title: Bilateral submandibular gland oncocytoma in a patient with multiple endocrine neoplasia 2B syndrome and neurofibromatosis type 1: an unusual case.
abstract: Oncocytomas are unusual neoplasms of the head and neck that occur mainly in the parotid gland. The authors report a case of bilateral submandibular gland oncocytoma in a patient with multiple endocrine neoplasia 2B syndrome and neurofibromatosis type 1. Histopathology of the resection specimens demonstrated lymphovascular invasion but no other aggressive features. This was a highly unusual feature in an otherwise rare benign tumour.
