Cystic lymphangioma is usually seen in the submandibular or cervical region of infants. A case of a 15-year-old man with cystic lymphangioma in the parotid region encountered in our oral surgery is reported.
CT scan and MRI were the most effective methods that allowed us to estimate the qualities and lesions of cystic lymphangioma. Though it seems better to remove it completly in one operation, it is difficult to do so. Thus there is a potential risk of recurrence after surgery. A small cystic lymphangioma sometimes tends to be cured completely. In addition, bleomycin injection and radiation therapy are frequently effective when we can't remove it completely in one operation.
Fortunately, the operation in this case succeeded and no recurrence was observed for 9 months after operation.
