Abstract
Neuroblastic tumors are the third most common cause of solid tumors in early childhood. Cervical tumors account for only 5% of cases. In this report, we describe a series of four pediatric neuroblastic tumors of the neck. The histological diagnosis was ganglioneuroblastoma in three cases and neuroblastoma in one case. Presenting signs were solitary cervical mass in two cases and respiratory distress in association with Claude-Bernard Horner's syndrome in two cases. Mean age at presentation was 15 months. Cervical computed tomography scan and/or magnetic resonance imaging depicted calcifications within the tumor in 50% of cases and allowed accurate assessment of extension. Increased urine catecholamine levels were observed only in the patient with neuroblastoma. Scintigraphy with [131]iodine-methyliodobenzylguanidine demonstrated selective uptake by the tumor in two cases. Amplification of N-myc oncogene, a documented unfavorable prognostic sign, was not found in any case. Surgical treatment was performed in all patients. Neoadjuvant chemotherapy was performed in one case. All patients underwent regular surveillance. No evidence of recurrence has been observed with a mean follow-up period of 7 years.
