Endochondral pseudocyst of the auricle is an uncommon condition that affects predominantly Chinese males, with many reports studying this condition in homogenous Chinese populations. There have been few large-scale reports describing the features of this disease among the other Asian groups. In one of the largest series described to date, we report the epidemiological features, clinico-pathologic characteristics, and success of surgical treatment in 40 patients of different Asian groups presenting with pseudocyst of the auricle. Results showed a Chinese predominance (90 per cent), followed by Malays (five per cent) and Eurasians (five per cent). All had unilateral presentations apart from one patient. Most (55 per cent) presented within two weeks of auricular swelling. Few (10 per cent) had a history of trauma. The pseudocysts predominantly affected the concha (61 per cent). Surgery comprised excision of the anterior wall followed by local pressure application. Only 2.5 per cent had recurrence after surgery. These findings confirm earlier understood features of this disease while revealing some notable variations.
