Abstract
|
|
|
|
Myxomas can be divided into two groups: those derived from the facial skeleton, and those derived from external skeletal soft tissue. Soft tissue myxomas of the head and neck are uncommon, with fewer than 50 cases reported. In any form and location, myxoma of parotid gland is rare. We report a case of myxoma arising from the left superficial lobe of the parotid gland with good long-term follow-up after superficial parotidectomy with tumor excision. A 49-year-old man was referred to our department of plastic and reconstructive surgery with a painless palpable mass that had persisted in the left mandible angle region for 2 years. Excision of the facial mass and superficial parotidectomy with facial nerve preservation were performed. The biopsy result was myxoma. Long-term follow-up for 22 months showed favorable results without evidence of recurrence but with temporary facial nerve weakness right after the surgery. Myxoma should be considered as a differential diagnosis when benign tumor of the parotid gland is being considered.
