Surgical management of cystic hygroma is very challenging since it has a thin wall consisting of endothelium which can easily be torn during its enucleation leading to recurrence. The other treatment options are intralesional injection of OK-432, triamcinolone followed by surgical excision, if necessary, injection of sclerosing agents, repeated aspiration, radiotherapy and finally spontaneous regression without any form of treatment. This is a case report of cystic hygroma of parotid region where regression occurred without any form of treatment.
