Huge Ganglioneuroma of the Suprarenal Gland: A Surgery Case Report of a Rare Location

Ganglioneuroma is a benign neoplasm that originate from neural crest cells and characterized by well-differentiated cells such as mature Schwann cells, ganglion cells. Ganglioneuroma rarely occurs in the adrenal gland, making diagnosis challenging. Ganglioneuromas do not produce excessive catecholamines or steroid hormones, and they often remain clinically silent and asymptomatic, even when they reach a large size. The detection of this tumor has improved due to the availability of imaging techniques such as ultrasonography, computed tomography, and magnetic resonance imaging. However, histopathology remains the gold standard for confirming the diagnosis definitively and distinguishing it from a malignant tumor.
