LWBK713-FM-i-xvi.qxd 7/23/10 7:55 PM Page v Aptara I would like to dedicate this book to my mother, Lottie Dudek, who was born on November 11, 1918. Through the years my mother raised her children, maintained a loving marriage, and worked 40 hours per week. In the year 2004, society would describe such a person as a “liberated woman” or “supermom.” I would like to acknowledge that my mother was a “supermom” 20 years before the word was fashionable. A son cannot repay a mother. My hope is that “I love you and thank you” will suffice. v LWBK713-FM-i-xvi.qxd 7/23/10 7:55 PM Page vi Aptara LWBK713-FM-i-xvi.qxd 7/23/10 7:55 PM Page vii Aptara Preface High-Yield Histopathology does more than just review histology. The questions on the USMLE Step 1 cross traditional course boundaries, making it difficult to identify a question that is “strictly histology.” Many USMLE Step 1 questions fall into the categories such as histopatholo- gy, histophysiology, histomicrobiology, and histopharmacology. To write a review book on basic, traditional histology would not be helpful to the student preparing for the USMLE Step 1 since there are no basic traditional histology questions on the exam. In this regard, High-Yield Histopathology reviews important histology concepts as a gateway to the pathology, physiology, microbiology, and pharmacology of clinically relevant topics. In addition, many students have commented that cell biology topics have been well represented on the USMLE Step 1. To this end, I have included Chapter 1 (Nucleus), Chapter 2 (Cytoplasm and Organelles), and Chapter 3 (Cell Membrane) with up-to-date and clinically relevant informa- tion. I would appreciate any comments or suggestions concerning High-Yield Histopathology, espe- cially after you have taken the USMLE Step 1 exam, that you think might improve the book.
