Hypopigmentation 1 — Foundations & the Failure Map | Rook's Ch 68 | Dermatology, the Rook's Way

Why skin loses colour: melanocytes that never arrive, melanin that can't be made, and melanosomes that can't mature or move. The one failure map that organises every hypopigmentation disorder in Rook's Chapter 68 (Genetic Disorders of Pigmentation) — piebaldism, Waardenburg, albinism, Hermansky–Pudlak, Chédiak–Higashi, Griscelli and the mosaic disorders. Dermatology, the Rook's Way — Rook's Textbook of Dermatology taught the visual way: diagram-first lectures for dermatology residents and students, every topic from the basics. 📌 New lectures weekly. Exam-level MCQ video for this chapter is on the channel — answers are revealed one week later. #dermatology #RooksTextbook #FCPS
