Pseudocyst of the auricle

Medical condition of the ear

Pseudocyst of the auricle, also known as auricular pseudocyst, endochondral pseudocyst, cystic chondromalacia, intracartilaginous auricular seroma cyst, and benign idiopathic cystic chondromalacia, is a cutaneous condition characterized by a fluctuant, tense, noninflammatory swelling on the upper half of the ear, known as the auricle or pinna. Pseudocysts of the auricle are nontender, noninflammatory cystic lesions that progress over a 4- to 12-week period, ranging from 1 to 5 cm in diameter. They are usually unilateral, often on the right ear, but can also present bilaterally.
