Auricular pseudocyst

An auricular pseudocyst is a rare and benign cystic swelling resulting from intracartilaginous accumulation of fluid within the pinna.

While it can occur at any age and in either gender, it typically presents in middle aged males with a mean age of presentation being around 35-40 years 1.

Typically presents as a painless auricular swelling (typically develops over a period of 4 to 12 weeks).  Minor discomfort and mild inflammatory signs could be occasionally present 1.

The exact aetiology is not well known while some consider a repeated minor injury playing a role in its development.
