[Pheochromocytoma-ganglioneuroma of the adrenal gland].

Two cases of a rare neuroectodermal compound tumor (pheochromocytoma-ganglioneuroma) of the adrenal were described. They were found in 2.85% of all neuroectodermal adrenal tumors investigated during 20 years. One tumor was diagnosed bioptically in a patient with hypertension. The other one was found incidentally in an autopsy. In both of the them, the major part was feochromocytoma. The structures of ganglioneuroma were only focal. Chromogranin A was relatively strongly positive in pheochromocytes which contained neurosecretory granules. In gangliocytes, the neuron-specific enolase was strongly and serotonin weakly expressed.
