Acute lymphoblastic leukemia (ALL) is a lymphoid malignancy characterized by impaired differentiation and proliferation of leukemic myeloblasts. Normal hematopoietic cells are replaced by excess myeloblasts, causing bone marrow failure. Therefore, patients with ALL typically present with symptoms related to infection, anemia, and thrombocytopenia. Extramedullary involvement of ALL as an initial presenting symptom has rarely been reported in adults, although several such cases of relapse have been described. Isolated extramedullary manifestations may lead to a late diagnosis of ALL. We describe herein a patient with Philadelphia chromosome-positive ALL presenting with an extramedullary bone tumor.
Keywords: Acute lymphoblastic leukemia; Extramedullary diasease
