XXXX in a Chinese--literature review and case report.

@entity1 @entity5 @entity75 @entity14253 @entity528 @entity4724
@entity4724 is an unusual @entity5 . It is predominantly found in Caucasians and is rare in non-Caucasians. The chief affected area of the @entity5 is the parotid gland. Of all @entity14253 , @entity4724 is the only lesion which is truly multicentric so it may have a second @entity75 , not a recurrence. The peak incidence is in the sixth decade of life. In sexual distribution, there is a male predominance but the incidence of female is progressively increasing. According to Lemelas's study, the increase in female incidence may relate to the increasing population of cigarette smoking of @entity1 . Bilateral parotid gland involvement is uncommon. The chief treatment of the @entity5 is surgical excision. The surgical methods include enucleation, superficial parotidectomy, total parotidectomy. It is very important to protect the facial nerves from injury during surgery. In this paper, we report a case of bilateral metachronous @entity4724 with @entity528 in a Chinese. Other than literature review and case report, four different methods to protect facial nerves from injury were briefly described.
