5 July 2026 (Sunday) - NEQAS 2603 BF

I got the results of NEQAS 2603BF today.
 

For 2603 BF1 I said

 

Hairy cells  (consensus 1^st)

Lymphocytosis (consensus 4^th)

low plts (consensus 3rd)

Neutropenia (consensus 5th)

NRBC (consensus 2^nd)

 

I thought it was hairy cell leukaemia. It was.

 
For 2603 BF2 I said
 

Neutropenia (consensus 4^th)

low plts (consensus 1^st)

Blast cells (consensus 2^nd)

“iffy” lymphocytes (consensus 6^th)

Rouleaux (consensus 5^th)

 

I thought it was “???”. It could have been any of a wide range of conditions. The expert opinion said “In essence the morphology, in isolation, suggests a wide differential diagnosis”.

 

I’ll take that…
