980-nm laser diode and treatment of subcutaneous mass in Proteus-like syndrome.

tological findings are different from our results. We had no evidence for other inflammatory skin diseases following Blaschko’s lines such as linear discoid lupus erythematosus or lichen striatus. Linear pigmentary disorders such as pigmentary mosaicism (naevoid hypermelanosis) or the pigmentary stage of incontinentia pigmenti were also excluded. The aetio-pathogeny of LAM remains unknown, but its Blaschko-linear pattern suggests mosaicism for a hitherto unidentified mutation.
