The typical lesions are small, purulent, periauricular ulcers. Enlargement and coalescence result in extensive lesions that may ultimately destroy portions of the external ear. The histopathologic findings are acute and chronic inflammation with necrosis. Treatment consists of long\u2010term systemic corticosteroids.
