There are no references because the information has been collected over the years piecemeal from notes, lectures, journals, textbooks, personal communications with other physicians and experience. You may disagree with some of it. Take it simply for what it is: information that I have found useful in my day to day practice as a clinical dermatologist and my hope is that you find it useful as well.
