>Hi,
There are cases of higly malignant T cell NHL and even very rare cases of
large cell B-cell NHL (which are not KI-1 NHL by morphology and other
markers) that are CD30 positive. Moreover occasional T cells in HD lymph
nodes can be CD30+.
R-S cells are difficult to get in suspension and FCM methods are of very
limited use in diagnosis. We usually do immunostaining on paraffin/frozen
sections.
