Mucocele is a common benign lesion of the oral mucosa in pediatric populations, typically managed through surgical excision. However, early recurrence remains a clinical challenge, particularly among adolescents. This case report describes the clinical presentation, surgical management, and follow-up of a 15-year-old boy with recurrent lower lip mucocele based on history taking, clinical and photographic examinations, and a literature review. A 15-year-old boy presented with swelling on the right lower lip following accidental trauma. Clinical examination suggested a mucocele, and surgical excision was performed. Initial healing was uneventful; however, recurrence occurred within two weeks at the same site. A second surgical intervention resulted in complete resolution without further recurrence. Early recurrence may be associated with factors such as incomplete removal of adjacent minor salivary gland tissue, persistent local trauma, and patient-related behavioral habits. Adolescents may have an increased risk due to parafunctional habits and variations in tissue response. This case highlights that early recurrence of mucocele can occur despite apparently successful initial treatment. Meticulous surgical technique, including complete removal of the involved glandular tissue, combined with patient education and close postoperative monitoring, is essential to minimize recurrence
