Abstract

Auricular endochondral pseudocyst is a very rare, benign intracartilaginous cystic lesion which most commonly presents as a cystic mass in the anterior plane of the auricle. We present a case report of a 48-year-old man with a fluctuating lesion of 3 week s duration on the left auricle, with no specific history of trauma or disease. Initial incisional drainage revealed an abundance of serous fluid, which quickly recurred. Surgical removal of the hypertrophic perichondrium forming the pseudocyst anterior wall and ear cartilage curettage was carried out with intraoperative absolute alcohol sclerotherapy, followed by compression dressings. The auricle healed uneventfully, with a good final cosmetic result and no recurrence within a 6-month follow-up period. We report this unusual case as the first in Korean plastic surgery with a review of the literature.
