Surgical Pathology Differential Diagnosis Playbook

When two lesions look alike, the diagnosis depends on knowing what separates them. Surgical pathology is rarely about recognizing one isolated image. The difficult cases are the ones in which several entities share overlapping morphology, clinical features, or immunophenotypes. The challenge is knowing where to start, what to compare, which findings matter most, and when ancillary testing will actually resolve the differential. Surgical Pathology Differential Diagnosis Playbook provides a practical, pattern-based approach to solving these problems at the microscope and during sign-out. Instead of presenting pathology as a long list of diseases to memorize, this guide organizes diagnostic reasoning around the patterns and problems that pathologists encounter in practice. Inside, you will learn how to: - Recognize the dominant histologic pattern and build a focused differential diagnosis - Distinguish morphologically similar tumors, tumor mimics, and reactive processes - Use diagnostic algorithms to move from pattern recognition to a defensible diagnosis - Compare competing diagnoses using high-yield morphologic features - Select and interpret immunohistochemistry as part of a rational diagnostic workup - Recognize common diagnostic pitfalls and misleading findings - Approach difficult cases using a structured case-based reasoning framework - Apply practical grossing principles that support accurate microscopic diagnosis - Review high-yield diagnostic pearls useful for residency training, sign-out, and examination preparation Designed for pathology residents and practicing surgical pathologists Whether you are learning surgical pathology during residency, preparing for pathology examinations, reviewing a difficult case at sign-out, or looking for a practical bench-side…
