Brief Answer:
Palmar psoriasis
Detailed Answer:
Hello and welcome to healthcaremagic
I am Dr. Kakkar. I have gone through your query and I have understood it.
Psoriasis is an inflammatory skin disease characterised by well defined erythematous scaly plaques with silvery white or candle wax type of scaling. Chronic
plaque psoriasis is the most common type. It can affect sites like scalp, arms, and legs, (specifically elbows and knees), palms and soles etc Other types of psoriasis are:
Erythrodermic psoriasis,
Pustular psoriasis (generalised and localised), Nail psoriasis and Scalp psoriasis.
Diet has no direct role ,whatsoever i psoriasis. There are no studies which recommend to include a particular type of diet in psoriasis OR vice versa.
However, diet has an indirect role to play in patients with psoriasis in term of its association with other diseases. Psoriasis is associated with
metabolic syndrome and its components like obesity, diabetes and hypertension/coronary artery disease/myocardial infraction. Obesity has been shown to be an independent risk factor for the development of psoriasis, and obesity is also associated with more
severe psoriasis.
Therefore diet restrictions which are otherwise recommended in patients with diabetes, coronary artery disease/hypertension, obesity hold all the more importance in patients with psoriasis as well.
Coming to your second question of psoriasis localized to your hands: Since psoriasis of the palms and soles mostly presents with scaly erythematous plaques, therefore, if I was your treating doctor I would have asked you to apply a good moisturizer as frequently as possible. Moisturizers hydrate as well as form an occlusive film thereby preventing further loss of moisture from the skin.
Moisturizers specially those which contain hygroscopic (attract water from the atmosphere and lock it into the skin) and keratoloytic agents like
Ammonium lactate, Urea, Lactic acid etc are especially useful in dry scaly conditions like psoriasis.
Moisturizers should be applied as frequently as possible.
For the patches you could use a steroid+salicylic acid ointment, twice daily (clobetasol+3% OR 6% salicylic acid in an ointment base) over and above the moisturizer for 4 weeks.
Other treatment modalities which can be used for localized palmar psoriasis are: Vit D analogues like calcipotriol, calcipotriene alone or in combination with steroid.
Once weekly oral methotrexate is another option in case of palmar psoriasis but it should always be taken under the supervision of a
dermatologist since it can rarely cause serious side effects like bone marrow suppression.
I hope you will find this information useful
