Incidentally Discovered Adrenal Schwannoma

Schwannoma is a rare tumor of neural crest cell origin that is rarely seen arising from the adrenal gland. We report a case of an adrenal mass discovered incidentally in a 70-year-old man as part of a hematuria workup. Metabolic evaluation was unremarkable, and imaging studies did not meet strict imaging criteria for a typical adenoma. Following surgical excision and pathologic evaluation with confirmatory immunohistochemical staining, the mass was reported as a benign nerve sheath neoplasm.
