[Adrenal ganglioneuroma. Report of a new case].

Ganglioneuroma is a benign neoplasm arising from neural crest tissue and is composed of mature ganglion cells and Schwann's cells. Most ganglioneuromas arise in the posterior mediastinum followed by the retroperitoneum. Only a small proportion of ganglioneuromas are adrenal in origin and occur most commonly in children and young adults. Characteristically, ganglioneuromas do not secrete excess catecholamines or steroid hormones, and they are usually clinically silent lesions incidentally detected in imaging studies for unrelated reasons. Because it is an uncommon lesion, adrenal ganglioneuromas is not included in the differential diagnosis of adrenal incidentalomas in adults. We presents a new case of a 6.5 cm adrenal ganglioneuroma incidentally diagnosed in a 50-year old male patient. The exeresis of the adrenal mass and pathohistological study confirmed the diagnosis.
