(A) Postoperative specimen of ovary tumor reduction: revealed deep infiltration by sheets of large to medium size cells with oval or round pleomorphic nuclei and scanty cytoplasm. (B) CD20 staining: B lymphoid cells population showing CD20 membrane expression is positive. (C) CD79a staining: CD79a membrane expression is positive. (D) CD3 staining: B lymphoid cells population showing CD3 membrane expression is negative. (E) Ki-67 staining: Ki-67 is expressed positivity in 90% tumor cells. (F) CD10 staining: CD10 membrane expression is positive
