case_images: Intraoral clinical examination showed exacerbated accumulation of dental biofilm, erythematous and swollen gingiva, and mild pain (Figure 1).
case_images: (a) Displacement of the epithelium after an air jet over the buccal gingiva, causing blisters (Nikolsky positive sign). (b) Removal of the gingival fragment. (c) Surgical cement to protect the surgical area. Intraoral images before treatment: (a) Nikolsky's sign; (b) appearance after the incisional biopsy;(c) appearance with the surgical cement.

case_images: An air jet was applied to the mucosa, and Nikolsky's sign (Figure 2(a)) was observed. It was a difficult procedure owing to epithelial detachment and fragility (Figure 2(b)). Surgical cement was used as a postoperative dressing (Figure 2(c)).
case_images: Follow-up after prednisone treatment. Intraoral image 40 days after the beginning of treatment, showing erythematous gingiva.
