Lymphangioma in children.

The topic of lymphangioma is reviewed. Included in the text are the embryology, classification, clinical presentation, and treatment. Eight case reports are included. One case involved the skin, two presented with a submandibular mass, one had both a facial lymphangioma and a cystic hygroma of the floor of the mouth, and there are two cases of involvement of the tongue, and two cases of classical cystic hygroma of the neck. The rate of involution is probably higher than previously thought. Indications for surgery are suggested. This diagnosis must be considered in the differential diagnosis of a mass presenting in the head and neck of a child.
