Leukemia Lymphoblastic

Lymphoblastic leukemia (l. lymphoblastica; synonym acute lymphocytic leukemia) is a malignant disease of the hematopoietic system, characterized by the proliferation of immature lymphoid cells (lymphoblasts) in the bone marrow, blood, and lymphoid tissue.

The disease is more common in children, less common in adults. Tumor cells infiltrate the bone marrow, displacing normal hematopoietic cells, resulting in anemia, neutropenia, and thrombocytopenia. There is also an increase in lymph nodes, liver, and spleen.

Treatment includes chemotherapy and bone marrow transplantation. The prognosis depends on the form and stage of the disease. In some cases, timely treatment can achieve stable remission.

Leukemia is a group of tumor diseases characterized by metaplasia of hematopoietic tissue and an increase in the number of pathological myeloid or lymphoid cells in the bone marrow. In this case, attention will be paid to leukemia, a malignant tumor of the lymphatic system. It includes a heterogeneous group of tumor processes developing not only in the bone marrow, but also in the lymphatic marrow.

Lymphoblastic leukemia 4. Acute lymphocytic leukemia

**Synonyms: lymphoplasmacytic leukemia, acute lymphoma** Acute lymphocytic leukemia is a lymphoproliferative disease in which rapid division of lymphatic tissue occurs, as a result of which the functioning of organs and systems of the body is disrupted and their destruction develops. In some cases, these changes may be irreversible.

Symptoms of acute lymphoblastic leukemia. Primary manifestations: 1) Rapid development of weakness, anemia and weight loss. 2) Due to compression of the efferent vein by the tumor, an ulcer forms on the patient’s legs (mainly on the legs). 3) Recurrent rashes of lymphadenitis. 4) Rashes of the visceral lymph nodes behind the ear. 5) Purple-red or bluish rashes on the skin called petechiae. 6) Redness inside the blood vessels of the neck, upper torso and limbs (so-called intravascular
