히알루론산 필러 주입에 의해 발생한 안면부 거짓낭 1예

Administration of a hyaluronic acid (HA) filler injection is a common aesthetic procedure widely used for facial soft-tissue augmentation. Owing to their low immunogenicity, hyaluronic acid fillers have rarely been linked with serious long-term adverse effects. Although generally safe, reports of adverse events linked to hyaluronic acid filler injection are increasing following its extensive usage globally. We describe the case of a 33-year-old woman who presented with multiple facial nodules at sites of filler injection. To the best of our knowledge, this is the first reported case of facial pseudocyst related to monophasic hyaluronic acid filler injection, in Korea. (Korean J Dermatol 2017;55(6):346∼350)
