Subtypes of Psoriasis

Psoriasis is a chronic autoimmune disease that affects the skin, nails, and joints. There are several subtypes of psoriasis, each with its own unique characteristics and symptoms. In this article, we'll discuss the different subtypes of psoriasis, their causes, and treatment options.

1. Plaque Psoriasis:

Plaque psoriasis is the most common subtype, accounting for about 80% of all cases. It is characterized by raised, red, and scaly patches on the skin. These patches can vary in size and may appear anywhere on the body, including the scalp, elbows, knees, and lower back. Plaque psoriasis is thought to be caused by an immune system malfunction that causes skin cells to grow too quickly.

Treatment options: Topical ointments, phototherapy, systemic medications like methotrexate or biological drugs like adalimumab, etanercept, and infliximab.

2. Guttate Psoriasis:

Guttate psoriasis is a subtype that is more common in children and young adults. It is characterized by small, red, and scaly spots that appear on the limbs, trunk, and scalp. It is thought to be triggered by a streptococcal infection.

Treatment options: Topical steroids, phototherapy, systemic medications like methotrexate or biological drugs like adalimumab, etanercept, and infliximab.

3. Inverse Psoriasis:

Inverse psoriasis is a subtype that affects the skin folds, such as the armpits, groin, and under the breasts. The affected areas are red, smooth, and shiny, with little or no scaling. Inverse psoriasis is thought to be caused by friction and sweating in skin folds.

Treatment options: Topical steroids, calcineurin inhibitors, systemic medications like methotrexate or biological drugs like adalimumab, etanercept, and infliximab.

4. Pustular Psoriasis:

Pustular psoriasis is a subtype that is characterized by white, pus-filled blisters surrounded by red skin. The blisters can appear on the palms of the hands and soles of the feet or all over the body. Pustular psoriasis can be triggered by medications, infections, stress, or exposure to chemicals.

Treatment options: Topical steroids, phototherapy, systemic medications like methotrexate or biological drugs like adalimumab, etanercept, and infliximab.

5. Erythrodermic Psoriasis:

Erythrodermic psoriasis is a severe subtype that affects the entire body. The skin becomes bright red and itchy, and sheds in sheets. Erythrodermic psoriasis is usually triggered by an infection, medication, or other stressors.

Treatment options: Hospitalization, topical ointments, systemic medications like methotrexate or biological drugs like adalimumab, etanercept, and infliximab.

Conclusion:

In conclusion, there are several subtypes of psoriasis, each with its own unique characteristics and treatment options. Treatment options vary depending on the severity of the condition, age of the patient, and the subtype of psoriasis. If you suspect that you may have psoriasis, it's best to consult with a dermatologist for proper diagnosis and treatment.
