This book contains a compilation of highly relevant, concise summaries in a quick-reference format on various topics that pathologists frequently encounter in daily practice or during examinations. The focus is not on organ-based histological criteria, but rather on everything else that plays a role in pathological diagnoses and is difficult to remember. Emphasis is placed on immunohistochemistry, special stains, assessment systems, molecular markers, tumor syndromes, and helpful clinical references. Additionally, it includes morphological summaries that cover highly relevant material from all organ systems, such as an illustrated guide to microorganisms, tumor differential diagnoses, and an illustrated glossary of pathological terms. The book features a unique format, as the information is primarily presented in tables and diagrams, accompanied by short and concise explanatory texts.
