A number of different skin tumors may exhibit a prominent vascular component and/or ulceration that renders the diagnostic differentiation more difficult to perform. The lesions shown in Figure 1 and Figure 2 were located on the arm (A), shoulder (B), back (C), and thigh (D) of a 46-year-old man, an 11-year-old boy, a 15-year-old girl, and a 26-year-old woman, respectively. Dermoscopic examination of these lesions (Figure 2) revealed red-blue lacunas in all cases (A-D), blue-white veil (A and B), whitish areas of fibrosis (A, B, and D), and a form of arborizing vessels (A). Histopathologic examination revealed a glomangioma, an angiomatoid dermatofibroma, a pyogenic granuloma, and a cherry angioma in the lesions shown in panels A, B, C, and D, respectively, of Figure 1 and Figure 2.
