SCLEROSING OF RECURRENT LYMPHANGIOMA USING OK-432

The authors present two cases of lymphangioma of the cervicofacial region, treated with a new investigational drug in North America, OK-432 (picibanil), a sclerosing agent intralesionally injected. Both patients had been treated surgically and had recurrence of the tumor. Intralesional injection of OK-432 without aspiration was employed for the first patient, and after aspiration in the second patient. A change in consistency of the tumor, manifested by softening, was followed by marked shrinkage. No complication either locally or systemically has occurred during the follow up period (10 to 16 months). In both cases, satisfactory results were obtained, resulting in definite reduction in size and improvement in cosmetic appearance. The authors recommend OK-432 intralesional injection for surgically challenging lymphangioma. Their results support those of a recent Japanese study using OK-432 as sclerosing therapy for unresectable lymphangioma. Copyright (C) 1995 by W.B. Saunders Company
