The high-yield, at-a-glance summaries in quick reference format for a variety of issues that pathologists commonly encounter in their everyday practice or on the boards are compiled in this book. The emphasis is on everything else that goes into pathologic diagnoses but is hard to remember, rather than organ-based histologic criteria. The focus is on tumour syndromes, molecular markers, grading schemes, immunohistochemistry, specific stains, and useful clinical references. Morphologic summaries including high-yield content across all organ systems are also given. Examples include an illustrated lexicon of pathologic descriptions, a guide for microorganisms, and a guide for tumour differentials.
