During the 12 years period from 1969 to 1980, 46 lymphangiomas were operated on in 16 infants and 30 children. The relationship between the postoperative complications and pathological characteristics was studied. Of these 46 cases, 16 were located in the cranio-cervical portion, 9 in the trunchal, and 10 in the abdominal cavity. Sixteen tumors had been detected prior to 1 month of the patient age. Twenty one cases were operated on prior to 6 years of age. 40 extirpations and 6 extirpationts with intestinal resection were done. Postoperative complications included 3 recurrences, 6 neurological problems, and 4 long-time lymphorroe. Pathological findings were classified into three types; cavernous 7, cystic 29, and others Remarkable infiltration into the normal tissue was seen in 33 cases, and inflammation with lymphocyte concentration in 8 cases. It should be noted that lymphangiomas which developed postoperative complications commonly showed the significant infiltrative pathological findings.
