The introduction of dermoscopy into the clinical practice of dermatology has disclosed a new and fascinating morphologic dimension of pigmented skin lesions (PSL). Dermoscopy is a non-invasive, simple, and inexpensive diagnostic technique that permits the visualization of morphologic features that are not visible to the naked eye, thus forming a link between macroscopic clinical dermatology and microscopic dermatopathology. This sub-macroscopic observation of PSL enriches the available clinical diagnostic tools by providing new morphologic criteria for the differentiation of melanoma from other melanocytic and non-melanocytic PSL.

The seven-point checklist is a simplified dermoscopic algorithm based on pattern analysis that has been proven to be useful for the diagnosis of clinically doubtful melanocytic skin lesions. This checklist provides a simplification of standard pattern analysis because of the lower number of features to identify and the scoring diagnostic system. Thus, it can be easily learned and easily applied and has proven to be reliable in diagnosing early melanoma.
