Acute lymphoid leukemia (LLA): A pediatric case report in dizygotic twins

Acute leukemias are considered neoplasias that reach the hematopoietic system, resulting in rapid clonal expansion and accelerated proliferation of blood cells. In this way, the cells lose their capacity for maturation and differentiation, accumulating young cells (blasts) and without function in the bone marrow. Acute lymphocytic leukemia (ALL) is a neoplasm that affects cells of the lymphoid lineage, but its prevalence occurs in B-cell precursors compared to T cells. It is common to occur in children between 1 and 5 years of age, comprising about 80% of the cases of all leukemias in this age group, but in adults, the probability of being present is lower. The present study aimed at the accomplishment of a case report on acute lymphoid leukemia in children, based on the comparison of risk factors in the family, and the evaluation of socioeconomic interference in the treatment, where, through an explanatory booklet, health professionals and the community about the major signs and symptoms of ALL in children. The research was submitted to the Ethics Committee of the Catholic University Center of Quixadá, through the Brazil Platform where it was analyzed and approved (01673218.2.0000.5046). In this study, we reported the case of two twin sisters who entered the Hospital São Sebastião de Pedra Branca, Ceará at different times, where one was admitted with fever and boulders, and another presenting only fever, after laboratory tests they were referred to a referral hospital in Fortaleza, Ceará, and were then diagnosed with acute lymphoid leukemia. Due to the poor prognosis of this pathology and a possible worsening of the patients' clinical status, they were referred for bone marrow transplantation. Fortunately, after the treatments performed, the twin had a positive evolution, no longer needing to undergo bone marrow transplantation.
