cervix.

TL;DR: In this review, ovarian metastatic carcinomas from various sites, as well as other neoplasms secondarily involving the ovary, are discussed and the value of immunohistochemistry in distinguishing between primary and metastatic neoplasm in the Ovary is discussed.

TL;DR: The authors address a group of loosely associated, characteristically benign soft tissue neoplasms that exhibit partial myoid differentiation and attempt to clarify the distinct architectural patterns and the corresponding immunophenotypic and ultrastructural features that distinguish myofibroma, myopericytoma, myoepithelioma, and my ofibroblastoma.

TL;DR: This review addresses typical and atypical pathologic features of Pan-NETs, with a focus on practical issues involved in differential diagnosis, immunohistochemical work-up, intraoperative frozen section interpretation, sources of diagnostic errors, and classification.

TL;DR: This review covers the group of relatively uncommon nonserous ovarian epithelial tumors, focusing on the group's distinctiveness from the much more common serous tumors and showing the similarities across entities.

TL;DR: Evidence-based histologic criteria for atypical endometrial hyperplasia and low grade endometrian carcinoma (both FIGO grade 1 and 2) are presented with emphasis on common and not so common histologic mimics.

TL;DR: As tumors with primitive round cell morphology are seen in virtually every basic tumor category, the diagnosis of small round cell neoplasms requires the use of ancillary diagnostic techniques: immunohistochemistry and often molecular genetics.

TL;DR: The most commonly encountered pancreatic lesions and the importance of correlation of cytologic features with clinical, radiologic, and ancillary studies for accurate diagnosis are focused on.

TL;DR: This article presents an overview of soft tissue tumors that have a plexiform histomorphology, including the more commonly encountered entities, and information on clinical features, microscopic findings, ancillary studies, differential diagnosis, and prognosis is provided.

TL;DR: The sinonasal tract (SNT) includes the nasal cavity and paranasal sinuses and may give rise to a variety of nonneoplastic and neoplastic proliferations, including benign and malignant neoplasms.

TL;DR: Metastatic clear cell tumors, including renal cell carcinoma and adrenal cortical carcinoma, should be considered in the differential diagnosis and excluded through clinical history, imaging studies, and immunohistochemical stains.

TL;DR: The key features of pelvic SC, current concepts of its pathogenesis, histopathological diagnostic criteria, discuss differential diagnosis, and review diagnostic ancillary studies that can be used in practice are reviewed.

TL;DR: Carcinoma of the vulva is an uncommon malignant neoplasm and represents 4% of all genital cancers in women, and squamous cell carcinoma is the most common histologic type.

TL;DR: Characteristics of disorders such as chronic, autoimmune, eosinophilic, hereditary, and infectious pancreatitis are described to convey an appreciation of these disorders because their recognition can benefit patients tremendously, as inflammatory lesions of the pancreas can be mass-forming, giving rise to pseudotumors, and leading to surgical resection that may otherwise be unnecessary.

TL;DR: The clinical, radiographic, and pathologic features of tumors and tumorlike lesions affecting the bones of the head and neck region, particularly those that occur with more frequency or those that are unique to this part of the skeleton are described.

TL;DR: The authors present an overview of the disease and discussions of genetic predisposition, prevention, screening, and diagnosis of ovarian, fallopian tube and primary peritoneal carcinomas as well as surgical and chemotherapeutic techniques for the various stages of disease.

TL;DR: This content presents a review of molecular pathology of ovarian cancer, and presents key molecular features for high-grade and low-grade serous carcinomas, endometrioid carcinomes, clear cell carcinoma, and mucinous carcinomas.

TL;DR: The clinicopathologic characteristics and differential features of pancreatic mucinous tumors are presented, which appear important to distinguish them from other cystic neoplasms and non-neoplastic cysts.

TL;DR: This review focuses on recent advances in the area ofLow-grade ovarian serous neoplasia with emphasis on key diagnostic criteria, differential diagnosis, and disease classification based on current understanding of low-grade serous carcinogenesis.
