In the oral cavity, lymphangioma is a rare, non-odontogenic, benign neoplasm which originates from lymph vessels. This lesion is common in the first decade of life and mostly occurs on the dorsal surface and lateral border of the tongue and rarely arises on the palate, gingiva, buccal mucosa and lips. Treatment of the lesion is surgical excision, however in recent years Neodymium Yitrium Aluminum Garnet (Nd-YAG) laser surgery has become favorable due to its many advantages. This case report presents the treatment of a buccal lymphangioma in a 10-year-old girl by Nd-YAG laser.
