This is the second edition of an important practical manual for hematologists, pediatric oncologists, and pathologists. It is intended to help practitioners interpret pediatric blood films, bone marrows, and lymph-node touch preparations, and particularly with regard to the importantdifferences between age groups. The book focuses on the most frequently encountered cases, however those requiring more complex tests are also included. The new edition has been substantially revised and includes many new figures and an improved layout for greater ease of use.
