More than 700 photographs highlight both the classic diagnostic features as well as many of the variations. Each disease article includes photos such as the ones shown below for the primary lesions of psoriasis. Move the mouse cursor over any photo and click to enlarge it. You can then click on the enlarged photo to return back to the photo set.

Within each article there are often additional sets of photographs listed at the top left of the page. Clicking on an item such as "Primary lesions", "Patient A" or "Patient B" will display that set of photos.
