About the Book

Pathologic: Volume 1 – Immunology is the first installment of the Pathologic series — a project built to make medical learning clear, visual, and deeply engaging. This volume takes readers through the foundations of immunology, explaining complex mechanisms in a way that’s simple, structured, and clinically relevant.

Designed for both MBBS students and USMLE Step 1 aspirants, this book transforms dense immunological concepts into digestible, visually rich lessons that build true understanding rather than rote memorization.

Pathologic is not just a book — it’s the beginning of a journey. Future volumes will explore systemic pathology and other major subjects, each crafted with the same goal: to make medicine easier to learn and harder to forget. Alongside the books, free lecture materials and visual resources will also be released, expanding the learning experience beyond the page.

About the Author

Muhammad Hassan Karim

Muhammad Hassan Karim is a medical student at Bolan Medical College, currently pursuing his studies with a deep passion for understanding and simplifying the human body.

His journey into medical education began with a realization — that learning medicine should be about balance. Balance between studying and living, between detail and clarity, between memorization and true understanding. Through Pathologic, he aims to bring that balance into how students learn — making complex subjects accessible, enjoyable, and clinically meaningful.

Still a student himself, Hassan draws from his own experiences, frustrations, and breakthroughs to create material that speaks to learners at every level. His goal is simple: to help others see medicine not as a burden, but as a fascinating, evolving story of life — one worth exploring deeply and joyfully.
