Occurrence of pheochromocytoma in Rochester, Minnesota, 1950 through 1979.

Abstract

For the 30 years from 1950 through 1979, the population of Rochester, Minnesota, averaged 45,800, resulting in almost 1.4 million person-years of observation. During that time, 11 cases of pheochromocytoma were diagnosed in this population; thus, the average annual incidence rate was 0.8 per 100,000 person-years. With the inclusion of two additional diagnosed familial cases, the incidence rate would be 0.95 per 100,000 person-years. Five of the 11 cases were diagnosed initially at autopsy.
