Management of stage 4S composite neuroblastoma with a MYCN-amplified nodule. MYCN amplification in neuroblastoma is usually associated with a poor prognosis. Very few cases of heterogenous MYCN amplification have been previously reported, and the clinical significance of heterogeneity is unclear. We report a neonate with an adrenal stage 4S neuroblastoma with a small focus of MYCN-amplified cells within a nonamplified background. After adrenalectomy, the patient has been observed without use of chemotherapy and has no evidence of disease progression.
