Neuroblastoma, Homer Wright Rosettes are circular groupings of dark tumor cells surrounding pale neurofibrils (small blue cell tumors from neural crest ectoderm). This histologic finding is found in neuroblastoma, medulloblastoma and retinoblastoma.
Characteristics of neuroblastoma include overexpression of the N-myc oncogene, bombesin tumor marker and neurofilament positive histological stains.
Note: Do not confuse with Perivascular Pseudorosettes/Rosettes found in Ependymomas
