Pathology is an inherently subjective discipline, and therefore is often referred to as both an art and a science. Over the years, laboratory physicians have implemented special tissue stains and molecular techniques to limit subjectivity in the discipline. Beginning in the late 19th century, histochemical stains were developed to assess diagnostic biochemical reactions in tissue. Histochemistry has recently seen a resurgence in popularity because of the higher costs of other newer methods. Today, this technique is used by almost every pathology laboratory across the world. This book comprehensively covers all diseases for which that technique plays a central role in diagnosis. Every anatomic region is covered in detail with examples of appropriate staining techniques, and the book is heavily illustrated with over 850 color photomicrographs. This is the first monograph to be published on histochemistry in 15 years, and it is the only one that is diagnostically-oriented.
