Pheochromocytoma and renal artery stenosis.

Cases with concurrent pheochromocytoma and renal artery stenosis, two "surgically curable" hypertensive disorders, are rare. The stenosis is generally secondary to direct compression or stretching of the renal artery by the tumor. Five such cases are reported. Sometimes the tumor and the renal artery stenosis occur independently giving rise to some pathogenetic queries. Diagnosis and therapy are briefly discussed.
