Dermoscopic vascular pattern may be essential for the correct diagnosis of completely amelanotic melanomas, which are still a diagnostic challenge because of the lack of pigmentation. Here we illustrate the dermoscopy images of 3 biopsy-proven amelanotic melanomas, all Clark level IV and Breslow depth greater than 4 mm, belonging to different patients (Figures 1, 2, and 3). Milky red globules and/or areas (black arrows) and irregular linear vessels (white arrows) were always detected; hairpin (white arrowheads) and dotted vessels (black arrowheads) were observed in 2 cases; and highly tortuous vessels, a rarely described feature, were found in only 1 case (stars in Figure 1). In conclusion, the milky red globules and/or areas, which correspond to highly vascularized tumor cell nests, together with the irregular linear vessels seem to be the most useful dermoscopic features for the . . .
