    In the old literature this cases were named mid facialdestructive polymorphic reticulosis before the origin of natural T killer cells. One feature that it is not display is a consistent angiocentric invasion that is a diagnostic feature that helps primary in the dx before performing thr ICH studies.

    very nice case. my diagnosis is NK/T cell lymphoma. ..thank you for providing the IHC results, becous from the history it is a lymphoma, you exclude the possibility of carcinoma by the use of cytokeratin. then for the immuonphenotyping you use long list of antibodies, from economic point of view is it necessary to use such long banal?? thank you so much .

    NK cell /T cell lymphoma though not very common, has high prevalence in Orient and some parts of Latin America and has strong association with EBV . In WHO classification, some are seperately classified as nasal type, extranodal, its imp for pathologists and oncologists to differentiate this group from other lymphomas as these are generally associated with poorer prognosis, more relapses and lesser response to chemo and radiotherapy. CD 56 is the marker responsible for dissemination of tumour cells. Very interesting case, good pics and thanks for providing IHC details
