A: The poorly differentiated tumor showed a cluster appearance and a fibrovascular septum in case 1 (hematoxylin and eosin stain, × 200 magnification); B: Neuropil-like element in the tumor of case 1 (blue arrow, hematoxylin and eosin stain, × 200); C: The tumor cells were positive for synaptophysin in case 1 (× 200 magnification); D: The tumor cells show myelocytomatosis viral related oncogene, neuroblastoma derived amplification, which is indicated by the number of myelocytomatosis viral related oncogene, neuroblastoma derived signals (green) [more than 8 copies of the centrosomal probe signals (red)].
