About Burkitt's lymphoma, true is-
Burkitt's lymphoma is a tumor of mature B cells that express surface IgM, CD19, CD20, CD10, and BCL6, a phenotype consistent with a germinal center B-cell origin.
Unlike other tumors of germinal center origin, Burkitt lymphoma almost always fails to express the antiapoptotic protein BCL2 (This information has been added in 8th of Robbin's)
