Cystic hygroma in an adult: a case report

Cystic hygromas are benign lesions arising due to an abnormality in lymphatic development and only rarely present in adults. Adequate radiological imaging prior to surgery is important as incomplete excision often leads to recurrence. Several adjunctive therapies have been shown to be beneficial in recurrent or inaccessible lesions but these are not in common use. We describe the case of a cystic lymphangioma appearing in adulthood that presented a diagnostic and therapeutic challenge.
