Superficial Melanocytic Pathology

Add Expert Analysis of Difficult Cases to Your Practice With Consultant Pathology Superficial Melanocytic Pathology provides expert guidance for resolving the real world problems pathologists face when diagnosing melanomas and other atypical pigmented lesions. It reviews each major category of atypical melanocytic lesions, including the pathology of the superficial categories of melanoma followed by a discussion of the major simulants of melanoma. The book provides an overview of the morphologic description and diagnostic issues for each lesion, followed by 60 detailed, abundantly illustrated case presentations, offering an expert approach to diagnosis for a range of challenging cases. Five hundred high-quality color images support the case presentations. Of special interest is a chapter on "ambiguous" lesions of uncertain significance. The book's thorough analysis of challenging lesions will aid pathologists in differentiating between benign superficial proliferations and malignant melanocytic tumors. All Consultant Pathology Titles Provide: ACTUAL consultation cases and expert analysis EXPERT analysis provides a detailed discussion of the reasoning behind the diagnosis of each case COMPREHENSIVE coverage of challenging diagnoses CASES that are richly illustrated with high-quality photomicrographs

Melanocytic neoplasms are of capital importance for all surgical pathologists and dermatopathologists. These tumors span a huge range of morphologic expression and biologic behavior, are potentially of the highest medical significance and are often fraught with diagnostic pitfalls and high litigation risk. Pathology of Challenging Melanocytic Neoplasms offers a dynamic text where readers will encounter a broad spectrum of challenging melanocytic lesions, both benign and malignant and will thereby acquire a solid, working knowledge that they can immediately apply to daily diagnosis. The authors aim to clarify this often thorny field, keeping a steady focus on patient-related issues. The volume emphasizes the practical application of basic morphologic principles, immunohistochemistry and molecular methods in order to secure a confident diagnosis. Abundant illustrations display the characteristic features of the most important disease entities. Rather than being yet another encyclopedic work of reference, this volume takes a fresh approach as it resembles a series of stimulating seminars employing exemplary case material to highlight, illustrate, and succinctly discuss the key points. To this end, the reader will be guided through a series of paired cases that pose a significant diagnostic challenge. By comprehensively comparing and contrasting two related entities, each such chapter will illuminate an intellectual pathway through which an important diagnostic puzzle can be solved. To broaden the differential diagnosis even further, additional illustrative cases are added to each discussion. Algorithms and tables summarize key points. Clinically relevant, up-to-date references will be provided to guide further study. Written by experts in the field, this novel text will be of great value to surgical pathologists in practice and dermatologists as well as residents and fellows training in these specialties.

This book offers a practical approach to the histologic analysis of a wide range of melanocytic skin lesions, including various nevi and different forms of melanoma, as well as pigmented non-melanocytic lesions. In addition, sentinel node biopsy findings and the use of special ancillary studies are covered in detail. Each chapter presents illustrative cases that document the route to correct diagnosis. An important feature of the book is the clinical-pathologic correlation of challenging melanocytic tumors; accordingly, it will appeal not only to pathologists (general surgical pathologists and dermatopathologists) but also to dermatologists (including dermatopathologists). The book contains some 250 color photos as well as tables and algorithms designed to assist in the diagnosis of difficult cases.​

In surgical pathology practice, distinguishing malignant from benign melanocytic lesions represents one of the major problem areas. Failure to diagnose a malignant melanoma can have catastrophic results, but separating melanomas from their simulants is often difficult, and over-diagnosis of melanoma is also inappropriate. This edition presents a comprehensive account of benign and malignant melanocytic lesions. The benign lesions encompass the major simulants of melanoma. In addition, some of them, such as dysplastic nevi, have significance as markers of individuals at increased risk for the development of melanoma. It has become ever more apparent, especially with the recent advent of molecular classification, that melanoma is not one disease, and that prognosis in melanoma can vary considerably from lesions that present minimal risk, to dangerous malignancies at opposite ends of a spectrum. The details of therapy for these lesions are very different and are determined for the most part by their diagnostic and prognostic features as judged by microscopy. This edition explains in detail the use of attributes for microstaging and for prediction of prognosis in melanoma, including discussion of the latest AJCC staging system. More importantly, however, it provides a richly-illustrated roadmap for diagnosis of the entire spectrum of melanocytic tumours. Discussion of the lesions is firmly grounded in their clinical significance, with detailed descriptions of clinical features often accompanied by clinical images. Lesions in general are illustrated in multiple microscopic images ranging from scanning magnification to high power. Cytologic as well as architectural features are clearly delineated. Pathophysiology, epidemiology, and molecular attributes are also discussed. This work will serve as a comprehensive text for learning on the part of trainees, and also as an invaluable diagnostic reference for more experienced diagnosticians in daily practice.
