The third edition of Histologic Diagnosis of Inflammatory Skin Diseases: An Algorithmic Method Based on Pattern Analysis is enhanced exponentially by the integration of print and electronic media. The work is composed of 11 chapters, 9 of which are housed in the printed volume. Chapters 10 and 11, namely, Inflammatory Diseases and Simulators of Inflammatory Diseases, are ensconced exclusively on Derm101.com, but the nine chapters that constitute the book also are available online. The book provides a user with a series of web links that serve as bridges between the print and the electronic product. The bridges lead to all of the inflammatory diseases and simulators of them that are constituents of Interactive Quizzes, the Lecture Library, A Clinical Atlas of 101 Common Skin Diseases, four volumes of Differential Diagnosis in Dermatopathology, three volumes of Clues to Diagnosis in Dermatopathology, and two volumes of Resolving Quandaries in Dermatopathology, each of those subjects in those volumes having been edited newly, extensively, and profoundly.
