Cauliflower ear
An auricular hematoma is a collection of blood (hematoma) in the outer ear flap (auricle), causing swelling, redness, and pain.
It is caused by injury to the ear that has caused bleeding in the soft cartilage, as may happen during contact sports. Severe or repeated hematomas may result in permanent deformity of the outer ear, a condition commonly called cauliflower ear.
Immediate treatment is with ice packs to reduce swelling.
In severe cases, the hematoma may be drained and a compression bandage applied. Cosmetic surgery may be needed to correct a cauliflower ear
