title: A clinico-pathological classification of laryngeal paraganglioma.
abstract: A case of metastatic laryngeal paraganglioma is presented. We have reviewed the current world literature on this entity and thereby identified two apparently distinct types of this rare lesion (type I and type II). The histopathological features are unhelpful in discriminating these two types and this is instead based on clinico-epidemiological differences. The latter are annotated and discussed with respect to prognosis and management. A true estimate of the frequence of type II (potentially malignant) awaits the utilization of the recent improvements in diagnostic techniques.
