Rules for publishing

Note: The rules for publishing data from dermoscopy photographs have changed (as of Feb 2009). To publish retrospective studies using images from patients you need the following two requisites:

1. You have obtained verbal or written consent (depending upon the rules of your Institutional Review Board (IRB) or Ethics Committee (EC) for the use of the images that “were taken during routine patient care”.

2. One of the following:

A. You have an IRB or EC that has allowed the use of these images in studies – OR –

B. You have an IRB/EC waiver for the use of the images – OR –

C. Your country does not require IRB/EC review for such a collection of images (if you are in this last category, you will need to name the countries in the Methods section).

All participants are encouraged to contact their IRB/EC to confirm what their requirements are.
