PSORIASIS
PSORIASIS
grouped Papulosquamous
eruptionIdiopathic, chronicIt is caused by
thickening of the epidermis layer.
PSORIASIS
Approximately 30% of patients have a family history of the same disease. believed
to be inherited as Multifactorial inheritance
PSORIASIS
Abnormalities in arachidonic acid metabolism and abnormal cell immunity of the
skin Epidermis cells multiply abnormally Dividing cells from the basal layer
PSORIASIS
It takes 3-4 days to reach the epidermis (usually 4 weeks). Cells lack normal
cohesion, causing keratin to easily peel off. Cell granular layer disappears. inserted
into the Keratin layer
PSORIASIS
There are many types of lesions.1. Chronic plaque type psoriasis is a thick, red,
flaky patch or white scale attached to it, rising, collapsing, found in the area of
friction. including head and nails
PSORIASIS
There are many types of lesions.2. Guttate psoriasis is a small nodule that occurs
all over the body, often following streptococci infection in the throat.
PSORIASIS
There are many types of lesions.3. Flexural psoriasis is found in soft areas with red
patches and found in folds. Must be separated from fungi.
PSORIASIS
There are many types of lesions.4. Palmoplantar psoriasis Dry, thick, scaly rash
difficult to distinguish from Chronix eczeme.
PSORIASIS
The nail is pitted (nail pitting), the nail is rough (Nail dystrophy), the nail is hard
from the skin. (Onycholysis) thickening of the skin under the nail (subunpual
keratosis).
Psoriasis is a chronic, multifactorial skin condition characterized by papulosquamous eruptions caused by abnormalities in arachidonic acid metabolism and skin cell immunity. It is believed to have a genetic component and results in various types of lesions like chronic plaque, guttate, flexural, and palmoplantar psoriasis. Additionally, nail abnormalities such as pitting, dystrophy, onycholysis, and subungual keratosis are common in psoriasis patients.
