The Margin Masterclass: Atlas of Practical Mohs Histopathology
Mohs Micrographic Surgery is a highly specialized dermatological procedure where the surgeon acts as their own pathologist, rapidly examining horizontally frozen sections of tissue to ensure 100% of the cancer margin is clear while sparing maximum healthy skin. Reading these specific slides—often fraught with freezing artifacts and confusing tangential cuts—is a unique and demanding skill. Atlas of Practical Mohs Histopathology is the definitive, fiercely practical visual manual designed specifically for the Mohs laboratory. This volume provides the exact blueprints required by surgeons to confidently trace out aggressive skin cancers on frozen sections in real-time.
Mastering the Horizontal Section
The core philosophy of this text is adapting to the unique Mohs perspective. Traditional pathology looks at tissue vertically (like slicing a loaf of bread); Mohs looks at tissue horizontally (like looking down into a bowl). The authors aggressively detail how this perspective alters the appearance of normal adnexal structures (hair follicles, sweat glands), dictating exactly how to avoid confusing a benign hair bulb with an invasive nest of basal cell carcinoma.
Navigating Artifacts and Aggressive Subtypes
The book provides a masterclass in frozen section interpretation. It dictates the exact clinical pathways for identifying high-risk, infiltrative, and morpheaform variants of basal cell and squamous cell carcinomas, which often send invisible microscopic roots far beyond the clinical margin. It provides exhaustive, high-yield imagery of common freezing artifacts (ice crystals, crush artifact, folding) and explains how to “read through” them to find the tumor.
Frequently Asked Questions (FAQs)
Does this book cover Mohs for melanoma?
Yes, it includes specialized chapters on the use of rapid immunohistochemistry (like MART-1) during Mohs surgery to trace the subtle, insidious margins of lentigo maligna.
Who is the primary audience?
It is the absolute, mandatory visual atlas for Mohs Surgeons, Dermatopathologists, Dermatology Residents, and Mohs Histotechnicians.
