When a patient presents to a clinician, it is vitally important for that doctor to be able to differentiate quickly and correctly between the various diseases to which the presenting symptoms may be attributed. Arranged alphabetically, and based upon presenting symptoms, the text takes the reader through a step-by-step approach to that presentation, culminating in a description of the different diagnoses that it might represent. Where instrumental in aiding a correct diagnosis, full colour illustrations of the highest quality have been included.
