[Pheochromocytoma as a simulator of cardiac pathology].

Pheochromocytomas are rare neuroendocrine tumors that can present as hypertensive crises or serious cardiac and cerebrovascular complications that endanger the patient's life. Two unusual cases of adrenergic crises induced by pheochromocytoma with cardiovascular manifestations are presented, one with multiple complications/multiorgan failure, fatal outcome and definitive diagnosis in the post mortem autopsy, and another with a satisfactory evolution after diagnosis and appropriate treatment.
