Is immunohistochemistry mandatory in staging bone marrow trephine biopsy of patients with diffuse large B-cell lymphoma (DLBCL)

Diffuse large B-cell lymphoma (DLBCL) can be found involving bone marrow in approximately 11-27% of cases 1. Patterns of involvement are variable; these include diffuse pattern (lymphomatous cells diffusely infiltrating the marrow), interstitial pattern (i.e. small amount of lymphomatous cells scattered among hematopoietic cells), nodular pattern (lymphomatous cells forming aggregates in intertrabecular or paratrabecular area of the marrow).. ...
