Examples of psoriasis
A-J display appearances of psoriasis lesions on typical areas of
the skin. Lesions can be present on any area of the body. D is
an example of minimal psoriasis. 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."
