This article reports the efficiency of intralesional corticosteroid injection in the treatment of a recurrent oral mucocele in a pediatric patient.<br> <strong>Case presentation:</strong> A 7-year-old girl presented with the chief complaint of a painless swelling on the lower lip. A gradual increase in size with some episodes of emptying was noticed. The intraoral examination revealed a sessile, nodular and exophytic lesion on the lower lip. Two consecutive intralesional injections of 40 mg/ml triamcinolone acetonide were done at the base of the lesion. A significant reduction in size was observed after the first injection, and the lesion disappeared after two weeks. No recurrence was noticed during the one-year follow-up.<br> <strong>Conclusion:</strong> Intralesional corticosteroid injection may be considered a less invasive and cost-effective approach for the management of oral mucoceles.
