Question 6:

A 46-year-oldwoman presented to her GP with a short history of breathlessness and increased bruising.A full blood count revealed she was anaemic with thrombocytopenia and a high lymphocyte count of 58x109/L. The patient's bone marrow morphology is shown below.

 

FIGURE Q6a

a) Please describe and explain the abnormal features shown in FIGURE Q6a.

The patient's bone marrow was then further tested and the following results were obtained.

 

FIGURE Q6b

b) Which diagnostic technique produced the data shown in FIGURE Q6b?

c) Which diagnostic feature, relating to chromosomes 9 and 22, appears in FIGURE Q6b?

c) Please suggest other tests that the laboratory should perform next and explain what these tests might be looking for.

d) What is the likely diagnosis for the patient? Please explain your answer.

e) What further tests are required to complete the diagnosis and/or monitor disease progression?

Question 7:

Patient is an 85-year-old male who feels generally fine and is visiting his doctor for a routine NHS health check. His FBC results are as follows (TABLE Q7):
