Mystery cells, case #3
This interesting mystery cells case is presented by Margit Grome, Biomedical Laboratory Scientist, Department of Clinical Biochemistry at Rigshospitalet, Copenhagen University Hospital.
Here are the patient details:
A 4 year-old boy, hospitalized at the Department of Paediatrics.
Cell count at the Sysmex XE-2100 showed, click to enlarge.
The Sysmex XE-2100 could not perform a differential count but gave the alarm:
“Atypical Lympho ? and Abn Lympho/L_Blasts?”
We validated 400 cells in the CellaVision DM96. We were a bit surprised to see 10% of – rather immature looking – mononuclear cells.
