Psoriasis is a common, chronic, and recurrent inflammatory disease of the skin characterized by round, reddish, dry scaley patches covered by grayish-white or silvery-white scales. According to the National Psoriasis Foundation, there must be a combination of certain genes and external triggers such as stress, medication, or injury for someone to develop psoriasis. In addition, the skin cells grow at a very fast rate, which causes the buildup of psoriasis lesions.

Lesions are most commonly found on the nails, scalp, elbows, shins, and feet. In the foot, psoriasis can be difficult to distinguish from Athlete's Foot, or the nail appearance may be confused with fungal infections of the toenails.

Plaque psoriasis is the most common type and it appears as described above, however, there are other types of psoriasis that affect the body in different ways.

Psoriasis can cause a characteristic pitting appearance on the nails. Pustular psoriasis is a form of the disease characterized by small pustules or blisters filled with clear or cloudy fluid.

Psoriasis can affect the joints of the feet and lower extremities, leading to painful arthritis.

Treatments of psoriasis include oral medications, light therapy, laser therapy, and topicals.
