title: Mitochondrial abnormalities in human phaeochromocytoma.
abstract: Mitochondrial abnormalities are reported in four cases of phaeochromocytoma. These abnormalities include swelling and scant cristae, intramitochondrial dense bodies, septate-like junctions, intercristal fusion plus spheroidal bodies, and intramitochondrial rodlets. These structural mitochondrial changes are associated with reduction in activity of the mitochondrial enzymes, monoamine oxidase and succinic dehydrogenase.
