A 74-year-old Caucasian woman presented with a 2-week history of multiple nodules in both lips and perioral region that caused her mild discomfort while eating. The patient reported hyaluronic acid infiltration on both lips 5 months prior to presentation. The examination revealed multiple, well-defined, millimetric, and firm nodules on both lips and oral mucosa. An excisional biopsy of one of the nodules was performed under local anesthesia. Histopathological analysis demonstrated acute eosinophilic inflammation, fibrosis, and granulomas on mucoid material, positive for colloidal iron stain and Alcian blue stain, alongside a minor salivary gland showed mild atrophy, fibrosis, and fat infiltration. Enhancement of the aged lip using hyaluronic acid, to restore the bulkiness and elasticity that have been lost with age, is very common. Nevertheless, soft tissue fillers are used in a wide age range. Hyaluronic acid represents 78% of the dermal filler injections in the United States, been the second most popular nonsurgical cosmetic procedure after botulinum toxin injection. Foreign body granulomatous reaction is a rare delayed complication that has been well documented elsewhere and it has been associated with poor injection technique. Although it also has been related to hypersensitivity reactions that may be caused by impurities developed during the bacterial fermentation process, treatment of granulomatous reactions with hyaluronidase is recommended.
一名74岁的白种女性患者,双唇及口周区域出现多个小结节,病史2周,进食时伴有轻度不适。患者自述就诊前5个月曾在双唇行透明质酸注射。检查发现双唇及口腔黏膜有多个边界清晰、毫米大小的坚实结节。在局部麻醉下对其中一个结节进行了切除活检。组织病理学分析显示,在黏液样物质上有急性嗜酸性炎症、纤维化和肉芽肿,胶体铁染色和阿尔辛蓝染色呈阳性,同时小涎腺显示轻度萎缩、纤维化和脂肪浸润。使用透明质酸来改善老化唇部,恢复因年龄增长而丧失的丰满度和弹性,这非常常见。然而,软组织填充剂的使用年龄范围很广。在美国,透明质酸占真皮填充剂注射量的78%,是仅次于肉毒毒素注射的第二大最受欢迎的非手术美容 procedure。异物肉芽肿反应是一种罕见的迟发性并发症,在其他地方已有充分记录,并且与注射技术不佳有关。尽管它也与细菌发酵过程中产生的杂质可能引起的超敏反应有关,但建议用透明质酸酶治疗肉芽肿反应。
