Cytomorphologic features associated with nodal marginal zone lymphoma

The cytomorphologic features associated with NMZL include: (A) vague nodularity, often associated with the diffuse pattern; (B) sclerosed blood vessels closely associated with neoplastic cells; and (C) fine stromal sclerosis that appeared to compartmentalize small groups of neoplastic cells. The typical cell milieu in NMZL showed: (D) a range from small to medium sized cells with clear cytoplasm (monocytoid cells) with occasional admixed large cells; (E) increased large cells with nuclear pleomorphism; and (F) plasmacytoid cells scattered singly and in clusters.
