Phototherapy for atopic dermatitis.

Phototherapy is a second-line treatment for moderate to severe atopic dermatitis (AD) that effectively decreases cutaneous inflammation with minimal or no systemic side effects. Children in grade school, adolescents, and adults may benefit from phototherapy, when they have chronic AD refractory to first-line topical treatments. This review focuses on six approaches for phototherapy in AD: (1) broadband ultraviolet B (UVB), (2) Goeckerman regimen (coal tar + broadband UVB), (3) narrowband UVB, (4) excimer lasers for targeted areas, (5) combination UVA/UVB, and (6) UVA-1.

Early Recognition of Proteus Syndrome.

Proteus syndrome is an extremely rare mosaic condition characterized by progressive overgrowth of tissues due to a somatic activating mutation of the AKT1 gene. Distinct cutaneous features, including cerebriform connective tissue nevi, epidermal nevi, vascular malformations, and adipose abnormalities, can alert the dermatologist to the underlying condition before the onset of asymmetric skeletal overgrowth. We present a series of photographs documenting the skin and musculoskeletal changes in a patient with Proteus syndrome over the first 2 years of life to emphasize the key signs that a dermatologist can recognize to facilitate an earlier diagnosis in these patients.
