The book is full of high yield tables and figures. I think is useful for the USMLE but only after reading another source like Medical Microbiology and Immunology Examination and Board Review or from Kaplan. It also has many interesting questions at the end of each case. Is a very well organized text; don't think that you're going to see only cases and questions, NOT it begins each case with the basic concepts in that topic, then the case, and detail explanations of the disease, and some questions. If you don't have the time to read the complete text, I think that you can do very well just with the tables and Figures(full color), it contains some MRIs, CT, x-rays, and electron microscopies. Most of the cases are about the most high yield diseases (immunologic diseases) found in the USMLE and some are about diseases that you may have never heard but that may be tested as gene knock-outs or mutations cases. Is useful for USMLE Step 1,2 and 3 since it gives you basic concepts, pathogenesis and explanations about treatment.
