Perichondritis

A painful, red ear is the most common symptom. At first the infection will look like cellulitis (a skin infection), but it rapidly progresses to involve the perichondrium. The area of redness usually surrounds the area of trauma, which may be an abrasion or laceration. There can also be fever, and in more severe cases, fluid draining from the wound.

The diagnosis of perichondritis is usually made by history and physical exam. If there is a history of trauma to the ear and the ear is red and very tender, then the presumed diagnosis is perichondritis. There may be an abnormal change in the shape of the ear.
