Key result
FNA of BCOR-CCNB3 sarcoma reveals mainly dispersed round and rhabdoid-like cells without rosette formation.
Why the study?
BCOR-CCNB3 sarcoma is an undifferentiated tumor with some similarity to classic Ewing sarcoma, but reports describing its cytomorphologic findings were lacking.

May aid FNA differentiation of BCOR-CCNB3 sarcoma; leaves open validation in larger series.
Case Report (n=5)
Cytologic features such as rhabdoid-like cells, connective tissue fragments, and pseudopapillary formations can help differentiate BCOR-CCNB3 sarcoma from other round cell tumors.
Gajdzis et al. (2019) conducted a case report in BCOR-CCNB3 sarcoma (n=5). Fine-needle aspiration cytology was evaluated on Cytomorphologic findings. Fine-needle aspiration of BCOR-CCNB3 sarcoma revealed mainly round cells, dispersed cells, pseudopapillary structures, and rhabdoid-like cells without rosette formation.
