Surgical management of lymphangiomas in adults.

Lymphangiomas are uncommon benign congenital tumours. Most occur in the head and neck region and the vast majority present before the age of two. This paper describes the presentation and management of four cases presenting after puberty and involving the parotid gland. The cases are unusual in that all were intimately associated with the facial nerve and in an older population. The value of selective neck dissection and facial nerve exposure as an approach to these lesions is discussed.
