Psoriasis is a noncontagious, lifelong skin condition that affects about 2–3% of the population of the United States. People with psoriasis have thickened, red, and often scaly patches on their skin. Psoriasis is very likely to run in families, but it can also be triggered by certain situations, such as emotional stress, injury to the skin, infection, as well as taking certain medications. The exact cause of psoriasis is unknown, but it seems to be caused by errors in how the immune system functions.
A stye (hordeolum) is a local, acutely inflamed growth (swelling, lesion) of the eyelid. They can occur at the lid margin or farther up the lid on either the inner (tarsal) side or the outer (skin) side of the lid. A chalazion is the chronic form of a stye, and its cellular makeup is different than that of a stye.Both the meibomian and sebaceous oil glands of the lid can be involved in this process, which begins with a blockage of the normal openings of these glands, leading to the swelling. Typically, there is bacterial contamination.
Phototherapy uses ultraviolet (UV) light under medical supervision to treat certain skin diseases. Depending on the skin disorder being treated, phototherapy is delivered for several seconds to minutes per session, usually 2–3 times per week. Phototherapy is predominantly an office-based procedure, but home treatment regimens with portable light boxes can also be prescribed to carefully selected patients. Phototherapy can be used alone or in combination with topical or systemic medications, depending on the indications. Common types of UV light treatment include:Broadband UVB light therapy (280–320 nanometer wavelengths) Narrow band UVB light treatments (311 nanometer wavelength only) UVA light therapy (320–400 nanometer wavelengths of light) PUVA (320–400 nanometer wavelengths of light). This is UVA light therapy combined with an oral light-sensitizing medication known as psoralen.
Onychoschizia, commonly known as nail splitting but also known as onychoschisis or lamellar dystrophy, is a condition that causes horizontal splits within the nail plate. Nail splitting is often seen together with onychorrhexis – long-wise (longitudinal) splitting or ridging of the nail plate – and these 2 diseases together are called "brittle nail syndrome." Frequent wetting and drying of the hands is the most common cause of nail splitting, so this condition is, therefore, common among house cleaners, nurses, and hairdressers. Nail splitting may also be caused by nail cosmetics (hardeners, polish, polish removers/solvents), nail procedures, and occupational exposure to various chemicals (alkalis, acids, cement, solvents, thioglycolates, salt, sugar solutions). Injury (trauma) may also play a role in the development of brittle nails. Brittle nails may occur due to medical problems, including gland (endocrine system) diseases, tuberculosis, Sjögren syndrome, and malnutrition. People with other skin diseases, such as lichen planus and psoriasis, as well as people taking oral medications made from vitamin A, may also develop nail splitting.
Nail lifting (onycholysis) is the spontaneous separation (detachment) of the fingernail or toenail from the nail bed at the end of the nail (distal) and/or on the sides of the nail (lateral). The appearance of nail lifting may resemble a half-moon, or the free edge of the nail may rise up like a hood. Nail lifting creates space under the nail that gathers dirt and debris made of protein in the nails (keratin). As water accumulates under the nail, bacteria and yeast can also cause the area to become infected.Nail lifting may occur with other skin conditions, such as various forms of eczema (including hand dermatitis), psoriasis, and lichen planus. Nail lifting may also occur with underlying medical problems, including thyroid disease, pregnancy, some forms of infection, and rarely some forms of cancer. Other possible causes are injury to the nails, use of nail cosmetics, and aggressive manicures.Nail lifting may be caused by some medications, such as chemotherapy and drugs made from vitamin A. Some medications (commonly tetracycline) may interact with sunlight to cause nail lifting.
Blepharitis is inflammation of the eyelids. When it involves the outside front of the eyelid, where the eyelashes are attached, it is called anterior blepharitis. Anterior blepharitis may be caused by: Bacteria Scalp dandruff (seborrheic dermatitis) Allergy Psoriasis If blepharitis involves the inner eyelid, it is called posterior blepharitis. Posterior blepharitis may be caused by:Dysfunction of the oil (meibomian) glands in the eyelid Acne rosacea Scalp dandruff (seborrheic dermatitis)Allergy
Nummular dermatitis is a particular form of eczema (atopic dermatitis) characterized by coin-shaped, raised areas on the skin that are scaly.The cause of nummular dermatitis is not known, but it is associated with triggers such as frequent bathing, irritating and drying soaps, and exposure to irritating fabrics such as wool. Those with nummular dermatitis often have some of the signs and symptoms typically associated with eczema. Nummular dermatitis is itchy (pruritic), but it is less itchy than other common diagnoses with scaly plaques, such as psoriasis. Winter is usually the time of onset and severity. Nummular dermatitis can be chronic, and symptoms can go away and recur indefinitely.
Genentech, Inc. has voluntarily withdrawn the psoriasis drug Raptiva® (efalizumab) from the US market. Raptiva is associated with an increased risk of progressive multifocal leukoencephalopathy (PML). PML is a rare and usually fatal disease of the central nervous system. There are no known interventions that can adequately treat PML. The chief medical officer of Genentech, Hal Barron, MD, believes that Raptiva has helped many psoriasis sufferers, but the risk of PML outweighs the drug’s benefits. Approximately 46,000 patients worldwide have taken Raptiva for chronic plaque psoriasis. There have been 3 cases of diagnosed PML in patients receiving Raptiva. It is not known whether other unreported cases have occurred.
Psoriasis is a chronic scaly skin condition that affects primarily the top layer of the skin, or epidermis. The cause of psoriasis, while not entirely understood, is due in part to an individual's inherited genetic background and its interactions with the immune system and skin cells. Within psoriatic skin, there is an exaggerated immune response, which leads to overproduction, or hyperproliferation, of skin cells in the epidermis. Overactivation of the immune system in psoriasis also leads to inflammation, and together these phenomena are manifested by the thick, red, scaly skin that characterizes psoriasis.
Testimonial from Ron F I was in college the first time I got psoriasis. Since then I’ve had it for many years and have tried many different treatments. Throughout my life, psoriasis was always there as an emotionally troublesome and physically uncomfortable disease.
Psoriasis can be a very upsetting diagnosis, but you should know that you are not alone. Around 7 million people (2-3%) Americans are affected by psoriasis. People with psoriasis have thickened, red, and often scaly patches on their skin. Psoriasis is very likely to run in families, but it can also be triggered by certain situations, such as emotional stress, injury to the skin, infection, as well as taking certain medications. The exact cause of psoriasis is unknown, but it seems to be caused by errors in how the immune system functions. Recently, many celebrities have announced that they are afflicted by psoriasis. From Kim Kardashian to CariDee English (winner of America's Next Top Model in 2006), women famous for their beauty have all of the same treatment options available to them as anyone else.
My Mohs story actually began about 50 years ago when, as a youth, I developed chronic head-to-toe psoriasis. Psoriasis—characterized by thick, red, scaly patches on the skin that sometimes itch—is a life-long condition thought to be caused by a malfunction in the immune system. My psoriasis was extensive, and by adulthood, after getting married and entering the work force, I sought out more aggressive treatments to help manage the disease. At the time, treatment options were limited. Some of the therapies used back then would be considered inappropriate by today’s treatment standards. These treatments put me on a path to skin cell damage that would eventually lead me to my first Mohs surgery, which was 5 years ago.
Famous people are immune from jail time, financial woes, and thanks to graphic designers, bad looking skin. They may look like they have flawless skin, but underneath all those Photoshop layers are some common conditions that can affect anyone.

The National Psoriasis Foundation sponsors Psoriasis Awareness Month each year in August. This skin disorder affects 125 million people worldwide and inflicts both physical and emotional pain on its sufferers. Psoriasis not only affects the skin, but it also affects the overall health of its sufferers. Approximately 10–30% of psoriasis sufferers will experience psoriatic arthritis. Individuals with psoriasis are also at risk of becoming obese and developing cardiovascular diseases.
A balanced diet is crucial for overall health. But do certain foods also have specific benefits for managing psoriasis? Many people with the disease believe so. However, research has yielded mixed results. Here’s what’s known about diet and psoriasis—and what’s not.
