I have noticed for the last 6-8 months that my toenails have become brown in color. They do not hurt, peel, or bother me in any way, but as the new nail grows in, the brown is still there. I have a very bad case of psoriasis on my scalp. Can this be the cause of the discoloration on my toenails? I do not take any medication for the psoriasis other than regular visits to my dermatologist for a steroid shot on my scalp. Do you believe that discoloration is a type of fungus and what can I do to get rid of it?

Ivar Roth, DPM: Psoriasis usually shows up as a pitting of the nail and, over time, it causes nails to thicken. it is normally not associated with a brown color. in my experience, the most common cause of a brown discoloration of the nails is a fungus, but psoriasis can occur as an overlay at the same time.

My current favorite over-the-counter topical solution for treating nail fungus is Nail Cure, which should be applied on the nails two to four times a day. please be aware that it will not work through nail polish. When using this product, results are seen in as little as three months, but can take up to six to nine months to treat an extreme case of toenail fungus. Nail Cure can be purchases through Justlin Medical (Woodinville, Wash.) at (800) 343-7786.
