Pseudocyst of the auricle is a cutaneous condition characterized by a fluctuant, tense, noninflammatory swelling on the upper half of the
ear, known as the auricle or pinna.[1][2]: 681 [3][4][5] It is called a "pseudocyst" because it is not a true cyst, but rather a collection of fluid or blood trapped within the tissue layers of the auricle.
Pseudocysts of the auricle are usually painless and may occur due to trauma or injury to the ear, such as a blow to the ear or repetitive pressure on the area. They are typically benign and do not pose significant health risks. However, they can cause cosmetic concerns or discomfort for some individuals.
