Psoriasis can have a significant impact on a patient’s Quality of Life, sometimes profoundly altering their everyday life.
TYPES OF PSORIASIS
Plaque Psoriasis (Psoriasis Vulgaris)
It is the most common form of psoriasis. It affects 80 to 90% of people with psoriasis. Plaque psoriasis typically appears as raised areas of inflamed skin covered with silvery white scaly skin. These areas are called plaques.
Appears as raised bumps that are filled with non- infectious pus(pustules). The skin under and surrounding pustules is red and tender. Pustular psoriasis can be localised, commonly to the hands and feet, or generalised with widespread patches occurring randomly on any part of the body.
Produces a variety of change in the appearance of finger and toenails. These changes include discolouring under the nail plate, pitting of the nails, thickening of the skin under the nail, and the loosening(onycholysis) and crumbling of the nail.
It is characterized by numerous small oval (teardrop- shaped) spots. These numerous spots of psoriasis appear over large areas of the body, such as the trunk, limbs, and scalp. Guttate psoriasis is associated with streptococcal throat infection.
Flexural Psoriasis (Inverse Psoriasis)
Appears as smooth inflamed patches of skin. It occurs in skin folds, particularly around the genitals (between the thigh and groin), the armpits, under an overweight stomach (pannus), and under the breasts (inframammary fold). It is aggravated by frication and sweat and is vulnerable to fungal infections.
Involves the widespread inflammation and exfoliation of the skin over most of the body surface. It may be accompanied by severe itching, swelling and pain. It is often the result of an exacerbation of unstable plaque psoriasis, particularly following the abrupt withdrawal of systemic treatment. This form of psoriasis can be fatal, as the extreme inflammation and exfoliation disrupt the body’s ability to regulate temperature and for the skin to perform barrier functions.
