Through discussion of some 150-200 lineage-unrelated cutaneous neoplastic disorders (primary and secondary), the reader will become familiar with common and sometimes uncommon but clinically relevant conditions. Each chapter adopts a consistent style for quick and easy reading, covering typical microscopic features, clinical vignettes, histological variations, diagnostic pitfalls and differentials, and key diagnostic pearls. Chapters also explain general pathological principles, laboratory processing of specimens and medico-legal aspects of neoplastic dermatopathology. Each copy of the book is packaged with a password, providing online access to all text and images. Written by leading pathologists and educators, this is an essential resource for trainees and more experienced pathologists tackling the daily sign-out as well as board exams in dermatopathology.
