Patient's question:
Male, 8 years old, onset of illness in April 2012. Initially, it was stomach pain, later red spots appeared on both feet.Doctor's answer:
Certain infections can cause abnormal white blood cells, such as infectious mononucleosis, where atypical lymphocytes appear in the blood count, but their morphology is different from that of primitive cells. The titer of heterophile antibodies in the serum gradually rises, and the course of the disease is short, often self-limiting. During viral infections like whooping cough, infectious lymphocytosis, and rubella, lymphocytes increase in the blood count, but their morphology is normal. The course of the disease is benign, and it is often self-limiting.
