[Differential diagnostic considerations about a tumour on the tongue of a 43-year-old man].

Schwannomas are benign tumours originating from the Schwann cells that ensheath peripheral nerves. 25-40% of schwannomas are located in the head and neck area, only 1% of these are found in the oral cavity. Schwannomas are slow-growing benign tumours with little or no occurrence of malignant transformation. A case report of a 43-year-old man presenting with a 2 ´ 1.5 cm protruding tumour on the anterior part of the tongue is reported. The patient complained of difficulty eating and a tendency to bite on the tumour. Biopsy showed a benign schwannoma. Total excision in local anaesthesia was performed.
