Pediatric leukemia

This disease, also known as leukemia-like reaction, refers to a significant increase in the number of peripheral white blood cells or the appearance of naive cells after the body is stimulated by a certain factor, much like leukemia rather than leukemia, a temporary leukocyte hyperplasia response. Except for chronic myelogenous leukemia, the white blood cell count generally does not exceed 50 × 109 / L, but occasionally it can exceed 50 × 109 / L, or even 100 × 109 / L, and the blood is neutral. The left shift of granulocyte nuclei is obvious, and there are more late myelocytes, mesenchymal cells, and even a small number of promyelocytic and promyelocytic cells. This phenomenon is somewhat similar to chronic myelogenous leukemia, so it becomes a leukocyte-like reaction. There are many types, including granulocyte type, erythroleukemia type, plasma cell type, and mixed cell type. Among them, neutrophil type is the most common.
