A single lesion on the front part of the ear is usually the initial sign of pseudocyst of the auricle. Pseudocysts of the auricle appear as flesh-colored, nontender, noninflammatory cystic lesions and progress gradually over a 4- to 12-week period. Their diameters range from 1 to 5 cm. Usually, the lesions start off soft and get firmer with time.
Perichondritis is inflammation of the perichondrium, a layer of connective tissue which surrounds cartilage. [2] A common form, auricular perichondritis (perichondritis auriculae) involves infection of the pinna due to infection of traumatic or surgical wound or the spread of inflammation into depth (e.g. Infected transcartilaginous ear piercings).

The skin that covers this cartilage is extremely thin with virtually no subcutaneous fat while also strongly attached to the perichondrium, which is richly vascularized to supply the avascular cartilage. [1] Cauliflower ear can also present in the setting of nontraumatic inflammatory injury of auricular connective tissue such as in relapsing ...
