[Ganglioneuroma of the adrenal gland]

149 patients with adrenal incidentalomas were examined. Sixty-eight cases were histologically confirmed, five of them had ganglioneuromas. On the basis of these patients history current knowledge of this benign tumour was summarized. Histological and pathological characteristics of one tumour suggest that ganglioneuromas may develop by maturing of malignant neuroblastic tumours. The clinical symptoms (abdominal pain, meteorism) were local. In 2 of 5 cases mildly elevated levels of urinary vanillylmandelic acid and catecholamine could be measured. One patient had persisting hypertension after surgery. In an other patient previous diarrhoea stopped after the removal of tumour. On the basis of ultrasound and computertomographic features, the size and origin of a tumour and its relation to the surrounding organs can be well characterized. One patient was inoperable because of an infiltratively spreading tumour, but during five years of follow-up no tumour progression could be observed with computertomography. After surgery we could follow only 2 of 4 patients. Until now no recurrence of tumour were detected.
