[Familial occurrence of pheochromocytoma].

Familial occurrence of pheochromocytoma in mother and two sons (11 and 14 years old) is described. The diagnosis was based on biochemical tests and localization methods. Bilateral tumors were demonstrated on computerized tomographic scanning in two of our patients. No association with multiple endocrine neoplasma was found. Removal of the tumors resulted in normalization of blood pressure and biochemical parameters. The histopathological examination of the tumor confirmed the diagnosis. A possibility of familial occurrence should be considered in patients with pheochromocytoma and appropriate diagnostic tests must be performed in their near relatives.
