Persistence and possible progression of a pelvic neuroblastoma detected by mass screening during 19 months.
Purpose: The preclinical detection of neuroblastoma by screening for elevated levels of urinary catecholamines often leads to the discovery of children with early-stage, biologically favorable disease. It is uncertain how vigorously therapy must be pursued in such cases. We report an infant whose pelvic mass was initially thought to be a fecaloma, and consequently was not treated for 19 months.
Case report: A 2-month-old girl was referred for evaluation for the presence of a neuroblastoma because of elevated urinary catecholamines detected in a mass screening program. Although no mass was initially found, urinary catecholamines became increasingly elevated, and a pelvic mass was finally radiologically identified. It was resected. Histology showed it to be a neuroblastoma, POG stage C, International stage 3, with unfavorable Shimada features, although near triploid with an unamplified N-myc oncogene. Chemotherapy was given for five cycles, and the child remains well, with no evidence of disease.
Conclusion: Although mass screening programs often detect early- stage, biologically favorable neuroblastomas that may spontaneously regress, our case had rising levels of urinary catecholamines and unfavorable histologic features at the time of resection. The unusual location of the tumor, and radiologic features of a fecaloma, contributed to the delay in definitive diagnosis, although persistence of elevated urinary catecholamines in the absence of a tumor is infrequent.
