title: Lymphangioma. A long-term follow-up study.
abstract: At the Hospital for Sick Children 177 patients with lymphangioma, exclusive of those who had intra-abdominal lesions, were seen between 1927 and 1964. Forty-nine of these (aged 8 to 41 years) were available for follow-up examination. The results of treatment by surgical excision, aspiration, incision and drainage, and radiation are reported. No cases confirmed histologically as lymphangioma underwent spontaneous regression. Two histologically unconfirmed cases underwent partial regression. Four of the 11 who were left with lymphangioma tissue at operation never had significant recurrences. Therefore, this clinical study does not clarify the possible role of spontaneous regression in lymphangioma. Extensive surgery is the treatment of choice whenever feasible, but in unilocular or bilocular cystic lymphagnioma subsequent regression can be expected after palliative treatment (aspiration, or incision and drainage). Clinical and pathological criteria should be established for differentiation between lymphangioma and primary lymphedema. Lesions involving subepithelial, subdermal, and subcutaneous or internodal networks of lymphatics will produce lymphagioma; lesions of the collecting lymphatic trunks will result in lymphedema.
