Lallas K, Arceu M, Martinez G, et al. - This study was intended to distinguish dermoscopic predictors associated with benignity and malignancy in tumors characterized by a predominant dermoscopic presence of blue color. Researchers retrospectively analyzed the institutional database for tumors exhibiting blue color in at least 50% of their surface with available histopathologic diagnosis. Fifty-three were benign (35 blue nevi, 10 angiomas, and 8 seborrheic keratoses) and 38 malignant (12 melanomas and 26 basal cell carcinomas) out of 91 included tumors. According to the findings, in predominantly blue tumors, the probability of malignancy is high when blue color is seen in clods or is asymmetrically distributed and when gray color or linear vessels coexist. This study’s findings demonstrate that a diffuse distribution of blue color, its expansion in more than 75% of the surface, and the absence of vessels are highly suggestive of a benign tumor.
