[2][3]: 681 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.
The auricle pseudodocyst can occur independently, but prior trauma is a significant factor in initiating tissue plane separation within cartilage, leading to fluid buildup in the affected area.
[6][7] Pseudocyst of the auricle can happen on its own, but the majority of authors concur that prior trauma is a key initiating factor for the separation of tissue planes inside the cartilage, which is followed by fluid buildup in that area.
[9] Cyst-like lesions with a fibrous, cartilaginous, and granulation tissue lining devoid of epithelium, coupled with ahyalinizing degeneration of the surrounding cartilage, are typical histopathologic features.
[15] On the other hand, the risk of perichondritis aggravated by the development of a cauliflower deformity or floppy ear is associated with invasive treatment techniques, and recurrences may occur afterward.
