Facing psoriasis and atopic dermatitis: are there more similarities or more differences?

Area of Science:

• Dermatology
• Immunology
• Genetics

Background:

• Atopic dermatitis (AD) and psoriasis vulgaris (Pso) are frequent chronic inflammatory skin diseases.
• Historically, AD and Pso were considered to have distinct underlying mechanisms.
• Recent advancements have deepened the understanding of their complex pathologies.

Purpose of the Study:

• To provide an overview of current knowledge on atopic dermatitis and psoriasis vulgaris.
• To explore the similarities and differences between AD and Pso based on recent findings.

Main Methods:

• Review of recent genetic, epidemiologic, and pathophysiologic findings for AD and Pso.
• Comparative analysis of the two conditions.

Main Results:

• Emerging evidence highlights shared and distinct factors in the pathogenesis of AD and Pso.
• Genetic, epidemiologic, and pathophysiologic data offer new insights into disease mechanisms.

Conclusions:

• The understanding of atopic dermatitis and psoriasis vulgaris is evolving.
• Further research into the similarities and differences between AD and Pso is warranted.
