Very graphic but interesting site with numerous photographs of various skin diseases. From Lupus, Scleroderma, eczema, Vitilogo, thrush, warts, cancer, cold sores, ulcers and etc. If you have a weak stomach pass on this link.

Personally, I cringed and shrank but I looked on with fascination and also kindness for those in the pictures.
