Abstract
To date, is yet to be elucidated whether the body location of cutaneous melanoma can significantly affect an early dermoscopic diagnosis and, consequently, if it can be regarded as a prognostic factor. To investigate the dermoscopic appearance of early melanomas (EMs) at different body sites; to test the ability of dermoscopists in recognizing specific dermoscopic features in EMs. A pool of 106 experienced dermoscopists evaluated the presence of 10 dermoscopic features assumed as suggestive of malignancy among 268 images of EMs with ambiguous appearance located at 16 body sites. According to 720 evaluations, EMs of the “upper extremities” showed a prevalence of early atypical lentiginous features. EMs of the “anterior trunk” exhibited the lower rate of recognition for all features. EMs of the “rear trunk” can be regarded as an intermediate area, showing high recognition rates of regression-related and chronic-traumatism-related features.
