Vitiligo and psoriasis

J S Koransky, H H Roenigk

    Journal of the American Academy of Dermatology
    |August 1, 1982
    PubMed
    Summary

    Co-occurrence of vitiligo and psoriasis is rare, but a recent cluster of seven cases was observed. Extensive workup did not reveal a clear pathogenetic link between these two autoimmune skin conditions.

    Area of Science:

    • Dermatology
    • Immunology
    • Autoimmune Diseases

    Background:

    • Vitiligo and psoriasis are distinct autoimmune skin conditions.
    • Their co-occurrence in a single patient is historically considered uncommon.
    • Understanding potential links is crucial for patient management.

    Observation:

    • A notable cluster of seven patients with both vitiligo and psoriasis was identified over three years.
    • A literature review found only eighteen previously documented cases.
    • Psoriasis did not predominantly initiate or localize to vitiliginous areas in these patients.

    Findings:

    • No clear predisposition of depigmented skin to psoriasis was observed.
    • While both conditions involve immunologic phenomena, the specific mechanisms are dissimilar.
    • Comprehensive diagnostic workup, including blood tests and biopsies, failed to establish a pathogenetic relationship.

    Implications:

    • The study highlights a potential increase in co-occurrence, warranting further investigation.
    • Current evidence does not support a direct causal link or shared pathogenesis.
    • Further research into shared genetic or environmental factors may be necessary.
