Suspected tumour cells were classified into small, intermediate and large sizes and two characteristic forms of plasmacytoid and Reed Sternberg\u2010like on smears (step 1), followed by utilising panels of immunohistochemical markers and Epstein\u2010Barr encoding region in situ hybridisation on cell blocks (step 2). A panel of <jats:styled-content style=\"fixed-case\">CD<\/jats:styled-content>3, <jats:styled-content style=\"fixed-case\">CD<\/jats:styled-content>20 and Ki\u201067 formed the basic workup, followed by pertinent batteries of immunostaining.
