title: Ectopic tonsillar tissue in the mucosa of the floor of the mouth simulating a benign tumour. Case report.
abstract: Ectopic tonsillar tissue in the mucosa of the floor of the mouth is rare. A case of a 38-year-old man with ectopic tonsillar tissue in the mucosa of the floor of the mouth is described. The lesion was manifested as a small, painless tumour. There was difficulty in establishing a clinical diagnosis, but it was thought to be a benign tumour and was removed and then examined histopathologically to confirm the diagnosis.
