Lymphangioma is not rare in the body, but is very rare in the oral cavity. Here, we reported a case of lymphangioma in an infant's lower lip and buccal mucosa.<BR>The patient was a male one year and 2 months old. A month after his birth, his mother noticed multiple granular vesicles of right lower lip of the patient. Thereafter, the mother scratched the lesion with her nails, but the lesion recurred several times and gradually proliferated.<BR>The patient was referred to us with a chief complaint of swelling of the right lower lip. During the course of the first medical examination, a difluse, elastic soft, thumb-tip sized tumor with numerous vesicles on the surface was found in the region of lower lip and buccal mucosa. The clinical diagnosis was lymphangioma. The lesion was excised several times, treated with cryosurgery many times, was vaporized by laser irradiation, and treated with free transplantation of buccal mucosa, but the lesion recurred every time.<BR>Histologically, the excisional specimen consisted of dilated lymphatic vesseles, therefore the lesion was diagnosed cavernous lymphangioma.<BR>A year and 6 months after the last operation, the lower lip of the patient revealed relative symmetry without proliferation of the recurrent tumor.
