Abstract: An adrenal incidentaloma (AI) is an asymptomatic adrenal mass at least 1 cm in diameter detected on imaging studies performed for non-adrenal related disease. Amyloidosis is a rare disease and its presentation as an adrenal gland incidentaloma without systemic disease is exceptional. We present a 62-year-old woman with history of blunt abdominal trauma secondary to a vehicle accident 18 months ago. During her clinical assessment, an abdominal CT-scan was performed showing an AI with malignancy-suspicious features. Laparoscopic right adrenalectomy was performed. Histopathological examination exhibited amyloid infiltration in the hematoxylin and eosin (HE) staining, and it was confirmed by a positive Congo Red (CR) staining and a positive kappa and lambda chains immunohistochemistry.

 

Key Words: Adrenal incidentaloma, laparoscopic adrenalectomy.
