We’ll show you a non-exclusive selection of some common skin conditions with the characteristics you have chosen: a dark blue box indicates a diagnosis is COMMON, light blue indicates it's UNCOMMON, and grey indicates a diagnosis is RARE.
Click on IMAGE box for examples of the condition. To find out more about the condition, click on the BLUE box. To review the clinical features selected, click on the GREY boxes above the algorithm or click here to return to the previous option or click here to use the DermDiag tool again.
