Consult the HEMATOLOGIST is a book that deals with real life cases seen by Pediatric hematologists. I tried to approach the most important hematology cases that can face either the Pediatrician or general practitioner when a further management plan is required. Although this book is aimed primarily at those dealing with hematology patients, I hope that it will be of benefit for those who are studying hematology. Furthermore, the cases in this book can be utilized as discussion materials in teaching programs for medical students. The book is divided into two chapters: Chapter 1 handles the clinical approach to a hematology case from history taking to full examination. Chapter 2 is designed as a consultation form, reply to the consultation, and finally case discussion with various schematic approaches and illustrations.
