A fully illustrated diagnostic guide for the trainee and practising haematologist. The authors take the traditional approach to diagnosis - morphological abnormalities of blood cells - and combine this with typical clinical appearances. Examples of both are given for each condition discussed, and the reader is then guided through to further appropriate investigations such as histology, radiology and computed tomography. The basic science underlying conditions such as thalassaemia is explained using specially concieved, full-colour diagrams.
