A paraganglioma is rare neuroendocrine neoplasm that may develop at various body sites (including the head neck thorax and abdomen). About 97% are benign and cured by surgical removal; the remaining 3% are malignant because they are able to produce distant metastases. Paraganglioma is now the most-widely accepted term for these lesions that have been also described as: glomus tumor chemodectoma perithelioma fibroangioma and sympathetic nevi.
