[Pheochromocytoma simulating myocardial infarct. Apropos of a case].

The authors report the case of a pheochromocytoma in a 67 year old man in whom the initial clinical presentation suggested myocardial infarction. Pheochromocytoma is usually an adrenal tumour with a very variable clinical symptomatology. It is very rare for cardiac disease to be a presenting symptom. The diagnosis was suggested by major blood pressure abnormalities occurring after starting medical treatment for infarction. Pheochromocytomas may cause serious cardiovascular disorders. The diagnosis must be suspected in the presence of atypical signs, an essential requirement to reduce the mortality of the disease.
