The tumor was a unilocular cystic benign tumor covered with thin capsule and removed from the surrounding tissue. The second case was a 19-year old male who noticed sudden swelling on his left side of the neck following a traffic accident. The swelling was a multilocular benign cyst which contained yellowish serous liquid, as in case 1. The cyst was removed successfully. The two cases had a favourable post-operative course and there have been no signs of recurrence. Histologically the cysts contained one layer of endothelial cells and an accumulation of lymphocytes.
