Abstract
Tumors of the sublingual gland are rare, and Pleomorphic adenomas in this location are exceedingly rare. A 58-year-old woman was referred to our hospital because of a submucosal mass in the left oral floor. MRI showed a well demarcated sublingual mass. Fine needle aspiration biopsy revealed that the mass was comprised of spindle cells without atypia, suggesting pleomorphic adenoma. Under general anethesia, the tumor and the left sublingual gland were removed en bloc after removal of the left submandibular gland through an extra-oral approach. A well encapsulated tumor was present in the anteroinferior part of the left sublingual gland. The histopathological diagnosis was pleomorphic adenoma.
