This book provides an authoritative guide to the histological and genetic typing of human tumors of the skin. This volume covers keratinocytic, melanocytic, appendageal, haematopoietic, soft tissue and neural tumors, as well as inherited tumor syndromes. Each tumor is introduced with a concise definition and discussion of nomenclature, followed by a summary of what is known about its incidence, age and sex distribution, location, clinical signs and symptoms, pathological features, associated genetic alterations, and predictive factors. Distinctive features are further characterized through the inclusion of over 600 color photographs and numerous MRIs, CT scans, and charts showing genetic alterations. The classification uses ICD-O codes from the third edition.
