- Abstract
Dear Editor, The aim of our study was to assess the sensitivity of the three-point[1] and seven-point[2] checklist diagnostic algorithms, and the relative frequencies of some dermoscopic criteria and of the "light brown structureless areas", in melanoma I in situ i (MIS) and in invasive superficial spreading melanomas (SSM). In the MIS group, using the three-point checklist gave a positive result in 23 of the 32 lesions, with a sensitivity of 72%, whereas using the seven-point checklist gave a positive result in 25 patients, with a sensitivity of 78%. In our study, structureless light brown areas turned out to be the dermoscopic finding that occurs mostly in the MIS group; in this group they occur with a 75% relative frequency compared with a 32% relative frequency in the invasive SSM group, indicating a statistically significant difference between the two groups ( = 0-001).
