Abstract
Cystic hygroma usually occurs in infants and children, but rarely develops in adults. We report a case of cystic hygroma arising in the right parotid gland region of a 64-year-old man. The patient presented with a soft and painless swelling mass. Ultrasound, CT, and MRI findings suggested a cystic lesion in the right parotid gland. We performed surgical resection on March 12, 2009. Histopathological examination revealed cystic hygroma. Surgical excision is the most effective approach in the treatment of cystic hygroma, however, the complete removal of lympangiomas in children may be difficult in the case of insinuation of the tumor into the adjacent neck structures. In cases with incomplete removal, recurrence is therefore common. In contrast, cystic hygromas in adults are generally encapsulated masses and can usually be excised completely.
After operation in this case, there was no evidence of recurrence.
