[Morphology and morphogenesis of psoriasis].

V G Shlopov, T I Shevchenko

    Summary

    Psoriasis involves systemic connective tissue and blood vessel damage, leading to microcirculatory vasculitis. This damage disrupts basement membranes, causing excessive skin cell growth and altering cell interactions in psoriasis patients.

    Area of Science:

    • Dermatology
    • Pathology
    • Immunology

    Context:

    • Psoriasis is a chronic inflammatory skin condition.
    • The underlying pathobiology of psoriasis remains incompletely understood.
    • Previous research has focused on epidermal changes.

    Purpose:

    • To investigate the systemic morphologic changes in connective tissue and vessel walls in psoriatic patients.
    • To elucidate the relationship between microcirculatory vasculitis and epidermal proliferation in psoriasis.

    Summary:

    • Postmortem examinations of 7 psoriatic patients revealed systemic progressive involvement of connective tissue and vessel walls.
    • Proliferative and destructive vasculitis in the microcirculation was identified as a key feature.
    • Damage to basement membranes and connective tissue disorganization compromised collagen-mediated regulation of epithelium-mesenchyme interactions, driving excessive epidermal proliferation.

    Impact:

    • This study highlights systemic vascular involvement as a core feature of psoriasis.
    • Findings suggest that targeting microcirculatory inflammation and connective tissue integrity may offer novel therapeutic strategies.
    • Understanding these mechanisms provides insights into the complex interplay between the immune system, vasculature, and skin in psoriasis.
