Abstract: Dermoscopy is useful for evaluating the precise vascular structure. We recently applied dermoscopy to infantile hemangiomas without proliferation and showed polymorphous vascular structures. We now demonstrate two typical dermoscopic figures of proliferative infantile hemangiomas. One was a superficial hemangioma which showed polymorphous vascular structure without obvious red linear vessels and red dilated vessels. The other was a thicker hemangioma with a deeper component. This hemangioma had polymorphous vascular structures with red linear and red dilated vessels. These observations indicates the usefulness of dermoscopy for subclassifying infantile hemangioma.
