An unusual occurrence of oral mucocele: A case report and literature review.

Mucocele is a lesion frequently found in the oral cavity, occurring particularly on the lower lip, then followed by the floor of the mouth, ventral portion of the tongue, buccal mucosa, and, rarely, on the dorsum of the tongue. This report presents an unusual case of mucocele on the dorsum of the tongue of a 7-year-old child. The lesion was nodular, asymptomatic, self-limited, and naturally slow growing. Due to these characteristics, only benign lesions were considered in the differential. The lesion was surgically excised without any local or general complications. A microscopic analysis of the biopsy specimen was consistent with a diagnosis of mucocele, and the patient was maintained on regular follow-up, with no signs of recurrence after 12 months. To date there have been only six cases of mucocele of the dorsum of the tongue reported in the literature. The description of this additional case is crucial for establishing the differential diagnoses of nodular lesions in this particular anatomic location. This report could contribute to the correct diagnosis and management of pediatric patients with oral lesions, by highlighting the importance of including mucocele in cases of nodular lesions on the dorsum of the tongue.
