Each volume in this richly illustrated series, sponsored by the Papanicolaou Society of Cytopathology, provides an organ-based approach to the cytological and histological diagnosis of small tissue samples. Benign, pre-malignant and malignant entities are presented in a well-organized and standardized format, with high-resolution color photomicrographs, tables, tabulated specific morphologic criteria and appropriate ancillary testing algorithms. Example vignettes allow the reader to assimilate the diagnostic principles in a case-based format. This volume describes the cytologic, small core biopsy, immunohistochemical and molecular diagnostic features of musculoskeletal lesions. It provides the cytopathologist and histopathologist with a comprehensive survey of diagnostic approaches and diagnostic features for benign and malignant lesions. Each chapter contains a detailed summary of differential diagnostic features, supported by high-quality images and case studies. The print edition includes a CD-ROM offering all images in a downloadable format. With over 500 photomicrographs, this is an important resource for practising pathologists and residents in pathology.
