We present the case of a 57-year-old male patient diagnosed with Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL). The initial diagnosis included clinical findings such as hepatomegaly and splenomegaly, accompanied by extreme leukocytosis. Molecular studies confirmed the presence of the Philadelphia chromosome, with cytogenetic studies showing resistance to tyrosine kinase inhibitors such as dasatinib. The patient received multiple treatments, including imatinib, dasatinib, and later bosutinib. Complete blood counts and bone biopsies showed infiltration of lymphoid blasts and hematologic complications such as neutropenia and severe anemia. During follow-up, no hematologic or molecular response was observed. Management was limited by the patient's refusal to receive intensive chemotherapy and the lack of availability of allogeneic transplantation in Honduras.
