The incidence of Psoriasis is slightly greater in patients with existing Vitiligo.
There is a rare tendency for psoriasis to start in areas of vitiligo. Additionally, it is noted that psoriasis sometimes starts at and remains in areas of depigmented skin. Also, there is a resistance of vitiligo in dark skinned psoriasis patients.
Science has not yet discovered the cause of the immunologic phenomena of vitiligo and psoriasis. Thus far there has been no understanding of the relationship of the two diseases.
Psoriasis is dissimilar to Vitiligo in almost every aspect except that they are both skin diseases. Psoriasis produces dry, scaly, itching skin that is primarily genetically predisposed. It may be an autoimmune condition. It may be a trigger that causes a proliferation of normal skin cells to overproduce.
Normal skin cells will proliferate or turn over in about 21-18 days. With psoriasis the turn around is 2-6 days. 3% of the population suffers from Psoriasis and affects people between ages of about 10 through 50. It is not a contagious condition.
Patients with psoriasis suffer from the stigma of unsightly, and sometimes large patches of ominous looking skin lesions.
Unlike Vitiligo, psoriasis includes the constant shedding of dead skin cells that accumulate in thick patches, usually on the anterior legs, elbows and abdomen. The scaly, crusty patches shed readily. It is also common on the scalp with severe itching and a burning sensation.
Psoriasis, like Vitiligo, can sometimes have a trigger. An infection, certain types of over-the-counter medications or prescription medications can trigger the condition. Stress and skin lesions also have a tendency to trigger psoriasis in patient with a predisposition.
Vitiligo is markedly different than Psoriasis. It is a loss of melanocytic cells - those responsible for pigmentation of the skin. Localized vitiligo is characterized by small isolated patches of depigmented skin, also referred to as "focal" vitiligo. Or in medical terminology "Vitiligo Segmentalis".
Generalized Vitiligo is a more pervasive form of the disease involving several lesions in many areas of the body. Also called "Vitiligo Vulgaris". Heredity is at the top of the list of risk factors; however, there are numerous cases of individuals with no known familial predisposition. An autoimmune disease, vitiligo is not, otherwise, understood. Other factors for risk include: genetic predisposition, autoimmunity, neurogenic, and environmental factors.
A primary care physician often makes the diagnosis and/or a dermatologist and it is usually based on typical clinical features. Often an ultraviolet device is used to identify areas of depigmentation, especially in lighter-skinned patients. In some cases the diagnosis is confirmed by skin biopsy.
While there are some cross similarities in Vitiligo and Psoriasis, science has not yet found a link that will give promising information leading to a cure. Many of the recommended treatments for Vitiligo offer some relief or, at least, can help to arrest the condition.
