[Familial pheochromocytoma: a family studied for 3 generations]

A family with a very high prevalence of pheochromocytoma (62%, i.e. 100% in the 1st generation and 75% of the second one) is described. The proband was a 19-year-old woman with a 30 g right-side tumor, who died at 24 years because of a heart failure. Both sisters of the proband developed a right-side pheochromocytoma at 13 and respectively 14 years of age and are now normotensive after surgical exeresis. One of them had 3 sons: 2 with pheochromocytoma and a third one dead at 9 years of age for pulmonary oedema. Accuracy is needed in studying relation of all subjects with pheochromocytoma.
