Designed to appeal to a wide readership including post-registration trainees in internal medicine and haematology, senior medical students and even established physicians, this colour review covers the whole field of malignant and non-malignant haematology, including coagulation problems and infectious diseases, in an attractive and thought-provoking way, for examination revision and for continuing education. It offers a wide range of clinical cases in their microscopic and macroscopic appearances, in random order, of varying lengths and at varying degrees of difficulty.
