Importance  Daylight photodynamic therapy using topical methyl 5-aminolevulinic acid (MAL) for actinic keratoses (AKs) is as effective as conventional photodynamic therapy but has the advantage of being almost pain free. Daylight photodynamic therapy, however, requires dry and warm weather conditions.

Objective  To establish if topical MAL ...

The incidence of melanoma has been rapidly increasing in the United States. Since exposure to UV radiation from indoor tanning is preventable, reducing exposure is an important strategy for melanoma prevention.1 The article by Lazovich et al2 in this issue of JAMA Dermatology provides an in-depth ...

Epidermolysis bullosa (EB) comprises a clinically heterogeneous group of disorders characterized by fragility of skin, leading to formation of blisters, erosions, and chronic ulcers. The cutaneous manifestations, together with extracutaneous complications, cause considerable morbidity and in some cases premature death.1,2 Epidermolysis bullosa is an orphan ...

Importance  In the United States and Minnesota, melanoma incidence is rising more steeply among women than men younger than 50 years. To our knowledge, no study has examined age- and sex-specific associations between indoor tanning and melanoma to determine if these trends could be due to greater ...

Importance  Rosacea, a common facial skin disorder, has a poorly understood pathogenesis in which increased matrix metalloproteinase activity might play an important role. Glioma accounts for 80% of all primary malignant tumors in the central nervous system, and these tumors also show upregulation of certain matrix metalloproteinases....

Importance  Epidermolysis bullosa (EB) is a group of mechanobullous genodermatoses characterized by the fragility of skin and mucous membranes. Mutations in the ITGA6 and ITGB4 genes, encoding the hemidesmosomal protein α6β4-integrin, have been involved in the pathogenesis of EB. To date, the inheritance ...

Importance  Solid-organ transplant recipients (OTRs) are at an increased risk for skin cancer. Prior studies have demonstrated a reduced incidence of skin cancer in renal OTRs treated with sirolimus. However, little information exists on the use of sirolimus for the prevention of skin cancer in nonrenal OTRs ...
