List of 100 Different Skin Conditions
Below is a list of 100 distinct skin conditions compiled from dermatological resources. These are drawn from comprehensive databases like DermNet, the American Academy of Dermatology (AAD), and Wikipedia’s dermatology listings. For each condition, I’ve included a brief description and a reliable source link where you can view photos (typically clinical images from medical sites like DermNet or AAD). These sites provide high-quality, educational images for reference—please note that viewing medical photos may be graphic, and consulting a dermatologist is recommended for any personal concerns.
