This text is intended to serve as a practical guide to muscle pathology, particularly for histopathologists and for those in training. In this edition, the authors have taken account of advances in classification and in histological techniques, as well as new knowledge of neuromuscular diseases that have emerged since the first edition was published in 1984. The book should continue to be of value as a practical guide in the diagnosis and understanding of these disorders, and should be available in every hospital histopathology laboratory in which muscle biopsies are examined. This book should be of interest to muscle pathologists, general histopathologists and trainees.
