Abstract

A pseudocyst of the auricle is a rare disease with an unknown cause. We report a female patient who had auricular pseudocyst after a soft tissue filler injection in that area. The cyst was excised under local anesthesia. The entire cyst wall was removed and some portion of the surrounding cartilage was also resected. A silastic drain was inserted and the compressive dressing was maintained for 5 days. The swelling subsided gradually and no recurrence was noted after a 1-year follow up. Histopathology confirmed that the cyst has no epithelial lining on its inner surface. Patients and doctors should be aware that a soft tissue filler can cause a pseudocyst when injected into the auricle.
