Patient data

	Hereditary phaeochromocytoma		Non-syndromic phaeochromocytoma^*
	MEN 2	VHL	Adrenergic	Noradrenergic
n	13	18	15	11
Gender (F/M)	9/4	10/8	4/11	6/5
Age (mean, range)	38 (17-75)	28 (10-50)	57 (30-75)^†^§	47 (22-67)^†

Patients with non-syndromic phaeochromocytoma are divided into two subgroups with either a noradrenergic (noradrenaline predominant) or adrenergic (mixed adrenaline and noradrenaline) biochemical phenotype as described elsewhere (3, 10).

^†

Significantly (P < 0.02) higher age than in VHL patients
