📖 Built from Real Diagnostic Practice

PATH Notes was born out of necessity during pathology residency. Day after day, the same essential concepts kept coming up—practical criteria, diagnostic clues, and key details that are difficult to retain and not always easy to find quickly in large textbooks.

What started as a personal collection of quick-reference notes gradually evolved into a structured and cohesive resource. Over time, it became clear that these were not just isolated reminders, but a core set of tools used continuously in routine diagnostic work.

This book compiles those high-yield notes into a single, accessible format—designed to be practical, concise, and easy to use. It doesn’t replace comprehensive textbooks; instead, it complements them by giving you a fast, reliable reference exactly when you need it.
