RESUMO
AIM: Localised juvenile spongiotic gingival hyperplasia (LJSGH) is a benign lesion occurring in young patients as gingival erythema and overgrowth, typically localised on gingiva of maxillary incisors. The aim of this work is to report a case of LJSGH where complete spontaneous regression was achieved together with a review of the literature on the topic. CASE REPORT: An 8-year-old girl was referred for a gingival painless lesion, which had appeared spontaneously one year before and was refractory to periodontal treatment. Intraoral examination showed a well-defined, red gingival overgrowth involving the left maxillary central incisor, without involving the marginal gingiva. The clinical diagnosis of LJSGH was made, due to the pathognomonic aspect. The patient was periodically recalled for 43 months; at the last visit, the lesion was spontaneously resolved. RESULTS: LJSGH is not plaque-related and not responsive to periodontal treatment. Surgical removal of the lesions correlates with high recurrence, while spontaneous resolution over time has been hardly demonstrated. CONCLUSION: Follow-up of LJSGH may be an option of care, alternative to surgery, in selected cases.
