Abstract

A 78-year-old woman was referred to our institution for evaluation and treatment of a mass on her right adrenal gland measuring 12 × 11 × 10 cm. Twenty-four-hour urine analysis revealed a total metanephrine level over 3 times the upper limit of normal. Scintigraphy using ¹²³I-metaiodobenzylguanidine was positive. The mass was resected en bloc by laparotomy after a laparoscopic attempt was unsuccessful. Histopathologic examination revealed a pheochromocytoma of the right adrenal gland, weighing 576 g. The Grading System for Adrenal Pheochromocytoma and Paraganglioma score was 6, and the histology of the tumor was a moderately differentiated type.

Keywords: Giant; Grading system for adrenal pheochromocytoma and paraganglioma; Pheochromocytoma.
