Inflammatory myofibroblastic tumour of larynx.

Inflammatory myofibroblastic tumour (IMT) is a benign pseudoneoplastic proliferation, mainly developing in the lung and extremely rare in the larynx. A patient with a two-month history of dysphonia and a polypoid left true vocal fold tumour is presented. Histological and clinical knowledge of this lesion is important to exclude a misdiagnosis (e.g. malignant epithelial or mesenchymal tumours) and an inappropriate treatment.
