>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.
