This is a first-ever dermatopathological atlas and diagnostic textbook with over 600 sharply detailed black-and-white photographs of skin histopathology. It contains 36 visual and text-based chapters of differential diagnosis, each listing and illustrating entities with similar diagnostically important architectural and cytologic features. The book features descriptions as well as diagnostic hints alongside each illustration-for easy reading and for self-assessment exercises. The first section covers laboratory methods and the second section illustrates the histopathology of skin diseases by epidermis, dermis, subcutis, and organisms. The book includes bibliographic references and an index. The authors explain this unique volume's clinical and educational value in their preface: "An understanding of dermatopathology is important not only for pathologists, but also for practicing dermatologists. If a histopathologic diagnosis does not 'fit' clinically, the proper diagnosis may often be reached by understanding that some conditions which present rather different clinical appearances may in fact look similar under the microscope."
