For acne cysts on the face, it is safer to use 1 to 2 mg/mL to make sure that atrophy does not occur. On the trunk consider using 2 to mg/mL of triamcinolone. Enough suspension should be injected to see and feel the cyst become distended, but no more than mL is needed for any one cyst. One injection site per acne cyst should be adequate. If the cyst is large and soft, do not inject more volume because that can lead to atrophy. If there is a lot of purulent material inside the cyst, a quick incision and drainage (with lidocaine and a No. 11 scalpel) before injecting the steroid may be helpful.
Central giant cell granuloma (CGCG) is a benign jaw lesion predominantly found in the mandible of young female patients with a variable clinical behavior. Although surgical management is regarded as the main treatment modality for this lesion, the use of intralesional injections of steroids has been recently advocated for its treatment. In addition to this conservative management, the use of fine needle aspiration cytology (FNAC) for diagnosing CGCGs has been proven a safe and efficient approach, especially useful in cases with lesions located in esthetic regions. Herein, it is described a case of CGCG extending to the overlying gingiva of a 15-year-old male patient diagnosed by FNAC and subsequently treated with intralesional injections of a solution of triamcinolone acetonide and ethanolamine oleate that led to an important clinical remission, allowing a more conservative surgical procedure for preservation of gingival esthetics. Therefore, both procedures can be considered as management options for CGCG of the jaws.
