2016 Arte Poster Competition First Place Winner: Circadian Rhythm and UV-Induced Skin Damage: An In Vivo Study.

Exposure of the skin to ultraviolet (UV) irradiation causes many detrimental effects through mechanisms related to oxidative stress and DNA damage. Excessive oxidative stress can cause apoptosis and cellular dysfunction of epidermal cells leading to cellular senescence and connective tissue degradation. Direct and indirect damage to DNA predisposes the skin to cancer formation.

Concomitant mycosis fungoides and vitiligo: how mycosis fungoides may contribute to melanocyte destruction.

Background: Few reports have described vitiligo developing in patients with cutaneous T-cell lymphoma (CTCL).

Objective: We sought to identify possible factors that might predispose patients with CTCL to vitiligo.

Methods: Patient demographics, CTCL disease characteristics and treatments were analyzed in 25 patients with CTCL who developed vitiligo.
