A 12-year-old Japanese boy presented with a 3-month history of a painless nodule on his left ear. There was no history of antecedent trauma or infection. Physical examination revealed a small purple nodule, approximately 8 9 7 mm in diameter, located on the left auricle (Fig. 1a). Dermoscopic observation revealed a purple appearance with dotted or globular vessels. In addition, linear, dendritic vessels crossed the spaces within the lesion, forming complete or incomplete polygons (Fig. 1b). Clinically, we suspected lymphangioma, pseudocyst of the auricle or haemangioma as the preoperative diagnosis. To make a final diagnosis, the lesion was resected under local anaesthesia.
