3. New Heights: Dermatoscopy: Introduction of a new algorithmic method based on pattern analysis for diagnosis of pigmented skin lesions
Harald Kittler, M.D.
Dermatoscopy has become a widely used technique for diagnosis of pigmented lesions of the skin. Beginners in dermatoscopy often are confused by the lack of precise, repeatable criteria and opaque terminology.
To analyze conventional nomenclature of dermatoscopy and to create a system based on terms defined clearly.
Review of conventional nomenclature in dermatoscopy and of numerous dermatoscopic images of lesions in the skin.
Conventional descriptions of structures observed by dermatoscopy employ images that do not correspond to those in the brain of most viewers. A new algorithmic method based on patterns created by simple geometric elements is suggested.
The new method suggested here is utilizable for every morphologic aspect of dermatoscopy. It should facilitate application of dermatoscopy and enhance capability for teaching it.
