The cause of psoriasis is related to the immune system, and more specifically, a type of white blood cell called a T lymphocyte or T cell. Normally, T cells travel throughout the body to detect and fight off foreign substances, such as viruses or bacteria. If you have psoriasis, however, the T cells attack healthy skin cells by mistake as if to heal a wound or to fight an infection.

K-M are examples of psoriasis affecting fingernails. Although psoriasis-affected toenails can look very similar to this, people with athlete's foot may have similar-appearing toenails; therefore it is better to judge psoriasis by fingernail appearance alone. K and L display nail pits. M shows characteristic yellowish or brown color known as an "oil spot.“
