ABSTRACT

Cystic hygroma is a benign developmental malformation of the lymhatic tissue, which is seen as fingerlike multiloculated cystic extensions, infiltrating to surrounding tissues. Cystic hygroma usually occurs in cervicofacial area in affected individuals and upper extremity is extremely rare involvement area. We presented a patient with cystic hygroma located to right upper arm. Com-plete surgical resection with negative surgical margins is the best treatment.
