Morphology of primary intestinal NK-cell lymphoma and peripheral T-cell lymphoma NOS. (a–d) Histology, immunophenotype, and EBER in situ hybridization of a primary intestinal NK-cell lymphoma. At medium power, tumor cells of NK-cell lymphoma are small to medium sized (a), negative for βF-1 (b), positive for CD56 (c), and positive for EBER in the majority of tumor cells (d). (e–h) Histology, immunophenotype, and EBER in situ hybridization of a peripheral T-cell lymphoma NOS. At medium power, tumor cells of this case of peripheral T-cell lymphoma NOS are medium to large sized (e), positive for βF-1 (f), and negative for CD56 (g) and have scattered EBER-positive cells (h).
