A Rare Case of Solitary Retroperitoneal Neurofibroma Mimicking Carcinoma of the Adrenal Gland

Abstract

Neurofibroma, a benign tumor of neural origin, indicates a possible differential diagnosis of adrenal masses in rare cases. It can be solitary or associated with neurofibromatosis type 1. Neurofibroma in the visceral compartment is an uncommon location and considered extremely rare. While it has a very low potential for malignant transformation, accurate diagnosis is nonetheless essential to allow for adequate treatment. In this article, we report a case of a patient with right-sided abdominal pain, fatigue and B symptoms (night sweats and weight loss) as a result of an adrenal tumor measuring 12 cm. The tumor was highly suspicious for malignancy, but the surgical resection revealed a benign neurofibroma. This case report describes a diagnostic and treatment pathway for nonspecific adrenal lesions.
