[The use of lasers in medicine with special reference to dermatology]. 1985

G Fürnsinn

The laser machine and the unique quality of the laser beam are described. The basis of the medical application of laser is its capacity to concentrate large amounts of energy on a small volume of tissue, mostly resulting in thermal coagulation necrosis. The effect of monochromate laser radiation varies, depending on the different absorption of various laser beams by tissues. Indications of various types of lasers for treatment, especially in dermatology, are discussed and safety instructions are mentioned.

UI	MeSH Term	Description	Entries
D007627	Keloid	A sharply elevated, irregularly shaped, progressively enlarging scar resulting from formation of excessive amounts of collagen in the dermis during connective tissue repair. It is differentiated from a hypertrophic scar (CICATRIX, HYPERTROPHIC) in that the former does not spread to surrounding tissues.	Keloids
D007834	Lasers	An optical source that emits photons in a coherent beam. Light Amplification by Stimulated Emission of Radiation (LASER) is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation. Lasers operate in the infrared, visible, ultraviolet, or X-ray regions of the spectrum.

D007871	Leg Ulcer	Ulceration of the skin and underlying structures of the lower extremity. About 90% of the cases are due to venous insufficiency (VARICOSE ULCER), 5% to arterial disease, and the remaining 5% to other causes.	Leg Ulcers,Ulcer, Leg,Ulcers, Leg
D009508	Nevus, Pigmented	A nevus containing melanin. The term is usually restricted to nevocytic nevi (round or oval collections of melanin-containing nevus cells occurring at the dermoepidermal junction of the skin or in the dermis proper) or moles, but may be applied to other pigmented nevi.

D001913	Bowen's Disease	A persistent progressive non-elevated red scaly or crusted plaque which is due to an intradermal carcinoma and is potentially malignant. Atypical squamous cells proliferate through the whole thickness of the epidermis. The lesions may occur anywhere on the skin surface or on mucosal surfaces. The cause most frequently found is trivalent arsenic compounds. Freezing, cauterization or diathermy coagulation is often effective.

D002280	Carcinoma, Basal Cell	A malignant skin neoplasm that seldom metastasizes but has potentialities for local invasion and destruction. Clinically it is divided into types: nodular, cicatricial, morphaic, and erythematoid (pagetoid). They develop on hair-bearing skin, most commonly on sun-exposed areas. Approximately 85% are found on the head and neck area and the remaining 15% on the trunk and limbs.
