Psoriasis is an autoimmune disorder that speeds up the life cycle of the cells and cells start to come to the surface before time.
PSORIASIS IS CHARACTERIZED BY AN ABNORMALLY EXCESSIVE AND RAPID GROWTH OF THE EPIDERMAL LAYER OF THE SKIN.

There are main five types of psoriasis:
# PLAQUE PSORIASIS- also known as psoriasis vulgaris (90% cases) typically presents with red patches with white scales on top. Areas affected- back of forearms, shins, around the navel and the scalp.
# GUTTATE PSORIASIS- has drop shaped lesions and starts in childhood or young adulthood. Triggers may include injury to skin, stress, strep infection or respiratory infection.
# PUSTULAR PSORIASIS- presents with small non-infectious pus filled blisters on palm or feet.
# INVERSE PSORIASIS- forms red patches in skin folds such as the armpits, groin area, and under the breasts.
# ERYTHRODERMIC PSORIASIS- occurs when the rash becomes very widespread and can develop from any of the other type. This is seen after leaving the treatment in which there is fiery red, shedding scales. May be seen after infection or sunburn also.
