These are situated on the basis of skull, at the level of neck, in the thorax and the belly. Some paraganglioma are functional and secrete cathecolamines and others are diagnosed after surgery in the histological study of the operating piece. Through a retrospective study concerning height patients having paraganglioma extra surrenalien brought together in 20 years. We have specified theirs phenotypes.

The paraganglioma is a tumor with various phenotypes. Theses are voluminous or smalls, uniques or multiple, secretant or no and have a risk of recurrence and degenerescence. This fact, it may be requiring a long term surveillance. Because of the family character of this pathology (1/3 cases) a genetic study is proposed at every patient in particulary if he young, has multiple localizations or presents a cunning shape.
