Polyacrylamide hydrogel (PAAG) has been widely used in Russia and China as an injection material for cosmetic surgery. We report the case of a 36-year-old woman who noted breast enlargement subsequent to breastfeeding, after a PAAG injection. In 2016, a PAAG injection was administered to her under both mammary glands at a nearby cosmetic surgery clinic for breast augmentation. After she started breastfeeding following delivery in 2020, she was admitted to our hospital because of a rapid left breast enlargement and unbearable pain. Contrast-enhanced chest computed tomography revealed marked fluid retention in the left breast, and the mammary gland tissue had been pushed outward. A skin incision revealed a significant amount of yellowish-white odorless fluid accumulation. On surgery, a foreign body remained around the pectoralis major muscle, but complete removal was impossible. Currently, 3 months have passed since the operation; however, the patient has not experienced any further pain. There have been many reports on complications caused by PAAG injection. In our case, commencing breast feeding after receiving PAAG injections resulted in a rapid unilateral breast enlargement, and there is no similar report from Japan. In this case, suppressing lactation and rapid removal of the foreign body is the most important measure. It is difficult to completely remove PAAG once it has been injected. PAAG injections for breast augmentation should be avoided in all patients.
聚丙烯酰胺水凝胶（PAAG）在俄罗斯和中国已被广泛用作整形手术的注射材料。我们报告了一例36岁女性的病例，该女性在接受PAAG注射后，哺乳期间出现乳房增大。2016年，她在附近的整形手术诊所接受了双侧乳腺PAAG注射以隆乳。2020年分娩后开始哺乳时，她因左侧乳房迅速增大且疼痛难忍而入住我院。胸部增强计算机断层扫描显示左侧乳房有明显的液体潴留，乳腺组织被向外推移。皮肤切口显示有大量黄白色无味液体积聚。手术时，胸大肌周围仍有异物残留，但无法完全清除。目前，手术已过去3个月；然而，患者未再经历任何疼痛。关于PAAG注射引起的并发症已有许多报道。在我们的病例中，接受PAAG注射后开始哺乳导致单侧乳房迅速增大，日本尚无类似报道。在这种情况下，抑制泌乳和迅速清除异物是最重要的措施。PAAG一旦注射就很难完全清除。应避免所有患者使用PAAG进行隆乳注射。
