This book will be a full-color atlas of both benign and neoplastic proliferations in the blood. The book will illustrate the morphologic features on peripheral blood smears of the various disorders and the text will focus on diagnostic criteria, differential diagnosis and modern classification terminology. The book may be used as a stand-alone resource and should be useful to trainees and clinicians that routinely review peripheral blood smears. The book will be accompanied by an on-line image bank containing numerous additional full-color images of the various disorders.
