Understand the distinct features of plaque, guttate, inverse, nail, pustular, and erythrodermic psoriasis. Learn when to seek medical advice for proper diagnosis and management of this chronic skin condition.

Psoriasis is a long-lasting skin condition characterized by inflamed, scaly patches that often itch. These patches commonly appear on the knees, elbows, back, and scalp, with symptoms fluctuating over cycles of flare-ups and remission. While the precise cause isn't fully understood, immune system imbalance is considered a key factor.

Major Psoriasis Variants

Several forms of psoriasis exist, each with unique features and clinical signs.

1. Plaque Psoriasis

Known as psoriasis vulgaris, this type results in rapid skin cell turnover, forming thick, silvery plaques mainly on elbows, knees, scalp, and back. Symptoms may include raised discolored patches, cracking, bleeding, and intense itching. Triggers such as stress, dry skin, certain foods, sun exposure, or skin injuries can provoke outbreaks.

2. Guttate Psoriasis

This form predominantly affects young adults and often follows infections like strep throat. It manifests as small, pink or red tear-shaped or round patches ranging from 2 to 10 mm, mainly on the torso, legs, and arms. It may cause ongoing itching and discomfort.

3. Inverse Psoriasis

Inverse psoriasis occurs in skin folds such as armpits, groin, beneath the breasts, and around the navel. Friction, sweating, and fungal infections can trigger it. Symptoms include shiny, smooth, discolored patches that might crack, ooze, or become tender. Infections can lead to pus-filled bumps and bad odor.

4. Nail Psoriasis

Nail involvement affects the area under the nails, often accompanying other psoriasis types, especially in individuals over 40. Signs include yellow or brown discoloration, nail pitting, ridges, brittleness, peeling, and sometimes fungal infections.

5. Pustular Psoriasis

This variant features scaly patches with pustules filled with fluid, affecting areas like the face, scalp, hands, and feet. Generalized pustular psoriasis may cause fever and muscle weakness, while localized forms may involve bumps, cracks, swelling, and tenderness. Subtypes include Palmoplantar and Acrodermatitis.

6. Erythrodermic Psoriasis

This rare and severe form causes widespread redness, scaling, and peeling of the skin, often with fever, dehydration, pain, and swelling. It usually occurs when psoriasis is uncontrolled and requires urgent medical care.

Common symptoms across types include thick, red, itchy, burning skin with silvery scales, cracked skin, nail changes, and sleep issues. Proper diagnosis by healthcare professionals is essential, as symptoms can vary significantly.
