The interpretation of melanocytic tumors represents probably the most difficult task in the field of dermatopathology. The second edition of this text and atlas depicts a broad range of the most important and most challenging melanocytic lesions. Each individual case is illustrated with at least three high-quality color photographs and is commented on at length, highlighting the diagnostic clues. The goal of the authors is to assist the ordinary pathologist in making a precise workable diagnosis in their daily practice. They achieve this by providing simple criteria that will serve as a sound basis for an unequivocal diagnosis of either a benign or a malignant melanocytic neoplasm. The reader will find Histological Diagnosis of Nevi and Melanoma to be an invaluable guide to correct diagnosis even in difficult or rare cases.
