Ear hemangioma

Hemangioma is a proliferative disease of vascular endothelial cells, encompassing benign tumors, borderline tumors, and malignant tumors. Hemangiomas occurring in the ear are referred to as ear hemangiomas. Most ear hemangiomas are benign tumors, varying in size from small localized lesions to extensive hemangiomas involving the entire auricle, appearing purplish-red on the external ear.
