Preoperative characteristics of eight pediatric and young adult patients referred for excision of suspicious or cancerous lesions.

Age (years)	Wt (kg)	Location of mass	Size of mass (cm)	Nephrometry score	Preoperative diagnosis
26	57	Renal	3.5	8A	Suspicious mass
13	79	Renal	3.2	9A	Suspicious mass
3	14	Renal	2.1	5A	Suspicious mass
12	33	Renal	1.5	8A	Suspicious mass
17	75	Retroperitoneal	2.0	–	Mixed NSGCT RP mass w LN
16	78	Retroperitoneal	na	–	Paratesticular RMS
7	31	Adrenal	6.4	–	Suspicious mass Elevated catecholamines
19	60	Renal	9.8		Suspicious mass, RP LN

Wt = weight; NSGCT = non-seminomatous germ cell tumor; RP = retroperitoneum; LN = lymphadenopathy; RMS = rhabdomyosarcoma.
