Musculoskeletal conditions of acute leukemia and malignant lymphoma in children.

Abstract

We retrospectively reviewed 16 patients who presented to hospitals with orthopaedic complaints. Twelve patients experienced initial symptoms in the extremities and four patients had back pain. The leukocyte count was elevated in one patient, decreased in two patients, and normal in 13 patients. On radiographic examination, osteopenia was observed in 10 patients, osteolytic lesions were observed in five, and pathologic fractures were observed in five. Because the initial presentation of patients with leukemia often involves the musculoskeletal system, orthopaedists need to recognize the symptoms of this disease to avoid misdiagnosis and to expedite the initiation of appropriate potentially lifesaving treatment.
