<unk> <unk>  is an indolent CD20(+) form of lymphoma. Some medical organizations no longer classify it as a form of classic<unk>  lymphoma (HL). This is because the Reed-Sternberg cell (RSC) variants (popcorn cells) that characterize this form of the disease invariably express B<unk>  markers such as CD20 (thus making<unk>  an unusual form of<unk>  lymphoma), and that (unlike classic HL)<unk>  may progress to diffuse large B cell lymphoma. There are small but clear differences in prognosis between the various forms.<unk><unk>  HL is an uncommon subtype composed of vague nodules of numerous reactive<unk> s admixed with large popcorn-shaped RSC. Unlike classic RSC, the non-classic popcorn-shaped RS cells of<unk>  are CD15 and CD30 negative while positive for the B cell marker CD20. The anti-CD20 monoclonal antibody Rituximab has been used in<unk><unk><unk>  lymphoma with encouraging results. BCL6 gene rearrangements have been frequently observed.
