The lesion, which was firm and measured 15?mm in diameter, was papulonodular, dome-shaped, and erythematous-violaceous in color (Fig. 1A). Figure 1. A, Firm erythematous-violaceous, papulonodular lesion on the external aspect of the left arm. B, Dermoscopic image showing whitish structures on an erythematous base, nonarborizing telangiectasias, vessels with a glomerular appearance, and a slight brown reticular pattern mainly on the periphery. What Is Your Diagnosis? Arteriovenous tumor.
