Laser Ablation of Blandin and Nuhn Mucocele: A Rare Case Report

Abstract

Blandin and Nuhn glands are the mixed type of minor salivary glands located on the anterior ventral surface of the tongue. Mucoceles are rarely associated with Blandin and Nuhn gland. Out of 400 mucoceles reviewed by Harrison, only 9 arose on the tongue. Its differential diagnosis ranges from soft-tissue abscess to pyogenic granuloma, oral hemangioma, lymphangioma, lipoma, and squamous papilloma. This is a rare case report emphasizing the laser ablation of Blandin and Nuhn mucocele. The diagnosis of Blandin and Nuhn mucocele was made based on its anatomical site, size, flaccid nature, and frequent change in size characteristically increasing after consumption of food. Laser ablation was opted for the excision because it enables minimal bleeding, scarring, postoperative discomfort, and low recurrence compared to the conventional surgical excision. Histopathological examination revealed extravasation type of mucocele, suggesting that trauma may be the initiating factor.
