**3.1 Menzies method**

The Menzies technique is an improved dermoscopy strategy for diagnosing melanomas [40, 41]. In the first arrangement, it had an affectability of 92% and a specificity of 71% for the analysis of melanoma. This strategy utilizes purported "negative" and "positive" highlights. For a melanoma to be analyzed, none of the two "negative highlights" ought to be found and no less than 1 of the 9 "positive highlights" must be available. An injury is suspicious of melanoma on the off chance that it has in excess of one shading and is hilter kilter in design. Suspect lesions showing any of the nine positive highlights for melanoma are thought to be melanoma except if demonstrated something else.
