Morphology Monday | Case MM250818

This week's Morphology Monday case comes from a 35 year old male who presented with:

• Fatigue and pallor

• Easy bruising

• Reduced urine output

• Mild abdominal pain following a recent gastrointestinal illness

The full blood count results showed the following:

• Hb: 113 g/L

• WBC: 5.46 ×10⁹/L

• PLT: 16 ×10⁹/L

Due to the severely low PLT results a blood film was made. The images are below:

Biochemistry results:

• Creatinine: 257 μmol/L

• Bilirubin: 49 μmol/L

• ALT: 77 U/L

• Calcium: 1.84 mmol/L

• Phosphate: 0.4 mmol/L

Other results:

• ADAMTS13 activity: 64.7 IU/dL (within normal range)

Given the clinical presentation, the laboratory investigation results and the blood film images, what do you think is wrong with the patient?
