Key clinical point: Patients with atopic dermatitis (AD) have a significantly increased risk of developing lymphoma.
Major finding: Patients with AD vs control individuals showed a significantly increased likelihood of developing noncutaneous T-cell lymphoma (odds ratio [OR] 2.52; 95% CI 1.37-4.62), with similar outcomes for the peripheral T-cell lymphoma subtype (OR 4.00; 95% CI 1.50-10.66).
Study details: Findings are from a nested case-control study including 6425 adult patients with AD and 25,700 matched control individuals without AD from electronic health records.
Disclosures: This study did not receive any funding. Benjamin Ungar reported being an employee of Mount Sinai and receiving research funds from and serving as a consultant for various organizations.
