Neurofibromatosis (NF) is a hereditary disease and carries increased risk of both
benign and malignant tumor development. Pheochromocytoma or hyperparathyroidism have
been reported to be associated with NF type 1 (NF1). However, the coexistance of pheochromocytoma
and parathyroid adenoma in a patient with NF1 is very rare. We report a case of a
37-year-old male with NF1, bilateral pheochromocytoma and parathyroid adenoma. This
association sould be kept in mind in patients with NF1 in initial evaluation as well
as during follow-up.
