The cystic hygroma, or cystic lymphangioma, is a multilocular cystic tumor of a benign neoplastic nature which is a lymphatic origin by congenital defect of lymphatic vessel. The lymphatic space is lined with single layer of endothelium, containing serous or serosanginous fluid. Most often it occurs at birth or early life.

The cystic hygroma usually occurs mainly in cervical region and axilla. The rest were scattered at various sites involving mediastinum, retroperitoneal space, pelvis, groin, abdominal wall and thigh.

Recently the authors had experienced one case of cystic hygroma of the anterior neck and retropharynx. The patient, 7 year-old-male child, had rapidly enlarging cystic mass in left upper cervical area. The cystic mass was removed completely and confirmed cystic hygroma microscopically.
