Description
Description
100 Rare Tumors of the Digestive System: A Case-Based Reference for Surgical Pathologists provides practicing surgical pathologists, gastroenterologists, oncologists, and surgeons with a comprehensive review on the clinical and pathologic features of rarely encountered neoplasms in the digestive system. The book uses a case-based format to cover typical clinical settings, including clinical history, symptoms, laboratory and radiographic findings, and representative histologic and immunologic pictures. This is the perfect reference for clinicians that would like to know more about updated terminology, histopathologic presentation, potential pathogenesis mechanisms, and treatment strategies for digestive disease entities.
Scientists and researchers can also reference this book to find disease entities of interest, including pathogenesis, immunophenotype, and molecular findings. Multiple choice questioning is provided for readers to decide on the best diagnosis from a list of mimickers.

Xiaoyan Liao
Dr. Liao has a background in medicine, basic sciences, and pathology. As a surgical pathologist, she specializes in gastrointestinal, liver and pancreatobiliary pathology dealing with challenging cases in daily practice, interacting with clinicians for case diagnosis, and writing peer-reviewed case reports published in Pathology journals. Dr. Liao is also a passionate teacher, educator, and consultant, devoted to inspiring residents and fellows in surgical pathology. As a scientist, she focuses her research in the molecular pathogenesis associated with gastrointestinal carcinoma, carcinogenesis in patient population of inflammatory bowel disease, appendiceal mucinous neoplasms, lymphoma, and tumor staging for hepatobiliary carcinomas. She is particularly interested in the genetics and signaling pathways involved in digestive system tumors and the correlation with clinical behavior, which are important not only for understanding cancer biology, but also guiding clinical management, prognosis, and targeted therapy.
