Synchronous ipsilateral adrenal cortical adenoma and ganglioneuroma: A case report

Synchronous tumors comprising of cortical as well as medullary differentiation are rare in the adrenal gland. Collision tumors comprise of two independent neoplasms arising from the cortex and the medulla without any histological admixture. Adrenal cortico-medullary mixed tumors are rare tumors comprising of adrenal cortical and chromaffin cells intermixed with each other. Ganglioneuroma is a rare benign tumor originating from the paravertebral sympathetic ganglia and is rarely seen in the adrenal medulla. The presence of a synchronous ganglioneuroma with an adrenal cortical adenoma in the ipsilateral adrenal gland is exceedingly rare. We report a collision tumor comprising of an adrenal cortical adenoma and a ganglioneuroma detected as an incidental finding in a pediatric patient who presented with hypertension and palpitations.
