Summary of "A case of lichen aureus successfully treated with 595 nm wavelength pulsed-dye laser."

Lichen aureus (LA) is a variant of pigmented purpuric dermatosis (PPDs) that typically presents with the acute onset of a solitary, unilateral, purple to rust-yellow colored lichenoid patch or plaque on lower extremities. Treatment remains challenging and is based on anecdotal case reports often with poor results.

Medical and Biotech [MESH] Definitions

Penetrating electromagnetic radiation emitted when the inner orbital electrons of an atom are excited and release radiant energy. X-ray wavelengths range from 1 pm to 10 nm. Hard X-rays are the higher energy, shorter wavelength X-rays. Soft x-rays or Grenz rays are less energetic and longer in wavelength. The short wavelength end of the X-ray spectrum overlaps the GAMMA RAYS wavelength range. The distinction between gamma rays and X-rays is based on their radiation source.

Tunable liquid lasers with organic compounds (i.e., dye) which have a strong absorption band, used as the active medium. During emission, the dye has to be optically excited by another light source (e.g., another laser or flash lamp). The range of the emission wavelength may be anywhere from the ultraviolet to the near infrared (i.e., from 180 to 1100nm). These lasers are operated in continuous wave and pulsed modes. (UMDNS, 2005)

Atrophy and shriveling of the SKIN of the VULVA that is characterized by the whitish LICHEN SCLEROSUS appearance, inflammation, and PRURITUS.

A strain of Staphylococcus aureus that is non-susceptible to the action of METHICILLIN. The mechanism of resistance usually involves modification of normal or the presence of acquired PENICILLIN BINDING PROTEINS.

A chronic inflammatory mucocutaneous disease usually affecting the female genitalia (VULVAR LICHEN SCLEROSUS) and BALANITIS XEROTICA OBLITERANS in males. It is also called white spot disease and Csillag's disease.
