Cystic hygromas occur most commonly in the neck. Rarely are they known to involve the axilla, groin, mediastinum, retroperitoneum, pelvis, mesentery, omentum and spleen.

The diagnosis of cystic hygroma was made by surgery and subsequently confirmed after histopathological examination. Because of rarity of cystic hygroma in gluteal region this case in being reported.
