Types of psoriasis

Psoriasis is an autoimmune disease, meaning the cells of your immune system have gone rogue. Mistreating and attacking healthy cells in your body as foreign cells.

When your immune system senses foreign invaders, it discharges an army of proteins to attack healthy cells. Escalating the production of skin cells in four to seven days, as opposed to the normal 21 to 28 days.1 Causing new cells to grow way too quickly on the surface of the skin.

The look and feel of psoriasis are flaky skin, scaly skin, red skin, itchy skin, burning skin, patches, and plaques. Psoriasis skin looks thicker and more inflamed compared to other skin conditions.

2 Your dermatologist may perform a biopsy on your skin lesion to examine it more closely. Discover six different types of psoriasis that you need to know before getting them confused with other skin conditions.

Don’t Scratch Your Head! 4 Skin Problems That Resemble Psoriasis

There are many types of skin conditions out there, it can be confusing. To the untrained eye, a patch of scaly skin may look a lot like psoriasis. The real difference lies in the shape of the edges of the affected area, the colour, and the thickness of the scales.

1. Eczema. Also known as atopic dermatitis. It looks very much like psoriasis. Dry, red, flaky skin, but the condition is not contagious. Eczema usually occurs in places where the skin will bend, such as: hands, feet, elbows, or fingers; psoriasis can occur almost anywhere like on your face, scalp or palm.

Children may experience mild itching with psoriasis, but they may experience intense itching with eczema.9 Your dermatologist is able to tell both skin conditions apart based on their trained eye, the amount of itch, and the affected areas.

2. Dandruff. A very common condition. It looks very similar to scalp psoriasis. Both produce skin flakes on the scalp, but their symptoms are different. Dandruff gives you white, oily flakes, 10 whereas psoriasis gives you red patches of inflamed skin, covered with silver-white scales. These scales (or plaques) may be painful. Scratching may cause the skin to bleed. Dandruff is rarely serious and it is easier to treat.

3. Seborrheic dermatitis. A yeast rash that can be confused with scalp psoriasis. It may cause long-term distress. Shares symptoms of psoriasis, such as itchy, scaly, and red skin. Seborrheic dermatitis skin looks swollen and greasy, covered with crusty white or yellowish scales. 11 Skin flakes may attach to the hair shaft. Psoriasis on the other hand, can cross the hairline and extend beyond the scalp.

4. Scabies. A contagious skin condition. Caused by infestation of tiny mites that you can pick up from your bedding, clothes, and furniture. 12 Although scabies can develop anywhere on the skin, these mites prefer to dwell in certain parts of the body, such as: hands, fingertips, arms, elbows, wrists, and skin that is usually covered by clothing or jewellery.13 Scabies can be mistaken for psoriasis due to itchiness, little bumps of rash, scaly patches, or thick crusts on the skin. Avoid direct, skin-to-skin contact with others. It will go away once treated.
