[Pheochromocytoma mimicking septic shock].

A tumour arising from chromaffin cells, the pheochromocytoma may be associated or present with hypotension and result in a lethal shock. The authors report a rare case of pheochromocytoma simulating septic shock. They review the mechanisms by which hypersecretion of catecholamines may cause shock. The detection of pheochromocytoma in its atypical presentation is essential for early diagnosis and the reduction of mortality related to this condition.
