B Sample after chemotherapy showed grey-yellow or brown tumors in the medullary cavity, some areas had gel appearance. C Tumor cells arranged in solid hypercellular sheets without a distinct architectural pattern. D Tumor cells arranged in a vague whirling pattern. E The tumor cells showed monomorphic, ovoid nuclei, with similar fine chromatin pattern. F Hypocellular myxoid areas was focally seen. G One case (case 7) was composed predominantly of primitive round cells. H One case (case 5) showed markedly perivascular arrangement and cell clustering.
