Chapter Summary

Scope and Approach

This is the sixth edition of a large reference, about 1,350 pages, that looks at normal human histology from the point of view of the anatomic pathologist. It is written by anatomic pathologists for anatomic pathologists, and the edition is newly edited by Rhonda K. Yantiss, whom Stacey E. Mills chose to continue the book's tradition. Its stated purpose, handed down from Stephen S. Sternberg's original conception and restated by Mills, is that normal does not change while our perception of normal keeps expanding, and that new variations of normal continue to be recognised which cause diagnostic confusion and touch on the interface between normal and disease. The book therefore bridges the gap between textbooks of normal histology and the pathological alterations that a diagnostician must recognise.

Normal Variation

A distinctive focus of the book is variations of the norm related to factors such as age, sex and race, which conventional histology textbooks often leave unclarified. For a pathologist this is the baseline question: whether an unusual appearance is a normal variant or a sign of disease.

Normal Features That Mimic Disease

The book emphasises normal histology and those normal features that may be confused with pathological conditions. It also discusses, briefly, pre-pathological conditions, and pathological processes that are themselves confused with normal tissue. The approach is therefore a two-way boundary: normal tissue that looks abnormal, and abnormal tissue that looks normal.

Illustration and Techniques

The edition features almost 2,000 new and updated gross and microscopic images, including immunohistochemical stains and special stains. It reflects recent advances in immunohistochemical and molecular techniques that give insights into pathological processes, together with a wider awareness of the spectrum of normal findings. New information on surgical principles and techniques has also been added.

Contributors

The edition draws on the knowledge and fresh perspectives of many new authors in addition to its new editor. This reflects the multi-author character of a reference of this size.

Key Concepts

Topic Areas Named in the Book's Scope

• Normal histology from a pathologist's viewpoint: tissue described as the diagnostician needs to know it.
• Normal variation: differences related to age, sex and race.
• Mimics of disease: normal features that can be mistaken for pathology.
• The interface between normal and disease: pre-pathological conditions and pathological processes that can be mistaken for normal.
• Immunohistochemical and special stains: used in the images to show tissue characteristics.
• Surgical principles and techniques: new information added in this edition.

Critical Analysis

Strengths

• A specific purpose. The book does not try to replace a basic histology text. It concentrates on the boundary between normal and abnormal, which is the question diagnostic pathology turns on.
• Attention to variation. Dealing explicitly with age, sex and race helps readers avoid overcalling normal findings as disease.
• Image-rich. Almost 2,000 illustrations, including immunohistochemical and special stains, make it practical as a visual reference at the microscope.
• Written for its audience. Authors who are anatomic pathologists address readers who are anatomic pathologists or in training, so the content is selected for diagnostic relevance.

Limitations

• Not a first course. The book is written for anatomic pathologists and those in training, and its treatment of normal tissue is built around diagnostic questions, so it is not designed as a first histology text.
• Size. With about 1,350 pages, it is a reference to be consulted by organ or topic, not read through.
• Pathology discussed only briefly. Pre-pathological and pathological conditions are covered briefly, so a diagnostic pathology reference is needed for the diseases themselves.

Where It Fits in the Course

In the histology and embryology course, Mills's is the reference to use after the introductory books. Junqueira's Basic Histology: Text and Atlas is a mid-length text and atlas that can be read within a single course, and Wheater's Functional Histology pairs micrographs with concise explanations of function. Ross and Pawlina's Histology: A Text and Atlas combines microscopy, cell biology and clinical correlations. Any of these is the right place to learn normal histology before turning to Mills. Larsen's Human Embryology and Torchia and Persaud's Before We Are Born cover the developmental side of the course and are not substitutes.

Mills answers a different question from those books: not what normal tissue looks like in general, but what a pathologist must know about normal tissue in order to avoid diagnostic errors.

How to Use This Book

It suits pathology residents and trainees, senior medical students considering pathology, biomedical scientists in diagnostic histopathology, and researchers who must interpret human tissue sections. A basic histology course and an introduction to pathology make the book much easier to use.

A practical plan:

• Use it as a lookup reference. When a specimen from a particular organ raises a question, read the corresponding section to learn the normal range and its mimics.
• Read about variation before diagnosing. Check the effects of age, sex and race on the appearance of the tissue before calling a finding abnormal.
• Compare normal with abnormal. Use the images, including those with immunohistochemical and special stains, alongside your own slides.
• Combine with a disease reference. Keep a pathology text beside it for the diagnoses that follow once a change has been judged abnormal.
• Check the edition. The sixth edition has a new editor, many new authors and updated information on techniques, so older editions are not a perfect substitute.
