A new study supports speculation that exposure to low level laser therapy may stimulate proliferation of melanoma cells.

The Merkel cell polyomavirus (MCPyV), first identified in rare aggressive Merkel cell carcinoma in 2008, has now been isolated in up to a third of patients with squamous cell carcinoma (SCC), according to a new study published online in the Journal of Investigative Dermatology.

World report — Darker-skinned patients with morphea and related diseases are as likely to benefit from ultraviolet (UV) light therapy as patients with lighter skin.

Human skin cells exposed to the ozone in smog exhibit changes in signaling pathways that put them at increased risk for developing cancer.

Patients with the highest quintile levels of the active form of vitamin D (>30 ng/ml) in the blood had a 40 percent reduced risk of skin cancers compared with those in the lowest quintile (<16 ng/ml), according to a recent study.

Ceftaroline is a new beta-lactam cephalosporin that shows potent activity against MRSA in vitro and in human trials.

The enzyme DGAT1 is a crucial regulator of retinoic acid, which affects weight and is important to healthy skin and hair, according to researchers.
