[Lymphangioma circumscriptum cysticum following surgical and radiologic therapy].

Abstract

Four cases of lymphangioma circumscriptum cysticum are reported that developed 3-43 years after surgical or radiological therapy. Clinically, recurrent vesicles occurred in the treated areas. Manifest lymphatic edema was observed in only one case. The histologic picture showed papillary ectatic lymph vessels with no indication of proliferation or malignancy. Because of the postoperative tendency to recidivism, extensive excisions are not indicated. Manual lymph drainage was found to be effective.
