This book reviews normal thymic structure and covers the histomorphology of benign and malignant tumors and rare lesions of the thymus, with detailed descriptions of over 300 full color photomicrographs accompanied by relevant clinical and radiology photographs and anatomical drawings. It includes chapters on the surgical pathology and cytology of thymic lesions (which is rarely described in the available literature), and all grades and stages of the most common thymic lesions. Written and edited by leading experts on pathology, the book highlights the expanded role of pathologists in patient care for thymic lesions. It will help students to understand thymic cytology and surgical pathology in detail and enable them to answer questions on thymic surgical resections and cytology cases in their pathology post-graduation examination. In addition, the book offers a comprehensive, richly illustrated guide to thymic pathology for clinicians, practicing pathologists, post-graduate residents and students alike.
