Metastatic adrenal neuroblastoma in an adult.

BACKGROUND

Neuroblastoma (NB) is a common malignancy in children, but rarely occurs in adults. Accepted unfavourable prognostic factors include age > 1 year, low histologic grade and advanced stage, MYCN amplification, chromosomal aberrations, elevations of neuron specific enolase and lactate dehydrogenase, and increased catecholamine metabolites in urine or serum. In adults, abdomen/retroperitoneum are the primary sites and in children the adrenal gland.

CASE REPORT: A 51- year-old man was admitted to our hospital with hypertension and a large right retroperitoneal mass. Clinically, phaeochromocytoma was suspected. Tumour resection revealed adrenal NB grade III. Chemotherapy according to the paediatric German Neuroblastoma Trial (NB97) was started. Follow-up computed tomography showed regression of the enlarged mediastinal and retroperitoneal lymph nodes. Because of local and systemic progression palliative radiochemotherapy was started. The patient died 9 months after diagnosis.

CONCLUSION

To the best of our knowledge this is the oldest NB patient registered so far in Germany. Currently there are no standard treatment guidelines for patients with NB in adulthood. Collection and evaluation of data in adult patients with this tumour are warranted in order to optimise treatment strategies.
