RESUMO
We report a case of vulvar silicone granulomas following injection of liquid silicone into the labia. The patient is a 51-yr-old female who presented with vulvar pain and enlarged, indurated labia majora. In the past, she had undergone bilateral labial cosmetic augmentation with a silicone-based filler injected directly into the labia and into the gluteal regions. This had been performed in a nonmedical setting. At surgery, oblong firm soft tissue masses were removed from both labia. Microscopically, the lesions demonstrated replacement of the subcutaneous adipose tissue by fibrous tissue containing innumerable round empty spaces of different sizes, either within or surrounded by macrophages and occasional foreign-body giant histiocytes. The clear vacuoles corresponded to silicone fluid which had been dissolved during tissue processing. There are only rare case reports of vulvar silicone granuloma in the literature, and these were due to migration of silicone to the vulva from distant sites. Our report details a case of vulvar silicone granuloma secondary to direct injection of liquid silicone material into the labia.
