Book excerpt: This book comprehensively covers modern soft tissue pathology and includes both tumors and non-neoplastic entities. Soft tissues make up a large bulk of the human body, and they are susceptible to a wide range of diseases. Many soft-tissue tumors are biologically very aggressive, and the chance of them metastasizing to vital organs is quite high. In recent years, the outlook for soft-tissue cancers has brightened dramatically due to the increased accuracy of the pathologist's tools. All methods of diagnosis are covered here, with an emphasis on the newest immunoassays and other genetic, molecular, and immunologic diagnostic modalities. This book's systematic description of benign and malignant primary soft tissue tumors with didactic, comprehensive panels of illustrations allows the reader to formulate a complete understanding of the morphology of tumor entities at one glance. The book covers both the most common tumor entities and more unusual diseases using more than 1,500 color images, making it a resource for beginning and senior pathologists.
