There are many different types of skin��disease�and it takes�years of experience and study to understand these.  This is why dermatology trainees have at least 5 years of post graduate study to become a specialist dermatologist.   The practice of dermatology is based on a visual approach with an appreciation of recurrent patterns and images. This applies from clinicopathologic differential diagnoses to the orientation of transposition flaps in the surgical settings.  Dermatology includes all aspects of��skin surgery and is based on a sound understanding of��cutaneous and surgical principles.  Dermatologists who specilise in are known as dermatologic surgeons.
