Split-face comparison between single-band and dual-band pulsed light technology for treatment of photodamage.

Background: Intense pulsed light (IPL) has a well-recognized role in the treatment of photodamaged skin.

Objective: To assess the safety and efficacy of a novel single-band IPL handpiece versus dual-band IPL handpiece in the treatment of photodamage.

Study Design/materials And Methods: This was a prospective, single-center split-face study with 20 enrolled participants.

Plasmacytoid (CD68+CD123+) monocytes may play a crucial role in the pathogenesis of hydroa vacciniforme: a case report.

Hydroa vacciniforme (HV) is a rare, blistering, childhood photodermatosis that heals with smallpox-like scars, is associated with latent Epstein-Barr virus (EBV) infection, and spontaneously resolves by early adulthood. Cytotoxic T cells are suspected to mediate the histologic hallmark of HV-dense, perivascular, lymphocytic infiltrates and reticular degeneration and necrosis of the epidermis. We report a case of 13-year-old white girl with EBV-associated HV, whose lesional skin harbored a predominate CD68, CD123 infiltrate of plasmacytoid monocytes (PMs).
