This is to report a case of cystic hygroma occured in the left submandibular area of 12 year-old male patient. The patient was admitted to Department of Oral and Maxillofacial Surgery, Kyung-Hee University Medical Center with the chief complaints of left submandibular swelling. Cystic hygroma are a benign neoplasm of developmental origin that are characterized by large endothelial-lined space and found predominantly in the region of the head and neck, commonly in the posterior trianglar of the neck, but in this case, the lesion was found in the anterior triangle. In this case, cystic hygroma is not invade the floor of the mouth and base of the tongue and surgically excised specimen is ovoid, lobulated and 6㎝ × 2㎝ × 4㎝ in size and that is filled with watery, straw-colored fluid. The histological appearance is that of multiple dilated and collapsed lymphatic channels lined by a single layer of flattened endothelium. Focal lymphocytic infiltration as well as small sprouts or buds of lymphangiomatous tissue may extend into adjacent tissue. It is best treated by surgical excision soon after recognition in order to prevent extensive local growth and expansion. This case is of interest because their diagnosis was made when the patient was 12 year-old male patient.
