A more substantive complaint is that the book is in dire need of an update: it was published in 1993. For example, the sections on lymphoma classifications and HIV treatment are hopelessly outdated. Along the same lines, the questions at the end of each section and the comprehensive exam at the end don't reflect the current USMLE testing style. For one thing, about 70% of the questions in this book are phrased negatively, as in "all of the following are true, EXCEPT...". For another, many of the questions are quite a bit pickier than my experience with the USMLE step 1 (three days ago).
The book also contains far too few photomicrographs, and those are all black and white, but this can be remedied easily with supplemental materials.
