Case 54 – case A

This week we are going to look at a range of short cases, some of which are morphology based, and most will include MCQ questions.  The discussion does not have to be limited to the basic answer – please feel free to add further information/thoughts/questions about a case if you wish!


The cases will be released gradually throughout the week, however should you wish to look at a few together towards the end of the week, you can still join in the answering process – each case will be labelled with a letter – just include this letter at the beginning of your tweet.  Everyone can give the MCQs a go, and the answers will be released at the end of the week with the case summaries.


Case A



This first patient is a 48 year old man who presented with neutropenia and monocytopenia.  He was found to have splenomegaly on examination.

b) CD20 +,CD5+, CD23+, FMC7 -,SmIg weak, CD79b –

c) CD20+, CD5+, CD23-, FMC7+. SmIg weak, cd79b +

d) CD20+ CD5-, CD23-, CD103 +, CD11C +, CD10-, CD123+

e) CD20+, CD5-, CD10+, CD19+, CD22+, CD79a+
