Abstract
BACKGROUND: Neuroblastomas are rare tumors activated by the FoxR2 gene commonly found in pediatric patients. Due to the novelty of these tumors, there is no standard diagnostic profile. However, they have been found to express Olig2, MAP2, SOX10, ANKRD55, and synaptophysin, and they can be identified with magnetic resonance imaging (MRI). Treatment with chemotherapy combined with stem cell rescue and craniospinal irradiation can improve non-infant patient outcomes. CASE DESCRIPTION: We report a case of a 2-year-old patient who was diagnosed with a neuroblastoma through MRI imaging and pathology that confirmed FoxR2 gene activation. The tumor was successfully removed. However, the tumor was not high-grade like most FoxR2 neuroblastomas. CONCLUSION: The unusual presentation of a low-grade FoxR2 neuroblastoma demonstrates the necessity to conduct further research into the characteristics of these tumors.
