【 摘 要 】

We present two cases of adrenal phaeochromocytoma in patients with a previous diagnosis of neurofibromatosis type 1(NF1). One had an adrenergic phenotype. The other had a more noradrenergic phenotype. Both had large primarytumours, which increases the likelihood of malignancy. Both also had elevated plasma-free methoxytyramine, whichhas been linked with malignancy even in non-SDHB phaeochromocytomas.
