Recurrent Blandin-Nuhn mucocele and intralesional ethanol injection

A 21-year-old female patient presented with a swelling under the tongue that lasted about a month. A 2¥1 cm cystic lesion was found on the left side of the tongue ventral face in the physical examination, and the patient was operated. However, a partial recurrence was detected after the surgery; thereby, intralesional ethanol was administered. The lesion disappeared after the administration of ethanol, and there was no recurrence during the one-year follow-up. We presented this case to demonstrate the efficacy of this treatment method.
