Lymphoma cells show strong reactivity for CD56. B: Strong
staining is visible for CD8. C: Cytoplasmic granules are
positive for TIA-1. D: Histology shows densely packed
monomorphic medium-sized cells with round nuclei, small nucleoli, and
moderately wide pale or clear cytoplasm; inflammatory cells and
fibrosis are not seen. Giemsa staining; magnification, x390
